Percona MYSQL Memory Tuning and Monitoring

keithhubnerkeithhubner EntrantInactive User Role Beginner

This question has probably been asked 100 times but here goes. We are having strange memory issues on our percona-galera cluster. Every so often we see chunks of memory being consumed. We have extremely high spec servers (32 cores 32GB RAM) so ample capacity. What I would like to do is getting a better idea of what is consuming the memory, it could be a bad query but nothing out of the ordinary is running.

We currently have the innodb buffer set to 4GB, we originally had this as 20GB but had the same issues.

Any help or advice would be appreciated.
