Get queue message counts from grafana

[Cihan Tunali]

Hello,

I enabled prometheus plugin and using RabbitMQ's own dashboards to visualize my environment. I want to create a dashboard to see top 10 queues with messages. To achieve this, I get metrics from /metrics/per-objects endpoint. But when I scrape it, original RabbitMQ dashboards gone mad and did not show any data. 

Is somebody do this configuration before? Any help will welcome :) Thanks.

Hi,

/metrics/per-object is not just a superset of what /metrics normally return. I'd suggest leaving /metrics as the main target for Prometheus and adding this one as the second one: /metrics/detailed\?family=queue_coarse_metrics

The standard dashboards should work in this case (because all the expected metrics will be collected from /metrics), but the second endpoint will add per-queue details on top of it:

curl -s http://localhost:15692/metrics/detailed\?family=queue_coarse_metrics | grep ^rabbitmq_detailed_queue_messages_ready
rabbitmq_detailed_queue_messages_ready{vhost="/",queue="myqq"} 75

rabbitmq_detailed_queue_messages_ready{vhost="/",queue="myqq2"} 2

Now it's just a matter of writing a PromQL query.

Best,

I added /metrics/detailed endpoint without touching /metrics one at prometheus.yml file. After this modification, existing dashboards gone mad and did not collect data. I will try to add both endpoint and I might modify existing dashboard. Thanks.

There is nothing mad about the dashboard's behaviour - it either gets the data it expects or it does not. :)

Some basic troubleshooting for Prometheus/Grafana:

* curl the prometheus endpoint to see if you get the expected metrics (curl ...:15692/metrics/...)

* check Prometheus target scraping information to see if the above endpoint is scraped successfully

* optionally, check in Prometheus UI, that you can query/visualize the data

* check if you can add a simple panel to Grafana (add new and put a metric name as the query)

If nothing works - I'd start from the top. If it used to work, I'd start from the bottom of this list.

Best,
