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 visualize the processors within a pipeline.
