feat(monitoring): add monitoring stack docs + dashboard-as-code backup#7963
Conversation
…loper guide, and lifecycle workflow Closes #7962 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Greptile SummaryThis PR adds a comprehensive
Confidence Score: 3/5Documentation-only change; the targetPort bug in the service template example would silently break metrics scraping for any team that copies it verbatim. The metrics Service template example uses backend/charts/monitoring/README.md — the ServiceMonitor service template snippet (targetPort) and the troubleshooting section need correction.

targetPort in the metrics Service template points to {{ .Values.service.port }} (the main application port) instead of {{ .Values.metrics.port }} (the metrics port). If a service exposes its main traffic on port 8080 and its metrics on port 9091, Kubernetes would forward connections on the Service's port 9091 to pod port 8080 — the scrape would hit the wrong handler and likely get an HTTP 404 or non-Prometheus response, silently breaking metrics collection for any team that copies this template verbatim.

| 1. Check the pod exposes `/metrics` and returns valid Prometheus format | ||

| 4. Check Prometheus targets: `https://monitor.omi.me/` → Explore → Prometheus datasource → metric name |

| 4. Check Prometheus targets: `https://monitor.omi.me/` → Explore → Prometheus datasource → metric name | |
| 4. Check Prometheus targets: in Grafana go to `https://monitor.omi.me/` → Connections → Data Sources → Prometheus → "Explore" to query the metric, or access the Prometheus UI directly and navigate to Status → Targets to see scrape status |

| Alerting is configured through Grafana unified alerting (not Prometheus AlertManager rules directly). Alert screenshots are enabled via the Grafana image renderer. |

The dashboards/ and alerts/ subdirectories are shown in the directory tree as if they exist today, but neither is present in the repo. A developer cloning the repo and following this README would look for backend/charts/monitoring/dashboards/ and find nothing. Consider marking this section as a target layout (e.g., "Planned directory structure") or creating the directories with a .gitkeep in the same PR.
…elease names - Fix architecture diagram: Stackdriver exporter scraped by Prometheus, not feeding adapter directly - Add both external.metrics and custom.metrics.k8s.io API types (parakeet uses Pods metrics) - Fix dev Helm release name: dev-kube-prometheus-stack (not dev-omi-kube-prometheus-stack) - Clarify Grafana URLs: prod monitor.omi.me, dev monitor.omiapi.com - Fix auth secret naming: alloy-basic-auth → loki-basic-auth chain - Label scrape jobs table as custom/additional (excludes built-in targets) - Mark dashboards/ and alerts/ as proposed directories - Note parakeet adapter rules not yet merged into cluster adapter - Add helm repo add/update prerequisite Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…c-back procedure Addresses manager's 3 requirements for PR #7963: 1. Full catalog of 45 Grafana dashboards (29 bundled + 16 custom) organized by folder 2. Step-by-step workflows for creating new dashboards and updating existing ones 3. Sync-back workflow for exporting Grafana UI changes to repo (single + bulk) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…decar provisioning 1. Use exact Grafana UIDs (not truncated) in tables and sync scripts 2. Fix dashboard counts: 28 bundled + 17 custom (not 29+16) 3. Replace incomplete ConfigMap workflow with Grafana sidecar provisioning using grafana_dashboard: "1" label (matches existing kube-prometheus-stack config) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
