Prometheus API

It is possible to use /api/v1/metrics REST API endpoint to read all metrics exposed to Prometheus or to any tool that is compatible with it.

API related metrics

There are a set of metrics provieded by insights-operator-utils library, all of them related with the API usage. These are the API metrics exposed:

1. api_endpoints_requests the total number of requests per endpoint
2. api_endpoints_response_time API endpoints response time
3. api_endpoints_status_codes a counter of the HTTP status code responses returned back by the service

Additionally it is possible to consume all metrics provided by Go runtime. There metrics start with go_ and process_ prefixes.

Metrics namespace

As explained in the configuration section of this documentation, a namespace can be provided in order to act as a prefix to the metric name. If no namespace is provided in the configuration, the metrics will be exposed as described in this documentation.
