The MySQL plugin for Munin was giving me a lot of issues on RHEL 6. It wasn’t working regardless of what I did, and I didn’t come across any good-enough documentation that could have helped in this situation. Putting my search skills to use, it took parts of three different solutions to get the Mysql plugin up and running in Munin.
A combination of steps from the following three posts helped me:
- Munin won’t install on CentOS 6
- Fresh install does not work with percona Server version: 5.5.38-35.2
- How to monitor servers by Munin (there is an annoying pop-up on this!)
So, if you are having any issues with Munin’s MySQL plugin in CentOS or Redhat, then one of these three solutions will definitely help you resolve it.
