PMM-15308 Expect trimmed dashboard panel titles

[claude]

Failures fixed (investigator)

• source: Percona-Lab/pmm-submodules PR #4525 — run https://github.com/Percona-Lab/pmm-submodules/actions/runs/31632930410, check E2E / Percona Server for MySQL UI integration tests / e2e tests: @pmm-ps-integration
• blocked-on: PMM-15308 Trim whitespace from dashboard titles pmm#5767 — DO NOT MERGE until that PR lands; these tests now expect titles that don't exist on main yet.
• tests:
  • e2e_tests/tests/dashboards/mysql/mysqlDashboards.test.ts:77 — PMM-T324 Verify MySQL - MySQL User Details dashboard / @pmm-ps-integration
  • e2e_tests/tests/dashboards/mysql/mysqlDashboards.test.ts:130 — PMM-T430 Verify metrics on MySQL Group Replication Summary Dashboard / @pmm-ps-integration

What failed

Both tests failed in Dashboards.verifyMetricsPresent (pages/dashboards/dashboards.page.ts:160) — the panel titles rendered by the FB server no longer match the expected lists:

Expected: ArrayContaining [" ", "Active Users", "Lost Connections", …]
Received: ["Active Users", "Lost Connections", "Users Activity", …]

Root cause — the FB trims whitespace from dashboard titles

PR #4525 is the feature build for percona/pmm#5767 (PMM-15308), which strips leading/trailing whitespace from 39 dashboard titles. Three of the trimmed titles were hard-coded with their whitespace in pmm-qa's expected-panel lists:

Dashboard	Title on main	Title in the FB build
MySQL Group Replication Summary	"Applied Transactions "	"Applied Transactions"
MySQL Group Replication Summary	"Sent Transactions "	"Sent Transactions"
MySQL Group Replication Summary	"Rolled Back Transactions "	"Rolled Back Transactions"
MySQL User Details	" " (spacer text panel)	""
HAProxy Instance Summary	"Aborted Data Transfers "	"Aborted Data Transfers"

Read back from the running FB server (/graph/api/dashboards/uid/mysql-group-replicaset-summary, …/uid/mysql-user), the titles are trimmed exactly as the diff says.

For MySQL User Details the panel is a title-less spacer: with title: "" Grafana renders no title text at all, so the panel contributes nothing to allTextContents() — asserting '' would be meaningless, so the entry is dropped rather than emptied.

Aborted Data Transfers is the same class of stale expectation but under @pmm-ps-pxc-haproxy-integration, which the FB suite doesn't run — it runs in the daily e2e-tests-matrix.yml, so without this it would go red the day #5767 merges. Fixed here in the same commit.

Verification

Throwaway Linode VM, PMM Server perconalab/pmm-server-fb:PR-4525-94197ef (the exact image the failing run used), client tarball pmm-client-PR-4525-94197ef.tar.gz, pmm-framework --database ps,SETUP_TYPE=replication,MY_ROCKS=true --database ps,SETUP_TYPE=gr,QUERY_SOURCE=slowlog — same WIZARD_ARGS as the failing job.

Test	pmm-qa main	this branch
PMM-T324 MySQL User Details	✘ failed (same expected/received as CI)	✓ passed
PMM-T430 Group Replication Summary	✘ failed (same expected/received as CI)	✓ passed
PMM-T2029, PMM-T2079 (same spec)	✓	✓
Rest of @pmm-ps-integration	—	9 passed, 1 environmental failure (below)

PMM-T2030 - Verify QAN for PS Replica Instance failed on the repro VM on both main and this branch (QAN showed no data — the replication setup on this box never generated replica query load), and passed in the CI run. Environmental, not related to this change, which only edits three panel-name lists.

@pmm-ps-pxc-haproxy-integration was not exercised (no HAProxy/PXC setup on the repro box); the HAProxy line is verified against the FB dashboard JSON only, so the next e2e-tests-matrix.yml run after #5767 merges is what confirms it end to end.

Pre-existing, untouched: npx tsc --noEmit reports the same 4 errors in tests/dashboards/valkey/valkeyDashboards.test.ts before and after this change. ESLint is clean on the three edited files.

Other red in that FB run (triaged, not fixed here)

• @pmm-psmdb-arbiter-integration and CLI / Integration / PSMDB Shard 8.x — both died in setup with exec: "mgodatagen": executable file not found in $PATH after a transient curl: (22) … 503 while building the psmdb image. Already covered by open PRs Fail the PSMDB image build when mgodatagen install fails #1172 / Fail the psmdb-pbm image build when a download fails #1171.
• Helm tests and @pmm-psmdb-replica-integration — failed in the triggering run, passed in the re-dispatched run on the same commit. Flaky.

Follow-up

Convert from draft to ready once percona/pmm#5767 merges.

The legacy CodeceptJS osNodesOverview.metrics list (codeceptjs-e2e/tests/pages/dashboardPage.js) also carries untrimmed Nodes Overview titles, but nothing asserts that list (only clearUrl is used), so it is left alone.
