I'm looking for a handy way to monitor the utilization of our var/lib/MySQL disk. I'd like to get an alert if the disk use is above a certain threshold. ESM has monitoring of the root partition, but not the MySQL disk. There is an "audit.archiverWarningThreshold" cluster property but setting it only causes a warning to be written in the audit log, and nobody's going to see that. It also is only watching the database usage and there are other things on the /var/lib/MySQL partition (notably ssgbin_log files) that can cause usage to grow. I'm trying to find something provided and supported before I resort to a 3rd party monitor such as Nagios. Searched the articles, etc, and could not find anything.
