Metrics in Acra #

Starting from version 0.83.0, Acra supports tracking and exporting of the basic metrics of AcraServer, AcraConnector, and AcraTranslator to Prometheus.

Metrics configuration #

Command line flags #

  • --incoming_connection_prometheus_metrics_string=<url>

    URL (tcp://host:port) which will be used to expose Prometheus metrics (<URL>/metrics address to pull metrics).

Exposed metrics #

Acra can expose standard set of metric types for AcraServer, AcraConnector, and AcraTranslator. Additional metrics registration info could be found in prometheus.go files located in cmd folder for each corresponded Acra component.
