# Monitoring overlay for the Pi
|
|
|
|
These two files are the desired state of `/home/mokhtar/app/monitoring/` on the Pi
|
|
after the X1208 exporter is in place. The `.original` siblings are snapshots of
|
|
what's there right now (pulled with `ssh rpi cat ...`).
|
|
|
|
## Diff summary
|
|
|
|
**`compose.yaml`** — node-exporter service:
|
|
|
|
- Add volume `/var/lib/node-exporter/textfiles:/textfiles:ro`
|
|
- Add command flag `--collector.textfile.directory=/textfiles`
|
|
|
|
**`prometheus.yaml`** — global block:
|
|
|
|
- Add `external_labels: { host: rpi }` so metrics are tagged in Grafana Cloud
|
|
(instead of relying on the Docker service name as `instance`).
|
|
|
|
## Apply
|
|
|
|
```bash
|
|
scp compose.yaml prometheus.yaml rpi:/home/mokhtar/app/monitoring/
|
|
ssh rpi 'cd /home/mokhtar/app/monitoring && docker compose up -d'
|
|
```
|
|
|
|
This recreates the node-exporter container (~2s blip) and reloads Prometheus.
