Comparison with official RabbitMQ exporter (3.8)

[rgarrigue]

Hi

Seems RabbitMQ now ships their own exporter. Can you explain add a comparison in the README to help people choose between the two ?

Best regards,

From my experience (as for today) official Prometheus plugin lacks some features this exporter provides, specifically ability to skip collecting some metrics. In the official plugin you have 2 choices either aggregated metrics or per-object, and no option to skip unwanted metrics.

On the other hand, official plugin provides erlang VM metrics, which is important as well. So I use them both. In official plugin I've disabled per-object metrics and use it only to collect erlang related metrics, for everything else I use this exporter.

Hope this helps.

In recent RabbitMQ versions, the native Prometheus plugin provides another endpoint: /metrics/detailed. It allows to explicitly query only selected metrics from selected vhosts:
