Monitoring

Health Checks​

Bento serves two HTTP endpoints for health checks:

  • /ping can be used as a liveness probe as it always returns a 200.
  • /ready can be used as a readiness probe as it serves a 200 only when both the input and output are connected, otherwise a 503 is returned.

Metrics​

Bento exposes lots of metrics either to Statsd, Prometheus, Cloudwatch or for debugging purposes an HTTP endpoint that returns a JSON formatted object.

The target destination of Bento metrics is configurable from the metrics section, where it's also possible to rename and restrict the metrics that are emitted with mappings.

Tracing​

Bento also emits opentracing events to a tracer of your choice, which can be used to visualise the processors within a pipeline.
