In a network like XRP Ledger, a single transaction touches multiple independent nodes—each with no shared memory or logging. Distributed tracing connects these dots. + +**Without tracing:** You see isolated logs on each node with no way to correlate them. + +**With tracing:** You see the complete journey of a transaction or an event across all nodes it touched. + +--- + +## Core Concepts + +### 1. Trace + +A **trace** represents the entire journey of a request through the system. It has a unique `trace_id` that stays constant across all nodes. + +``` +Trace ID: abc123 +├── Node A: received transaction +├── Node B: relayed transaction +├── Node C: included in consensus +└── Node D: applied to ledger +``` + +### 2. Span + +A **span** represents a single unit of work within a trace. Each span has: + +| Attribute | Description | Example | +| ---------------- | --------------------- | -------------------------- | +| `trace_id` | Links to parent trace | `abc123` | +| `span_id` | Unique identifier | `span456` | +| `parent_span_id` | Parent span (if any) | `p_span123` | +| `name` | Operation name | `rpc.submit` | +| `start_time` | When work began | `2024-01-15T10:30:00Z` | +| `end_time` | When work completed | `2024-01-15T10:30:00.050Z` | +| `attributes` | Key-value metadata | `tx.hash=ABC...` | +| `status` | OK, ERROR MSG | `OK` | + +### 3. Trace Context + +**Trace context** is the data that propagates between services to link spans together. It contains: + +- `trace_id` - The trace this span belongs to +- `span_id` - The current span (becomes parent for child spans) +- `trace_flags` - Sampling decisions + +--- + +## How Spans Form a Trace + +Spans have parent-child relationships forming a tree structure: + +```mermaid +flowchart TB + subgraph trace["Trace: abc123"] + A["tx.submit

--------------------------- | +| **Transaction** | `tx.hash`, `tx.type`, `tx.result`, `tx.fee`, `ledger_index` | Trace transaction lifecycle | +| **Consensus** | `round`, `phase`, `mode`, `proposers` (public keys), `duration_ms` | Analyze consensus timing | +| **RPC** | `command`, `version`, `status`, `duration_ms` | Monitor RPC performance | +| **Peer** | `peer.id` (public key), `latency_ms`, `message.type`, `message.size` | Network topology analysis | +| **Ledger** | `ledger.hash`, `ledger.index`, `close_time`, `tx_count` | Ledger progression tracking | +| **Job** | `job.type`, `queue_ms`, `worker` | JobQueue performance | + +### 2.4.4 Privacy & Sensitive Data Policy + +OpenTelemetry instrumentation is designed to collect **operational metadata only**, never sensitive content. + +#### Data NOT Collected + +The following data is explicitly **excluded** from telemetry collection: + +| Excluded Data | Reason | +| ----------------------- | ----------------------------------------- | +| **Private Keys** | Never exposed; not relevant to tracing | +| **Account Balances** | Financial data; privacy sensitive | +| **Transaction Amounts** | Financial data; privacy sensitive | +| **Raw TX Payloads** | May contain sensitive memo/data fields | +| **Personal Data** | No PII collected | +| **IP Addresses** | Configurable; excluded by default in prod | + +#### Privacy Protection Mechanisms + +| Mechanism | Description | +| ----------------------------- | ------------------------------------------------------------------------- | +| **Account Hashing** | `xrpl.tx.account` is hashed at collector level before storage | +| **Configurable Redaction** | Sensitive fields can be excluded via `[telemetry]` config section | +| **Sampling** | Only 10% of traces recorded by default, reducing data exposure | +| **Local Control** | Node operators have full control over what gets exported | +| **No Raw Payloads** | Transaction content is never recorded, only metadata (hash, type, result) | +| **Collector-Level Filtering** | Additional redaction/hashing can be configured at OTel Collector | + +#### Collector-Level Data Protection + +The OpenTelemetry Collector can be configured to hash or redact sensitive attributes before export: + +```yaml +processors: + attributes: + actions: + # Hash account addresses before storage + - key: xrpl.tx.account + action: hash + # Remove IP addresses entirely + - key: xrpl.peer.address + action: delete + # Redact specific fields + - key: xrpl.rpc.params + action: delete +``` + +#### Configuration Options for Privacy + +In `rippled.cfg`, operators can control data collection granularity: + +```ini +[telemetry] +enabled=1 + +# Disable collection of specific components +trace_transactions=1 +trace_consensus=1 +trace_rpc=1 +trace_peer=0 # Disable peer tracing (high volume, includes addresses) + +# Redact specific attributes +redact_account=1 # Hash account addresses before export +redact_peer_address=1 # Remove peer IP addresses +``` + +> **Key Principle**: Telemetry collects **operational metadata** (timing, counts, hashes) — never **sensitive content** (keys, balances, amounts, raw payloads). + +--- + +## 2.5 Context Propagation Design + +### 2.5.1 Propagation Boundaries + +```mermaid +flowchart TB + subgraph http["HTTP/WebSocket (RPC)"] + w3c["W3C Trace

Architecture Analysis + +The rippled node consists of several key components that require instrumentation for comprehensive distributed tracing. The main areas include the RPC server (HTTP/WebSocket), Overlay P2P network, Consensus mechanism (RCLConsensus), JobQueue for async task execution, and existing observability infrastructure (PerfLog, Insight/StatsD, Journal logging). + +Key trace points span across transaction submission via RPC, peer-to-peer message propagation, consensus round execution, and ledger building. The implementation prioritizes high-value, low-risk components first: RPC handlers provide immediate value with minimal risk, while consensus tracing requires careful implementation to avoid timing impacts. + +➡️ **[Read full Architecture Analysis](./01-architecture-analysis.md)** + +--- + +## 2. Design Decisions + +The OpenTelemetry C++ SDK is selected for its CNCF backing, active development, and native performance characteristics. Traces are exported via OTLP/gRPC (primary) or OTLP/HTTP (fallback) to an OpenTelemetry Collector, which provides flexible routing and sampling. + +Span naming follows a hierarchical `.` convention (e.g., `rpc.submit`, `tx.relay`, `consensus.round`). Context propagation uses W3C Trace Context headers for HTTP and embedded Protocol Buffer fields for P2P messages. The implementation coexists with existing PerfLog and Insight observability systems through correlation IDs. + +**Data Collection & Privacy**: Telemetry collects only operational metadata (timing, counts, hashes) — never sensitive content (private keys, balances, amounts, raw payloads). Privacy protection includes account hashing, configurable redaction, sampling, and collector-level filtering. Node operators retain full control(not penned down in this document yet) over what data is exported. + +➡️ **[Read full Design Decisions](./02-design-decisions.md)** + +--- + +## 3. Implementation Strategy + +The telemetry code is organized under `include/xrpl/telemetry/` for headers and `src/libxrpl/telemetry/` for implementation. Key principles include RAII-based span management via `SpanGuard`, conditional compilation with `XRPL_ENABLE_TELEMETRY`, and minimal runtime overhead through batch processing and efficient sampling. + +Performance optimization strategies include probabilistic head sampling (10% default), tail-based sampling at the collector for errors and slow traces, batch export to reduce network overhead, and conditional instrumentation that compiles to no-ops when disabled. + +➡️ **[Read full Implementation Strategy](./03-implementation-strategy.md)** + +--- + +## 4. Code Samples + +Complete C++ implementation examples are provided for all telemetry components: + +- `Telemetry.h` - Core interface for tracer access and span creation +- `SpanGuard.h` - RAII wrapper for automatic span lifecycle management +- `TracingInstrumentation.h` - Macros for conditional instrumentation +- Protocol Buffer extensions for trace context propagation +- Module-specific instrumentation (RPC, Consensus, P2P, JobQueue) + +➡️ **[View all Code Samples](./04-code-samples.md)** + +--- + +## 5. Configuration Reference + +Configuration is handled through the `[telemetry]` section in `xrpld.cfg` with options for enabling/disabling, exporter selection, endpoint configuration, sampling ratios, and component-level filtering. CMake integration includes a `XRPL_ENABLE_TELEMETRY` option for compile-time control. + +OpenTelemetry Collector configurations are provided for development (with Jaeger) and production (with tail-based sampling, Tempo, and Elastic APM). Docker Compose examples enable quick local development environment setup. + +➡️ **[View full Configuration Reference](./05-configuration-reference.md)** + +--- + +## 6.

Observability Backends + +For development and testing, Jaeger provides easy setup with a good UI. For production deployments, Grafana Tempo is recommended for its cost-effectiveness and Grafana integration, while Elastic APM is ideal for organizations with existing Elastic infrastructure. + +The recommended production architecture uses a gateway collector pattern with regional collectors performing tail-based sampling, routing traces to multiple backends (Tempo for primary storage, Elastic for log correlation, S3/GCS for long-term archive). + +➡️ **[View Observability Backend Recommendations](./07-observability-backends.md)** + +--- + +## 8.

Dropped traces incur near-zero overhead (no spans created, no attributes set, no export). | +| **Propagation** | Once a trace is sampled, the `trace_flags` field (1 byte in the context header) tells downstream nodes to also sample it. Unsampled traces propagate `trace_flags=0`, so downstream nodes skip them too. | +| **Pros** | Lowest overhead. Simple to configure. Predictable resource usage. | +| **Cons** | **Blind** — it doesn't know if the trace will be interesting.

The **Batch Processor** groups spans (1s timeout, batch size 100) before forwarding to trace backends. The **SpanMetrics Connector** derives RED metrics (rate, errors, duration) from every span and feeds them into the metrics pipeline. +2. **beast::insight StatsD** — System-level gauges, counters, and timers emitted as StatsD UDP packets to port :8125, ingested by the collector's **StatsD Receiver**, and exported alongside span-derived metrics to Prometheus. + +**Trace backends** — The collector exports traces via OTLP/gRPC to one or both: + +- **Jaeger** (development) — Provides trace search UI at `:16686`.

OTLP uses HTTP/gRPC with retries, binary protobuf encoding, and connection-level flow control. + +3. **Fixes the `|m` wire format issue** — The `StatsDMeterImpl` uses non-standard `|m` StatsD type that the OTel StatsD receiver silently drops. Native OTel counters eliminate this problem entirely (Phase 6 Task 6.1 — DEFERRED becomes resolved). + +4. **Richer metric semantics** — OTel Metrics SDK supports explicit histogram bucket boundaries, exemplars (linking metrics to traces), resource attributes, and metric views. StatsD has no concept of these. + +5. **Removes infrastructure dependency** — No more StatsD receiver needed in the OTel Collector. One less receiver to configure, monitor, and debug. Simplifies the collector YAML. + +6. **Metric-to-trace correlation** — OTel metrics and traces share the same resource attributes (service.name, service.instance.id). Grafana can link from a metric spike directly to the traces that caused it — impossible with StatsD-sourced metrics. + +7. **Production-grade export** — OTel's `PeriodicMetricReader` provides configurable export intervals, batch sizes, timeout handling, and graceful shutdown — all built into the SDK rather than hand-rolled in `StatsDCollectorImp`. + +#### What We Lose + +1. **StatsD ecosystem compatibility** — Operators using external StatsD-compatible backends (Datadog Agent, Graphite, Telegraph) will need to switch to OTLP-compatible backends or keep `server=statsd` as a fallback. + +2. **Simplicity of UDP** — StatsD's UDP fire-and-forget model is dead simple and has zero connection management. OTLP/HTTP requires a TCP connection, TLS negotiation (in production), and retry logic. The OTel SDK handles this, but it's more moving parts. + +3. **Slightly higher memory** — OTel SDK maintains internal aggregation state for metrics before export. StatsD just formats and sends strings. Expected overhead: ~1-2 MB additional for metric state. + +4. **Dependency on OTel C++ Metrics SDK stability** — The Metrics SDK is GA since 1.0 and on version 1.18.0, but it's less battle-tested than the tracing SDK in the C++ ecosystem. + +#### Decision + +The gains (unified pipeline, delivery guarantees, metric-trace correlation, simpler collector config) significantly outweigh the losses. `StatsDCollector` is retained as a fallback via `server=statsd` for operators who need StatsD ecosystem compatibility during the transition period. + +### Architecture + +#### Class Hierarchy (after Phase 7) + +``` +beast::insight::Collector (abstract interface — unchanged) + | + +-- StatsDCollector (existing — retained as fallback, deprecated) + | +-- StatsDCounterImpl -> StatsD |c over UDP + | +-- StatsDGaugeImpl -> StatsD |g over UDP + | +-- StatsDMeterImpl -> StatsD |m over UDP (non-standard) + | +-- StatsDEventImpl -> StatsD |ms over UDP + | +-- StatsDHookImpl -> 1s periodic callback + | + +-- NullCollector (existing — unchanged, used when disabled) + | +-- NullCounterImpl -> no-op + | +-- NullGaugeImpl -> no-op + | +-- NullMeterImpl -> no-op + | +-- NullEventImpl -> no-op + | +-- NullHookImpl -> no-op + | + +-- OTelCollector (NEW — Phase 7) + +-- OTelCounterImpl -> otel::Counter + +-- OTelGaugeImpl -> otel::ObservableGauge + +-- OTelMeterImpl -> otel::Counter + +-- OTelEventImpl -> otel::Histogram + +-- OTelHookImpl -> 1s periodic callback (same pattern) +``` + +#### Data Flow (after Phase 7) + +```mermaid +graph LR + subgraph rippledNode["rippled Node"] + A["Trace Macros

When investigating an issue, operators must manually correlate timestamps between log files and Jaeger/Tempo traces. Phase 8 bridges this gap by injecting trace context (`trace_id`, `span_id`) into every log line emitted within an active span, and ingesting those logs into Grafana Loki via the OTel Collector's filelog receiver. + +#### Gains + +1. **One-click trace-to-log navigation** — Click a trace in Tempo/Jaeger and immediately see the corresponding log lines in Loki, filtered by `trace_id`. +2. **Reverse lookup (log-to-trace)** — Loki derived fields make `trace_id` values clickable links back to Tempo. +3. **Unified observability** — All three pillars (traces, metrics, logs) flow through the same OTel Collector pipeline and are visible in a single Grafana instance. +4. **Zero new dependencies in rippled** — Uses existing OTel SDK headers (`GetSpan`, `GetContext`) already linked in Phase 1. +5. **Negligible overhead** — `GetSpan()` + `GetContext()` are thread-local reads (<10ns/call). At ~1000 JLOG calls/min, this adds <10us/min. + +#### Losses / Risks + +1. **Log format change** — Existing log parsers that rely on a fixed format will need updating to handle the optional `trace_id=... span_id=...` fields. +2. **Loki resource usage** — Log ingestion adds storage and memory overhead to the observability stack (mitigated by retention policies). +3. **Filelog receiver complexity** — The regex parser must be kept in sync with the log format; a format change in `Logs::format()` could break parsing. + +#### Decision + +The correlation value far outweighs the risks. The log format change is backward-compatible (fields are appended only when a span is active), and the filelog receiver regex is straightforward to maintain. + +### Architecture + +Phase 8 has two independent sub-phases that can be developed in parallel: + +- **Phase 8a (code change)**: Modify `Logs::format()` in `src/libxrpl/basics/Log.cpp` to append `trace_id= span_id=` when the current thread has an active OTel span.

Every metric in `expected_metrics.json` must have > 0 series. +- **StatsD gauge fix**: `StatsDGaugeImpl` initializes `m_dirty = true` so all gauges emit their initial value on first flush. Without this, gauges starting at 0 that never change (e.g. `jobq_job_count`) would be invisible in Prometheus. +- **I/O latency fix**: `io_latency_sampler` emits unconditionally on first sample, then applies the 10 ms threshold. This ensures `ios_latency` is registered in Prometheus even in low-load CI environments. +- **tx.receive span**: Sets default attributes (`xrpl.tx.suppressed = false`, `xrpl.tx.status = "new"`) on span creation so they are always present.

Architecture Analysis + +The rippled node consists of several key components that require instrumentation for comprehensive distributed tracing. The main areas include the RPC server (HTTP/WebSocket), Overlay P2P network, Consensus mechanism (RCLConsensus), JobQueue for async task execution, and existing observability infrastructure (PerfLog, Insight/StatsD, Journal logging). + +Key trace points span across transaction submission via RPC, peer-to-peer message propagation, consensus round execution, and ledger building. The implementation prioritizes high-value, low-risk components first: RPC handlers provide immediate value with minimal risk, while consensus tracing requires careful implementation to avoid timing impacts. + +➡️ **[Read full Architecture Analysis](./01-architecture-analysis.md)** + +--- + +## 2. Design Decisions + +The OpenTelemetry C++ SDK is selected for its CNCF backing, active development, and native performance characteristics. Traces are exported via OTLP/gRPC (primary) or OTLP/HTTP (fallback) to an OpenTelemetry Collector, which provides flexible routing and sampling. + +Span naming follows a hierarchical `.` convention (e.g., `rpc.submit`, `tx.relay`, `consensus.round`). Context propagation uses W3C Trace Context headers for HTTP and embedded Protocol Buffer fields for P2P messages. The implementation coexists with existing PerfLog and Insight observability systems through correlation IDs. + +**Data Collection & Privacy**: Telemetry collects only operational metadata (timing, counts, hashes) — never sensitive content (private keys, balances, amounts, raw payloads). Privacy protection includes account hashing, configurable redaction, sampling, and collector-level filtering. Node operators retain full control(not penned down in this document yet) over what data is exported. + +➡️ **[Read full Design Decisions](./02-design-decisions.md)** + +--- + +## 3. Implementation Strategy + +The telemetry code is organized under `include/xrpl/telemetry/` for headers and `src/libxrpl/telemetry/` for implementation. Key principles include RAII-based span management via `SpanGuard`, conditional compilation with `XRPL_ENABLE_TELEMETRY`, and minimal runtime overhead through batch processing and efficient sampling. + +Performance optimization strategies include probabilistic head sampling (10% default), tail-based sampling at the collector for errors and slow traces, batch export to reduce network overhead, and conditional instrumentation that compiles to no-ops when disabled. + +➡️ **[Read full Implementation Strategy](./03-implementation-strategy.md)** + +--- + +## 4. Code Samples + +Complete C++ implementation examples are provided for all telemetry components: + +- `Telemetry.h` - Core interface for tracer access and span creation +- `SpanGuard.h` - RAII wrapper for automatic span lifecycle management +- `TracingInstrumentation.h` - Macros for conditional instrumentation +- Protocol Buffer extensions for trace context propagation +- Module-specific instrumentation (RPC, Consensus, P2P, JobQueue) + +➡️ **[View all Code Samples](./04-code-samples.md)** + +--- + +## 5. Configuration Reference + +Configuration is handled through the `[telemetry]` section in `xrpld.cfg` with options for enabling/disabling, exporter selection, endpoint configuration, sampling ratios, and component-level filtering. CMake integration includes a `XRPL_ENABLE_TELEMETRY` option for compile-time control. + +OpenTelemetry Collector configurations are provided for development (with Jaeger) and production (with tail-based sampling, Tempo, and Elastic APM). Docker Compose examples enable quick local development environment setup. + +➡️ **[View full Configuration Reference](./05-configuration-reference.md)** + +--- + +## 6.

Observability Backends + +For development and testing, Jaeger provides easy setup with a good UI. For production deployments, Grafana Tempo is recommended for its cost-effectiveness and Grafana integration, while Elastic APM is ideal for organizations with existing Elastic infrastructure. + +The recommended production architecture uses a gateway collector pattern with regional collectors performing tail-based sampling, routing traces to multiple backends (Tempo for primary storage, Elastic for log correlation, S3/GCS for long-term archive). + +➡️ **[View Observability Backend Recommendations](./07-observability-backends.md)** + +--- + +## 8.

Prevents silent pass on unreachable Prometheus. - run-full-validation.sh: set REGRESSION_EXIT=2 on capture failure so the final exit code reflects it. Update exit code docs in header. - compare_to_baseline.py: extract _skip_delta helper to bring compute_delta under 80 lines. Fix 0.0-as-falsy bug in abs_bound resolution (use explicit None check instead of `or`). Remove dead variable override_prefix_key. - prom_queries.py: extract _build_simple_entries and _build_job_entries to bring build_query_plan under 80 lines. Fix module docstring return type example. Use aiohttp.ClientTimeout instead of bare int. - telemetry-validation.yml: add set -euo pipefail to regression summary step; guard jq calls with -e flag and fallback; fail on missing baseline file; emit ::warning annotation when timings.json missing. - baselines/README.md: document the placeholder field. --- .github/workflows/telemetry-validation.yml | 19 +++- docker/telemetry/workload/baselines/README.md | 5 + docker/telemetry/workload/capture_timings.py | 18 ++++ .../telemetry/workload/compare_to_baseline.py | 71 ++++++------ docker/telemetry/workload/prom_queries.py | 102 +++++++++--------- .../telemetry/workload/run-full-validation.sh | 7 +- 6 files changed, 126 insertions(+), 96 deletions(-) diff --git a/.github/workflows/telemetry-validation.yml b/.github/workflows/telemetry-validation.yml index 834da6fc4ec..b44a75bac1f 100644 --- a/.github/workflows/telemetry-validation.yml +++ b/.github/workflows/telemetry-validation.yml @@ -238,16 +238,27 @@ jobs: - name: Print regression summary if: always() run: | + set -euo pipefail TIMINGS="/tmp/xrpld-validation/reports/timings.json" REGRESSION="/tmp/xrpld-validation/reports/regression-report.json" BASELINE="docker/telemetry/workload/baselines/baseline-timings.json" if [ ! -f "$TIMINGS" ]; then echo "## Regression Gate: no timings captured" >> "$GITHUB_STEP_SUMMARY" + echo "::warning::capture_timings.py did not produce timings.json — regression gate was not evaluated." exit 0 fi - IS_PLACEHOLDER=$(jq -r '.placeholder == true or (.metrics | length == 0)' "$BASELINE") + if [ ! -f "$BASELINE" ]; then + echo "## Regression Gate: baseline file missing" >> "$GITHUB_STEP_SUMMARY" + echo "::error::baselines/baseline-timings.json not found in checkout" + exit 1 + fi + + IS_PLACEHOLDER=$(jq -e -r '.placeholder == true or (.metrics | length == 0)' "$BASELINE") || { + echo "::error::Failed to parse baseline JSON" + exit 1 + } echo "## OTel Timings Regression Gate" >> "$GITHUB_STEP_SUMMARY" echo "" >> "$GITHUB_STEP_SUMMARY" @@ -263,9 +274,9 @@ jobs: cat "$TIMINGS" >> "$GITHUB_STEP_SUMMARY" echo '```' >> "$GITHUB_STEP_SUMMARY" elif [ -f "$REGRESSION" ]; then - REGR_COUNT=$(jq '.summary.regressions' "$REGRESSION") - IMPR_COUNT=$(jq '.summary.improvements' "$REGRESSION") - TOTAL=$(jq '.summary.total' "$REGRESSION") + REGR_COUNT=$(jq -e '.summary.regressions' "$REGRESSION") || REGR_COUNT=0 + IMPR_COUNT=$(jq -e '.summary.improvements' "$REGRESSION") || IMPR_COUNT=0 + TOTAL=$(jq -e '.summary.total' "$REGRESSION") || TOTAL=0 echo "| Stat | Count |" >> "$GITHUB_STEP_SUMMARY" echo "|------|-------|" >> "$GITHUB_STEP_SUMMARY" echo "| Metrics compared | $TOTAL |" >> "$GITHUB_STEP_SUMMARY" diff --git a/docker/telemetry/workload/baselines/README.md b/docker/telemetry/workload/baselines/README.md index 4f12646449c..515a3f561fe 100644 --- a/docker/telemetry/workload/baselines/README.md +++ b/docker/telemetry/workload/baselines/README.md @@ -62,6 +62,11 @@ should trace back to a real CI run so variance characteristics are preserved. } ``` +Placeholder baselines additionally include `"placeholder": true`.

No cross-node P2P context propagation or consensus tracing in the POC. ### Related Plan Documents -| Document | Relevance to POC | -| ---------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | -| [00-tracing-fundamentals.md](./00-tracing-fundamentals.md) | Core concepts: traces, spans, context propagation, sampling | -| [01-architecture-analysis.md](./01-architecture-analysis.md) | RPC request flow (§1.5), key trace points (§1.6), instrumentation priority (§1.7) | -| [02-design-decisions.md](./02-design-decisions.md) | SDK selection (§2.1), exporter config (§2.2), span naming (§2.3), attribute schema (§2.4), coexistence with PerfLog/Insight (§2.6) | -| [03-implementation-strategy.md](./03-implementation-strategy.md) | Directory structure (§3.1), key principles (§3.2), performance overhead (§3.3-3.6), conditional compilation (§3.7.3), code intrusiveness (§3.9) | -| [04-code-samples.md](./04-code-samples.md) | Telemetry interface (§4.1), SpanGuard (§4.2), macros (§4.3), RPC instrumentation (§4.5.3) | -| [05-configuration-reference.md](./05-configuration-reference.md) | rippled config (§5.1), config parser (§5.2), Application integration (§5.3), CMake (§5.4), Collector config (§5.5), Docker Compose (§5.6), Grafana (§5.8) | -| [06-implementation-phases.md](./06-implementation-phases.md) | Phase 1 core tasks (§6.2), Phase 2 RPC tasks (§6.3), quick wins (§6.10), definition of done (§6.11) | -| [07-observability-backends.md](./07-observability-backends.md) | Tempo dev setup (§7.1), Grafana dashboards (§7.6), alert rules (§7.6.3) | +| Document | Relevance to POC | +| ---------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- | +| [00-tracing-fundamentals.md](./00-tracing-fundamentals.md) | Core concepts: traces, spans, context propagation, sampling | +| [01-architecture-analysis.md](./01-architecture-analysis.md) | RPC request flow (§1.5), key trace points (§1.6), instrumentation priority (§1.7) | +| [02-design-decisions.md](./02-design-decisions.md) | SDK selection (§2.1), exporter config (§2.2), span naming (§2.3), attribute schema (§2.4), coexistence with PerfLog/Insight (§2.6) | +| [03-implementation-strategy.md](./03-implementation-strategy.md) | Directory structure (§3.1), key principles (§3.2), performance overhead (§3.3-3.6), conditional compilation (§3.7.3), code intrusiveness (§3.9) | +| [04-code-samples.md](./04-code-samples.md) | Telemetry interface (§4.1), SpanGuard (§4.2), macros (§4.3), RPC instrumentation (§4.5.3) | +| [05-configuration-reference.md](./05-configuration-reference.md) | xrpld config (§5.1), config parser (§5.2), Application integration (§5.3), CMake (§5.4), Collector config (§5.5), Docker Compose (§5.6), Grafana (§5.8) | +| [06-implementation-phases.md](./06-implementation-phases.md) | Phase 1 core tasks (§6.2), Phase 2 RPC tasks (§6.3), quick wins (§6.10), definition of done (§6.11) | +| [07-observability-backends.md](./07-observability-backends.md) | Tempo dev setup (§7.1), Grafana dashboards (§7.6), alert rules (§7.6.3) | --- @@ -137,7 +137,7 @@ -

charset=UTF-8 Content-Transfer-Encoding: 8bit Add span discard mechanism that drops unwanted spans before they enter the batch export queue, saving both network bandwidth and storage. FilteringSpanProcessor is a custom SpanProcessor decorator that wraps BatchSpanProcessor. SpanGuard::discard() sets a thread-local flag (tl_discardCurrentSpan) before calling Span::End(). The OTel SDK calls OnEnd() synchronously on the same thread, where the flag is checked and cleared to drop the span. New file: DiscardFlag.h — zero-dependency header for the thread-local flag, avoiding transitive include bloat from Telemetry.h.

Key design choices adapted from the original Phase 4 implementation to the new SpanGuard factory pattern introduced in Phase 3: - Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs (consensus round spans share trace_id across validators via ledger hash) - Add SpanGuard::addEvent() overload with key-value attribute pairs (used for dispute.resolve events during position updates) - Add ConsensusSpanNames.h with compile-time span name constants following the colocated *SpanNames.h pattern from Phase 3 - Add consensusTraceStrategy config option ("deterministic"/"attribute") for cross-node trace correlation strategy selection - Use SpanGuard::linkedSpan() for follows-from relationships between consecutive rounds and cross-thread validation spans - Use SpanGuard::captureContext() for thread-safe context propagation from consensus thread to jtACCEPT worker thread Spans produced: consensus.round, consensus.proposal.send, consensus.ledger_close, consensus.establish, consensus.update_positions, consensus.check, consensus.accept, consensus.accept.apply, consensus.validation.send, consensus.mode_change Co-Authored-By: Claude Opus 4.6 (1M

The deterministic trace_id from the ledger hash is the key feature enabling cross-node correlation — replacing it broke correlation on all rounds after the first. Also: use thread_local mt19937 for hashSpan() span IDs (same fix as phase-3 txSpan), add Doxygen to establish tracing method declarations in Consensus.h, and update SpanGuard.h diagram with hashSpan/addEvent.

All consensus tracing uses + `SpanGuard` factory methods (`span()`, `hashSpan()`, `linkedSpan()`) and direct + method calls (`setAttribute()`, `addEvent()`). This avoids macro control-flow + issues and is cleaner than the planned approach. - **Separation of concerns**: All non-trivial telemetry code extracted to private helpers (`startRoundTracing`, `createValidationSpan`, `startEstablishTracing`, `updateEstablishTracing`, `endEstablishTracing`). Business logic methods contain - only single-line `#ifdef` blocks calling these helpers. + single-line calls to these helpers. - **Thread safety**: `createValidationSpan()` runs on the jtACCEPT worker thread. Instead of accessing `roundSpan_` across threads, a `roundSpanContext_` snapshot (lightweight `SpanContext` value type) is captured on the consensus thread in `startRoundTracing()` and read by `createValidationSpan()`. The job queue provides the happens-before guarantee. -- **Macro safety**: `XRPL_TRACE_ADD_EVENT` uses `do { } while (0)` to prevent - dangling-else issues. +- **No `#ifdef` guards**: Span members use `std::optional` and `SpanContext` + which have no-op implementations when telemetry is disabled. No `#ifdef XRPL_ENABLE_TELEMETRY` + guards needed around members or includes. +- **No `getTelemetry()` adaptor method**: `SpanGuard::span()` is a static factory that + internally checks telemetry state, so `Consensus.h` doesn't need adaptor access + for span creation. Only `RCLConsensus::Adaptor` accesses `app_.getTelemetry()` directly. - **Config validation**: `consensus_trace_strategy` is validated to be either `"deterministic"` or `"attribute"`, falling back to `"deterministic"` for unrecognised values.

Key design choices adapted from the original Phase 4 implementation to the new SpanGuard factory pattern introduced in Phase 3: - Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs (consensus round spans share trace_id across validators via ledger hash) - Add SpanGuard::addEvent() overload with key-value attribute pairs (used for dispute.resolve events during position updates) - Add ConsensusSpanNames.h with compile-time span name constants following the colocated *SpanNames.h pattern from Phase 3 - Add consensusTraceStrategy config option ("deterministic"/"attribute") for cross-node trace correlation strategy selection - Use SpanGuard::linkedSpan() for follows-from relationships between consecutive rounds and cross-thread validation spans - Use SpanGuard::captureContext() for thread-safe context propagation from consensus thread to jtACCEPT worker thread Spans produced: consensus.round, consensus.proposal.send, consensus.ledger_close, consensus.establish, consensus.update_positions, consensus.check, consensus.accept, consensus.accept.apply, consensus.validation.send, consensus.mode_change Co-Authored-By: Claude Opus 4.6 (1M

The deterministic trace_id from the ledger hash is the key feature enabling cross-node correlation — replacing it broke correlation on all rounds after the first. Also: use thread_local mt19937 for hashSpan() span IDs (same fix as phase-3 txSpan), add Doxygen to establish tracing method declarations in Consensus.h, and update SpanGuard.h diagram with hashSpan/addEvent.

All consensus tracing uses + `SpanGuard` factory methods (`span()`, `hashSpan()`, `linkedSpan()`) and direct + method calls (`setAttribute()`, `addEvent()`). This avoids macro control-flow + issues and is cleaner than the planned approach. - **Separation of concerns**: All non-trivial telemetry code extracted to private helpers (`startRoundTracing`, `createValidationSpan`, `startEstablishTracing`, `updateEstablishTracing`, `endEstablishTracing`). Business logic methods contain - only single-line `#ifdef` blocks calling these helpers. + single-line calls to these helpers. - **Thread safety**: `createValidationSpan()` runs on the jtACCEPT worker thread. Instead of accessing `roundSpan_` across threads, a `roundSpanContext_` snapshot (lightweight `SpanContext` value type) is captured on the consensus thread in `startRoundTracing()` and read by `createValidationSpan()`. The job queue provides the happens-before guarantee. -- **Macro safety**: `XRPL_TRACE_ADD_EVENT` uses `do { } while (0)` to prevent - dangling-else issues. +- **No `#ifdef` guards**: Span members use `std::optional` and `SpanContext` + which have no-op implementations when telemetry is disabled. No `#ifdef XRPL_ENABLE_TELEMETRY` + guards needed around members or includes. +- **No `getTelemetry()` adaptor method**: `SpanGuard::span()` is a static factory that + internally checks telemetry state, so `Consensus.h` doesn't need adaptor access + for span creation. Only `RCLConsensus::Adaptor` accesses `app_.getTelemetry()` directly. - **Config validation**: `consensus_trace_strategy` is validated to be either `"deterministic"` or `"attribute"`, falling back to `"deterministic"` for unrecognised values.

Key design choices adapted from the original Phase 4 implementation to the new SpanGuard factory pattern introduced in Phase 3: - Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs (consensus round spans share trace_id across validators via ledger hash) - Add SpanGuard::addEvent() overload with key-value attribute pairs (used for dispute.resolve events during position updates) - Add ConsensusSpanNames.h with compile-time span name constants following the colocated *SpanNames.h pattern from Phase 3 - Add consensusTraceStrategy config option ("deterministic"/"attribute") for cross-node trace correlation strategy selection - Use SpanGuard::linkedSpan() for follows-from relationships between consecutive rounds and cross-thread validation spans - Use SpanGuard::captureContext() for thread-safe context propagation from consensus thread to jtACCEPT worker thread Spans produced: consensus.round, consensus.proposal.send, consensus.ledger_close, consensus.establish, consensus.update_positions, consensus.check, consensus.accept, consensus.accept.apply, consensus.validation.send, consensus.mode_change Co-Authored-By: Claude Opus 4.6 (1M

The deterministic trace_id from the ledger hash is the key feature enabling cross-node correlation — replacing it broke correlation on all rounds after the first. Also: use thread_local mt19937 for hashSpan() span IDs (same fix as phase-3 txSpan), add Doxygen to establish tracing method declarations in Consensus.h, and update SpanGuard.h diagram with hashSpan/addEvent.

Business logic methods contain - only single-line `#ifdef` blocks calling these helpers. + single-line calls to these helpers. - **Thread safety**: `createValidationSpan()` runs on the jtACCEPT worker thread. Instead of accessing `roundSpan_` across threads, a `roundSpanContext_` snapshot (lightweight `SpanContext` value type) is captured on the consensus thread in `startRoundTracing()` and read by `createValidationSpan()`. The job queue provides the happens-before guarantee. -- **Macro safety**: `XRPL_TRACE_ADD_EVENT` uses `do { } while (0)` to prevent - dangling-else issues. +- **No `#ifdef` guards**: Span members use `std::optional` and `SpanContext` + which have no-op implementations when telemetry is disabled. No `#ifdef XRPL_ENABLE_TELEMETRY` + guards needed around members or includes. +- **No `getTelemetry()` adaptor method**: `SpanGuard::span()` is a static factory that + internally checks telemetry state, so `Consensus.h` doesn't need adaptor access + for span creation. Only `RCLConsensus::Adaptor` accesses `app_.getTelemetry()` directly. - **Config validation**: `consensus_trace_strategy` is validated to be either `"deterministic"` or `"attribute"`, falling back to `"deterministic"` for unrecognised values.

OTLP uses HTTP/gRPC with retries, binary protobuf encoding, and connection-level flow control. + +3. **Fixes the `|m` wire format issue** — The `StatsDMeterImpl` uses non-standard `|m` StatsD type that the OTel StatsD receiver silently drops. Native OTel counters eliminate this problem entirely (Phase 6 Task 6.1 — DEFERRED becomes resolved). + +4. **Richer metric semantics** — OTel Metrics SDK supports explicit histogram bucket boundaries, exemplars (linking metrics to traces), resource attributes, and metric views. StatsD has no concept of these. + +5. **Removes infrastructure dependency** — No more StatsD receiver needed in the OTel Collector. One less receiver to configure, monitor, and debug. Simplifies the collector YAML. + +6. **Metric-to-trace correlation** — OTel metrics and traces share the same resource attributes (service.name, service.instance.id). Grafana can link from a metric spike directly to the traces that caused it — impossible with StatsD-sourced metrics. + +7. **Production-grade export** — OTel's `PeriodicMetricReader` provides configurable export intervals, batch sizes, timeout handling, and graceful shutdown — all built into the SDK rather than hand-rolled in `StatsDCollectorImp`. + +#### What We Lose + +1. **StatsD ecosystem compatibility** — Operators using external StatsD-compatible backends (Datadog Agent, Graphite, Telegraph) will need to switch to OTLP-compatible backends or keep `server=statsd` as a fallback. + +2. **Simplicity of UDP** — StatsD's UDP fire-and-forget model is dead simple and has zero connection management. OTLP/HTTP requires a TCP connection, TLS negotiation (in production), and retry logic. The OTel SDK handles this, but it's more moving parts. + +3. **Slightly higher memory** — OTel SDK maintains internal aggregation state for metrics before export. StatsD just formats and sends strings. Expected overhead: ~1-2 MB additional for metric state. + +4. **Dependency on OTel C++ Metrics SDK stability** — The Metrics SDK is GA since 1.0 and on version 1.18.0, but it's less battle-tested than the tracing SDK in the C++ ecosystem. + +#### Decision + +The gains (unified pipeline, delivery guarantees, metric-trace correlation, simpler collector config) significantly outweigh the losses. `StatsDCollector` is retained as a fallback via `server=statsd` for operators who need StatsD ecosystem compatibility during the transition period. + +### Architecture + +#### Class Hierarchy (after Phase 7) + +``` +beast::insight::Collector (abstract interface — unchanged) + | + +-- StatsDCollector (existing — retained as fallback, deprecated) + | +-- StatsDCounterImpl -> StatsD |c over UDP + | +-- StatsDGaugeImpl -> StatsD |g over UDP + | +-- StatsDMeterImpl -> StatsD |m over UDP (non-standard) + | +-- StatsDEventImpl -> StatsD |ms over UDP + | +-- StatsDHookImpl -> 1s periodic callback + | + +-- NullCollector (existing — unchanged, used when disabled) + | +-- NullCounterImpl -> no-op + | +-- NullGaugeImpl -> no-op + | +-- NullMeterImpl -> no-op + | +-- NullEventImpl -> no-op + | +-- NullHookImpl -> no-op + | + +-- OTelCollector (NEW — Phase 7) + +-- OTelCounterImpl -> otel::Counter + +-- OTelGaugeImpl -> otel::ObservableGauge + +-- OTelMeterImpl -> otel::Counter + +-- OTelEventImpl -> otel::Histogram + +-- OTelHookImpl -> 1s periodic callback (same pattern) +``` + +#### Data Flow (after Phase 7) + +```mermaid +graph LR + subgraph xrpldNode["xrpld Node"] + A["Trace Macros
