At the time of writing my question the latest RabbitMQ version was 3.7.9 and latest prometheus_rabbitmq_exporter was at 184.108.40.206. So they are different.
How do I know which version of prometheus_rabbitmq_exporter is compatible with RabbitMQ?
Another question is that I have older RabbitMQ at 3.3.5, how do I find the right version of prometheus_rabbitmq_exporter?
Preferable are very simple ways, because I want to automate this.
So my script can take care of prometheus_rabbitmq_exporter for any RabbitMQ version.
