Thanks @amandahla for your contribution. Would be nice if you can add a Kibana dashboards for the RabbitMQ module.

Hi @monicasarbu.I am new to ELK.Not sure I can ask questions here.Can u pls describe the uses adding the rabbitmq module?What all we can do? Can we see metrics of rabbitmq in Kibana dashboard ?I am bit confused here.Kibana dashboards and logstash will support rabbitmq?

@balamuralinagella Currently, with the rabbitmq module in Metricbeat you can monitor the RabbitMQ nodes, but we are planning to extend it to monitor queues, for example. The current version is not coming with a dedicated Kibana dashboard to visualize the collected metrics from RabbitMQ, but you can easily build your own Kibana dashboard.
Out of topic: Can you please use our forum for your next questions? Thanks!

Thanks @monicasarbu for clarifying. I will use forum here after.
