This check measures the current usage of physical RAM and virtual memory used by processes. You can define a warning and critical level for the usage of virtual memory, not for the usage of RAM.

Check_mk lets you define levels in percentage of the physically installed RAM or as absolute values in MB. The default levels are at 150% and 200%. That means that this check gets critical if the memory used by processes is twice the size of your RAM.

See check manpage for mem.used too.

Make sure you have the statgrab binary available on the monitored machine. Under HP-UX you also need to activate the hpux_statgrab agent plugin.
