# Metrics
|
|
|
The Trilium Metrics API provides comprehensive monitoring data about your Trilium instance, designed for external monitoring systems like Prometheus.
|
|
|
|
|
|
## **Endpoint**
|
|
|
|
|
|
* **URL**: `/etapi/metrics`
|
|
|
* **Method**: `GET`
|
|
|
* **Authentication**: ETAPI token required
|
|
|
* **Default Format**: Prometheus text format
|
|
|
|
|
|
## **Authentication**
|
|
|
|
|
|
You need an ETAPI token to access the metrics endpoint. Get one by:
|
|
|
|
|
|
```
|
|
|
# Get an ETAPI token
|
|
|
curl -X POST http://localhost:8080/etapi/auth/login \
|
|
|
-H "Content-Type: application/json" \
|
|
|
-d '{"password": "your_password"}'
|
|
|
|

|
|
- job_name: 'trilium'
|
|
|
static_configs:
|
|
|
- targets: ['localhost:8080']
|
|
|
metrics_path: '/etapi/metrics'
|
|
|
bearer_token: 'YOUR_ETAPI_TOKEN'
|
|

|
## **Grafana Dashboard**
|
|
|
|
|
|
<figure class="image"><img style="aspect-ratio:2594/1568;" src="1_Metrics_image.png" width="2594" height="1568"></figure>
|
|
|
|
|
|
You can also use the Grafana Dashboard that has been created for TriliumNext - just take the JSON from <a class="reference-link" href="Metrics/grafana-dashboard.json">grafana-dashboard.json</a> and then import the dashboard, following these screenshots:
|
|
|
|
|
|
<figure class="image"><img style="aspect-ratio:1881/282;" src="2_Metrics_image.png" width="1881" height="282"></figure>
|
|
|
|
|
|
Then paste the JSON, and hit load:
|
|
|
|
|
|
<figure class="image"><img style="aspect-ratio:1055/830;" src="Metrics_image.png" width="1055" height="830"></figure> |
