Prometheus metrics #

Prometheus metrics are exposed on /metrics.

As we use the default registry of the Prometheus GO client library, Go runtime metrics and process metrics are also exposed.

Specific metrics :

wtf_go_info:

Information about wtf-go build.
Labels:

• revision: the revision identifier for the current commit or checkout.
• revision_time: the modification time associated with vcs.revision, in RFC3339 format.
• modified: true or false indicating whether the source tree had local modifications.

wtf_go_start_date_timestamp:

The date on which the server started expressed as an UTC Unix timestamp.
