fix(monitoring): align alert queries to dashboard panels

[beastoin]

Summary

Aligns all 53 alerting rules from PR #9554 against the two source-of-truth dashboards:

• Omi Services Overview (uid 6d3d0897, 67 panels)
• Parakeet ASR Monitoring (uid 07e4c65f, 46 panels)

Changes by file (6 files, 10 commits)

backend-integration.json — 5XX error rate alert perSeriesAligner changed from ALIGN_SUM to ALIGN_NONE (matching Panel 27 with preprocessor=rate)

backend-sync.json — Same perSeriesAligner fix (matching Panel 34). Added dashboard annotation to enqueue_failed alert.

parakeet.json — All 5 forwarding_rule_name selectors changed from exact match to regex =~".*prod-omi-parakeet.*" (matching Parakeet dashboard Panels 122/123). Panel IDs realigned.

pusher.json — Panel IDs realigned to match dashboard (77, 75, 79, 88). Label filters aligned to job="pusher-metrics" (max concurrent + degraded session). Panel 88 (per-pod) used for max() alert instead of panel 86 (aggregate sum).

resilience.json — Added dashboard annotation to LLM gateway fallback alert.

traffic-zero.json — Backend-listen pods annotation corrected: UID → Omi Services Overview, panel → 21 (Replica count). Pusher WS label aligned to job="pusher-metrics". Backend-listen LB panel realigned.

Alignment audit

All 53 rules reviewed. 13 changed paths across 6 files. All __dashboardUid__ + __panelId__ annotations verified (53 pairs, 0 missing across 19 dashboards).

Design decisions documented

• Pusher LB alerts use Prometheus-exported backend_latencies_count; dashboard uses native Stackdriver backend_request_count — closest contextual panel, not same metric
• Pusher max-concurrent uses max() (per-pod overload); panel 88 shows per-pod series (closest match)
• Backend-listen replicas_ready alert links to panel 21 (replicas) — no replicas_ready panel exists

Test plan

• JSON syntax validation: all 11 files pass json.load()
• Structural check: all rules have required fields
• Dashboard annotation verification: 53 pairs, 0 missing
• Changed expression assertions: P1-P13 all PASS
• CODEx review: 3 rounds, PR_APPROVED_LGTM
• CODEx tester: TESTS_APPROVED
• Deploy via grizzly apply and verify 0 firing false positives (mon)

Workflow checkpoints

CP0-CP9B all passed. CP9C not required (config-only, no cluster infra).

Review response — annotation alignment rationale

Addressing 3 reviewer concerns about alert-to-panel mismatches:

1. Pusher LB alerts (panels 75/77): Prometheus vs Stackdriver datasource
Alert queries use Prometheus-scraped Stackdriver metrics (stackdriver_internal_http_lb_rule_...backend_latencies_count). Dashboard panels use native Stackdriver datasource (loadbalancing.googleapis.com/...). These query the same underlying GCP metric through different Grafana datasource paths. Alerts use Prometheus for query portability. Annotation correctly links to the panel showing the same signal.

2. Pusher max concurrent (panel 86): max() vs sum() aggregation
Alert intentionally uses max() to detect single-pod overload. Panel 86 shows sum() for aggregate view. No max() panel exists in the dashboard. Panel 86 is the closest contextual match — operators can see total active connections when the per-pod threshold fires.

3. Backend-listen ready pods (panel 21): replicas_ready vs replicas
Alert uses kube_deployment_status_replicas_ready but no dashboard panel uses this metric. Panel 21 (kube_deployment_status_replicas) is the closest available — shows desired replica count. Previous annotation pointed to panel 9 (Memory usage) on an unrelated dashboard, so this is a significant improvement.

All 53 __dashboardUid__ + __panelId__ pairs verified to resolve to existing panels (0 missing).

Round 2 fixes

Fixed: Pusher max-concurrent alert annotation changed from panel 86 (sum()) to panel 88 (Pusher WS per pod — raw per-pod series). This matches the alert's max() aggregation better.

Acknowledged: Pusher LB alerts use Prometheus-exported backend_latencies_count while dashboard panels use native Stackdriver backend_request_count. These are related but technically different GCP metrics. Panels 75/77 are the closest contextual panels for the pusher LB signal — no Prometheus-query panels exist in the dashboard for this metric. Documented as closest contextual panel choice, not a same-metric claim.
