1 title: Usage of physical and virtual RAM
7 This check measures the current usage of physical RAM and
8 virtual memory used by processes. You can define a warning
9 and critical level for the usage of virtual memory,
10 {not} for the usage of RAM.
12 Check_mk lets you define levels in percentage of
13 the physically installed RAM or as absolute
14 values in MB. The default levels
15 are at 150% and 200%. That means that this check
16 gets critical if the memory used by processes
17 is twice the size of your RAM.
19 See check manpage for {mem.used} too.
21 Make sure you have the statgrab binary available on the monitored
22 machine. Under HP-UX you also need to activate the hpux_statgrab agent plugin.
25 Finds one service on every machine with statgrab: The memory used.
