Monitoring RabbitMQ with Prometheus

[g...@recongate.com]

I am trying to monitor my RabbitMQ pods using prometheus plugins:

https://github.com/deadtrickster/prometheus_rabbitmq_exporter

I download the RabbitMQ plugins and put them in the plugin directory (/usr/lib/rabbitmq/lib/rabbitmq_server-3.7.4/plugins), however when i use the command "rabbitmq-plugins list" i do not see them (i can see other plugins that are not for prometheus that i added).

When trying to enable the plugin this is the output i receive: {:plugins_not_found, [:prometheus]}.

RabbitMQ version: 3.7.4-management

Thanks

Also, if someone could help me out with some templates of k8s service and deployment of RabbitMQ together with the prometheus-exporter or point me to some documentation that would be great.

Was the node restarted after the plugins directory contents was changed? If not then it's a good idea.

In 3.7.x plugins that do not depend on the `rabbit` application won't appear in `rabbitmq-plugins list` output.

They can be enabled and "pre-enabled" by listing them in the enabled_plugins file. I need to check but

at best the plugin only has a transient dependency on `rabbit` at the moment:

https://github.com/deadtrickster/prometheus_rabbitmq_exporter/blob/master/Makefile#L5

This is something to notify the plugin author about. However, if the enabled_plugins file will include

the plugin it will be loaded and enabled. Which is likely why the author himself hasn't noticed the problem.

See https://groups.google.com/d/msg/rabbitmq-users/AzZxfgcsFQw/MBvBobfSBwAJ from less than a week ago.

and compare e.g. what rabbitmq-federation-management does with dependencies:

Thanks for the help, but is still haven't managed to get to work,

I tried restart the container after adding the plugin but it still does not work. 

I added the following line to the enable_plugin file:

[rabbitmq_managment,accept,prometheus,prometheus_cowboy,prometheus_httpd,prometheus_rabbitmq_exporter].

I downloaded the plugins from (and put the under /usr/lib/rabbitmq/lib/rabbitmq_server-3.7.4/plugins):

https://github.com/deadtrickster/prometheus_rabbitmq_exporter/releases/tag/v3.7.2.1

However when i run the "rabbitmq-plugins list" command I receive the following output:

WARNING - plugins currently enabled but missing: accept, prometheus, prometheus_cowboy, prometheus_httpd, prometheus_rabbitmq_exporter, rabbitmq_managment

Any ideas what else i can do?

Thanks

The message means that those plugins are in the enabled_plugins file but not in the plugins directory.

There are references to them but no actual .ez archives with the code.

I put the plugins i downloaded in the /usr/lib/rabbitmq/lib/rabbitmq_server-3.7.4/plugins directory and restarted the container. What should i do next?

Remove duplicate versions (e.g. prometheus has two, 3.4.3 and 3.4.5), make

sure the files are readable by the user (usually `rabbitmq`) and try again.

If you copied the files as root they won't be.

It wouldn't hurt to check what the plugin directory is what you expect:
