Health Checks
Benthos 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
Benthos 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 Benthos metrics is configurable from the metrics section, where it's also possible to rename and restrict the metrics that are emitted with mappings.
Tracing
Benthos also emits opentracing events to a tracer of your choice, which can be used to visualise the processors within a pipeline.
