Message Rates per Queue about prometheus_rabbitmq_exporter HOT 1 OPEN

Not sure if this project is still active.

For anyone interested, if you're using a monitoring setup such as Prometheus + Grafana, note that rabbitmq_queue_message_published_total is sufficient (or at least partially sufficient) to obtain some insight into queue performance per vhost.

Once you have the prometheus_rabbitmq_exporter setup and configured with RabbitMQ and your Prometheus config scraping (in our case) the Kubernetes pods running RabbitMQ, and Prometheus added as a data source in Grafana; you can try something along these lines in Grafana:

(1) Create a dashboard variable (what Grafana calls template variables)

Name: top_queues
Type: Query
Data source: prometheus
Refresh: On Time Range Change
Query:

query_result(topk(25, sum(rate(rabbitmq_queue_messages_published_total[${__range_s}s])) by(queue, vhost)))

Regex: .*queue="(.*?)".*
Multi-value: enabled
Include All Option: enabled

(2) Create a dashboard (or add a panel to an existing dashboard)

Use this query to power a graph or a table depending on your preference.

sum(rate(rabbitmq_queue_messages_published_total{queue=~"$top_queues"}[2m])) by (vhost, queue) * 7 / 8

Note that the * 7 / 8 helps refine the accuracy of your results (time series values) depending on your Prometheus scrape interval and other factors related to the number of samples you wish to include in your 2 minute ( [2m] ) query interval (i.e. this may need to be refined in your environment).

The visualization area in your Grafana graph/table will need some tuning as always. You might name this Grafana panel "Top 25 Queue Rates" or the like.
