Metrics | ReJot

ReJot uses OpenTelemetry to collect metrics, which can be published to a variety of backends. See OpenTelemetry for more information. Currently, the metrics are only available in the sync command.

Metrics Exporter

To enable metrics, set the OTEL_EXPORTER_OTLP_ENDPOINT environment variable to the URL of the OpenTelemetry collector.


        export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318

Prometheus

Another option is to use Prometheus. ReJot can publish metrics on a specific port, which can be scraped by Prometheus or pushed to a Prometheus server. For more information see OpenTelemetry Documentation.

Push based

Configure Prometheus with the OTLP receiver flag, and point ReJot to the Prometheus server.


        export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:9090/api/v1/otlp

Pull based

Configure Prometheus to scrape ReJot’s metrics endpoint, which is enabled by the setting REJOT_METRICS_PORT.


        export REJOT_METRICS_PORT=9464

Then configure Prometheus to scrape ReJot’s metrics endpoint:


        scrape_configs:
  - job_name: rejot-cli
    scrape_interval: 5s
    static_configs:
      - targets: [localhost:9464]
