# Dashboards

> Grafana dashboards for ONR access logs (Promtail + Loki).

ONR ships an optional, self-contained observability stack based on Promtail + Loki + Grafana, plus a prebuilt dashboard for access logs.

## Start the stack

```bash theme={null}
cd deploy/observability
docker compose up -d
```

## Access

* Grafana: `http://localhost:3001` (default: `admin/admin`)
* Loki API: `http://localhost:3100`

## Auto provisioning

This stack provisions everything on startup:

* Grafana datasource `Loki` (uid: `loki`)
* Dashboard `ONR Access Log Overview` in folder `ONR`

No manual datasource/dashboard import is required.

## Log source

The default Promtail config reads access logs from:

`logs/access.log`

## Labels and cardinality

Promtail extracts structured fields (via `logfmt`) from the `kv` portion of ONR access logs, then promotes a small set of fields to Loki labels.

Default labels include:

* `status`, `method`, `provider`, `api`, `appname`

Keep label cardinality low. Avoid turning high-cardinality fields (for example `request_id`) into labels.

## Stop

```bash theme={null}
cd deploy/observability
docker compose down
```
