!!! warning "Experimental feature"
|
|
This feature was added in v1.0.4 and is still considered experimental. If you notice any strange behavior, please raise
|
|
a ticket in the repository issues.
|
|
|
|
Metrics can be used to track how Watchtower behaves over time.
|
|
|
|
To use this feature, you have to set an [API token](arguments.md#http-api-token) and [enable the metrics API](arguments.md#http-api-metrics),
|
|
as well as creating a port mapping for your container for port `8080`.
|
|
|
|
The metrics API endpoint is `/v1/metrics`.
|
|
|
|
## Available Metrics
|
|
|

|
|
| `watchtower_containers_scanned` | Gauge | Number of containers scanned for changes by watchtower during the last scan |
|
|
| `watchtower_containers_updated` | Gauge | Number of containers updated by watchtower during the last scan |
|
|
| `watchtower_containers_failed` | Gauge | Number of containers where update failed during the last scan |
|
|
| `watchtower_scans_total` | Counter | Number of scans since the watchtower started |

## Example Prometheus `scrape_config`
|
|
|
|
```yaml
|
|
scrape_configs:
|
|
- job_name: watchtower
|
|
scrape_interval: 5s
|
|
metrics_path: /v1/metrics
|
|
bearer_token: demotoken
|
|
static_configs:
|
|
- targets:

Replace `demotoken` with the Bearer token you have set accordingly.

## Demo
