I use plugins to supervise more than 200 virtual machines in REHL5 and CentOS5.
The plugins allow ot generate high quality graphics performance.

The option "check_readonlyfs" allows you to quickly see the virtual machine failed during the loss of a SAN storage path.
Thank you for this quality work.
