⚠️ 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 and enable the metrics API, as well as creating a port mapping for your container for port 8080.
