vh 65dc586497 feat(esh-ml1): wire telemetry and monitoring; fix Dozzle's stale agent list
- Beszel: NVIDIA agent (stacks/beszel hosts/esh-ml1.yaml), hub system
  registered with Status/Disk/CPU/Memory/Temperature alerts; GPU samples
  verified (RTX 2000E Ada util, VRAM, power, temp).
- Uptime Kuma: health monitors for the TEI embed (:8001) and rerank (:8013)
  services — the sole backends behind the gateway, so the one exception to
  "seats are out of Kuma's lane". Reward seat excluded (no consumer).
- Homepage: dockerd on tcp/2375 bound to 10.0.50.80 (playbook step);
  esh-ml1-docker added to docker.yaml.
- Dozzle: agent v10.4.1 on esh-ml1. The hub's DOZZLE_REMOTE_AGENT still
  named ana-ml2's 10.250.50.54 and irv-ml1's retired 10.100.79.3; repointed
  to 10.251.50.54 / 10.6.110.50 (fv-ml1 and irv-ml1 logs were missing).
- Documented nh3-dev's Beszel agent failing on NH3 cold start (bind of an
  automounted NAS share); revived by hand, fix still open.

# Beszel fleet monitoring
Priority 2 completed 2026-09-11: pfi-postgres, esh-vm-db, pbs-ana and pbs-nh3
added with 16 alerts. Live samples verified, including both PBS datastores.
Fleet 17/18 up (known fv-ml1 outage). See `configs/beszel-agent/PRIORITY2.md`.
Hub: http://10.250.50.70:8090 (ana-docker), version 0.18.7 at the
2026-09-10 wiring. The hub also retains corviduo-dev's existing registration.
2026-09-11: five native agents added (ana-nas plus pfi-pve, nh3-pve,
esh-pve and esh-pve-nas); 13 systems total and 20 additional alert rules.
See `configs/beszel-agent/README.md`. Subsequently nh3-nas was installed via
DSM Docker and registered with four alerts (14 registrations total). Recovery
verification at 2026-09-12 01:51Z: all six priority-1 hosts up, Synology live
filesystem samples verified; fleet 13/14 up with known fv-ml1 outage.
| Host | Compose directory under `/opt/docker/compose/` | Additional filesystems |
|---|---|---|
| ana-docker | beszel | /mnt/backup |
| fv-ml1 | beszel-agent-ana | /tank, /home |
| nh3-docker | beszel-agent-nh3 | none |
| esh-docker-vm (hub name esh-vm-docker) | beszel-agent-esh | /mnt/backup, /mnt/books |
| irv-ml1 | beszel-agent-irv | /worktank, /storetank, /mnt/smithy |
| vm-esh-nas | beszel-agent-esh-nas | /mnt/books, /mnt/share, /mnt/music, /mnt/media |
| nh3-dev | beszel | /mnt/backup, /mnt/smithy |
| esh-ml1 (added 2026-09-25) | beszel | none — NVIDIA image (`hosts/esh-ml1.yaml`) for the RTX 2000E Ada |
⚠ **nh3-dev's agent was DOWN from the 2026-09-24 NH3 power recovery until
2026-09-25.** Docker could not bind `/mnt/smithy` at boot ("no such device"): since
`1cbde50` the NAS shares are automounted, and nh3-nas was not up yet. Docker does not
retry a container that fails to *create*, so `unless-stopped` never brought it back.
Started by hand. **It will recur on the next NH3 cold start** until the agent stops
depending on NAS mounts at boot. The NAS capacity is already reported by
nh3-nas's own agent, so dropping the two extra filesystems here is the simplest fix.
Open item.
Use `infra-ops@<ip>` with passwordless sudo, except vm-esh-nas:
`lkraven@10.0.50.154` has Docker access. Irvine's hub address is
`100.64.0.6`; its retired `10.100.79.3` address caused silent loss of monitoring.
## Filesystems and deployment
The canonical source is `stacks/beszel/`. Keep existing Compose project
names/directories and named volumes to preserve agent identity and history.
The deployment helper supports `DEPLOY_DEST_STACK` for legacy stack names
and `DEPLOY_SUDO=1` for root-owned directories. Example:
```sh
DEPLOY_SUDO=1 DEPLOY_DEST_STACK=beszel-agent-ana \
scripts/deploy-stack.sh infra-ops@10.251.50.54 beszel --compose
```
Agents use host-specific overrides selected by live `.env`:
```dotenv
COMPOSE_PROFILES=agent
COMPOSE_FILE=compose.yaml:hosts/fv-ml1.yaml
BESZEL_EXTRA_FS=/extra-filesystems/tank,/extra-filesystems/home
```
Docker agents need actual read-only bind mounts under `/extra-filesystems`.
`EXTRA_FILESYSTEMS=/tank` alone does not expose the host filesystem. The
overrides provide those mounts; the environment refers to the container paths.
Mounts are observed before deployment. Network filesystems provide usage, not
block-device I/O counters. Shared ZFS datasets expose their available quota,
which differs from raw pool allocation and snapshot-inclusive usage.
After deployment, validate with `docker compose config --quiet`, then
`docker compose up -d beszel-agent`; restart alone does not apply env or mounts.
The reusable playbook is `playbooks/beszel-filesystems.yaml` with `stack_dir`,
`host_name`, and `extra_fs` variables. Environment backups are kept in
`.env.before-fleet-wiring-20260910` on each host.
nh3-dev has the older `docker-compose` command; use that spelling. It also
requires the external `traefik-net` network to exist even for the agent profile.
Only the Beszel agent is started there. On other hosts, use `docker compose`.
Auth supports a hub SSH public key (`BESZEL_HUB_KEY`) or outbound token mode
(`BESZEL_TOKEN` and `HUB_URL`). Existing auth was preserved; nh3-dev uses the
hub public key. Never copy live tokens into version control.
## GPU telemetry
fv-ml1 and irv-ml1 use `henrygd/beszel-agent-nvidia:0.18.7` with NVIDIA
`utility` access to all GPUs. Both hosts already have NVIDIA Container Toolkit.
This collects per-card utilization, VRAM, temperature, and power draw without
changing the serving containers or GPU power limits. Verified hub samples
include both RTX PRO 6000 Blackwell cards, the RTX 3090, and the RTX A6000.
Power charts are actual GPU watts, not total wall power or a PSU/circuit sizing
recommendation. Other system components and workload peaks still matter.
## Homepage
The existing Docker-discovered Monitoring card carries the native Beszel
widget, version 2. No manual Beszel entry is added to services.yaml.
Leaving `systemId` unset gives the fleet overview (systems/up).
The dedicated PocketBase superuser is `beszel-monitoring@phasefinal.com`.
Its credential is stored in Vaultwarden as `ana-docker/beszel-monitoring` and
in Homepage's live `.env` as `HOMEPAGE_VAR_BESZEL_USERNAME` and
`HOMEPAGE_VAR_BESZEL_PASSWORD`. Labels contain only Homepage placeholders.
The operator's existing account was not reset.
Verify one card and its real widget response:
```sh
curl -fsS http://10.0.50.45:5100/api/services |
jq '[.[] | .services[]? | select(.name=="Beszel")] | length'
curl -fsS 'http://10.0.50.45:5100/api/services/proxy?group=Monitoring&service=Beszel&endpoint=systems&index=0' |
jq '{totalItems, systems: [.items[] | {name,status}]}'
```
## Alerts
Thirty rules cover the seven hosts above under the existing operator user:
| Condition | Threshold | Duration |
|---|---|---|
| Disk (root or any extra filesystem) | >85% | 5 minutes |
| CPU | >95% | 15 minutes |
| Memory | >90% | 10 minutes |
| Offline | down | 2 minutes |
| Temperature (fv-ml1 and irv-ml1) | >85 C | 5 minutes |
CPU thresholds are sustained-load warnings; expected long-running compute may
need tuning. GPU utilization alone is not an alarm because busy GPUs are normal.
corviduo-dev remains monitored but its alert policy was not changed.
Notification URL:
`generic://10.100.10.50:8096/beszel?disabletls=yes&template=json`
The bridge at `services/althing-alert-bridge/` forwards through `postbox` to the
**infra-ops inbox**, as the operator requested. Existing unused email delivery
was replaced with this verified route. Miranda is a later cutover, not enabled.
See that service's README for operation and recipient changes.
Acceptance on 2026-09-10: fv-ml1 Disk was temporarily lowered to 1%/1 minute;
the real alert reached althing at 15:29:45Z, thread
`01M25Z0WFDJM92GPTJQF769HJ7`. The threshold was then restored to 85%/5 minutes.
Verification uses `postbox thread`, which does not consume the inbox.
This installed configuration monitors filesystem capacity. It does not yet
wire ZFS pool degradation, SMART, scrubs, or an independent hub-down watchdog.
Those require separate follow-up; a green usage chart does not attest to pool health.
