Create a new version of the API endpoint (`/v2`). This new version change the `Accept` HTTP header sent to the exporters requested (from `application/openmetrics-text` … to `text/plain`) because the Go library we use does not seems to support all OpenMetrics specificities ^1. The requests sent to the exporters contains a new HTTP header `X-Promfetcher-API-version` with the Promfetchers API version. ^1: Java actuator does respect the OpenMetrics specifications; the double quotes in the comments is not supported for example: > # HELP process_cpu_usage The \"recent cpu usage\" for the Java Virtual Machine process See also: [1]: prometheus/client_golang#829 (comment) [2]: prometheus/common#214
- v1: `application/openmetrics-text; version=0.0.1,text/plain;version=0.0.4;q=0.5,*/*;q=0.1` - v2: `text/plain; version=0.0.4; charset=utf-8`
