# Phase 5 — Incident & Deliverable Log

## P5-12 — Weekly Health Digest (2026-05-16)

**Deliverable:** `monitoring/weekly-health-digest.sh`
**Deployed to:** media-server (192.168.99.183) at `~/ansible/scripts/weekly-health-digest.sh`
**Schedule:** `/etc/cron.d/weekly-health-digest` — Monday 07:00 CDT

### What the digest covers

Lightweight drift-catcher. Runs read-only checks each Monday and posts a single concise message to the **ntfy `health-digest` topic** (dedicated topic — not grafana-alerts, not prometheus-alerts).

| Check | Method |
|-------|--------|
| PVE cluster reachable | Ping beast node-exporter |
| Prometheus targets all up | `up{job="node-exporter"}` query — known-persistent down (.227/.100) suppressed |
| Grafana/Prometheus firing alerts | `/api/v1/alerts` — PrometheusTargetDown/NodeDown suppressed (covered above) |
| PBS backup freshness | `backup_status` textfile metric |
| PBS ZFS pools imported | `zfs_pool_present` textfile metric (usb1-zfs, usb2-zfs) |
| Filesystem >85% (all nodes) | Prometheus node_filesystem query |
| ZFS pools ONLINE (cluster-wide) | `node_zfs_zpool_state` for degraded/faulted/suspended/unavail |
| Docker containers unhealthy/restarting | `docker ps` on media-server (known-unhealthy `immich_machine_learning` suppressed) |
| TLS cert expiry <21 days | Live openssl check on 6 representative domains |

### What the digest does NOT do

- Does NOT replace the quarterly full health check sweep.
- Does NOT check HAOS internals, Frigate camera counts, Coral inference times, or Authelia error rates.
- Does NOT check docker-node01/02 containers directly (no Docker API exposed).
- Does NOT verify Keepalived MASTER/BACKUP state.
- Does NOT check PBS datastore GC/verify schedules in detail.

These areas require a human-run full sweep (see `~/ansible/reports/health-check-*.md`).

### ntfy subscription

Subscribe ntfy client to topic `health-digest` on `192.168.99.198:8095`.
Same procedure as the `zfs-health` topic added in Phase 4D.

### Break-test result (2026-05-16 08:54 CDT)

Script ran successfully. Delivery confirmed on `health-digest` topic. Correctly flagged:
- **PBS ZFS pools MISSING** (usb1-zfs + usb2-zfs — INC-001 + new usb2-zfs failure) ✓
- **Grafana FIRING** (ContainerMemoryNearLimit, SwapHighWarning) ✓
- All healthy checks reported OK ✓
- Known-down nodes (.227 P5-10, .100 HAOS) correctly suppressed ✓
