Description
The vmstat module determines the amount of virtual memory
in use on the host to be checked, via the vmstat command.
Examples
- To warn when free memory is less than 20000 units or at least 10000
units of swap are in use, and to generate a problem when free memory
is less than 20000 units or at least 10000 units of swap are in use:
module vmstat {
freewarn 20000
freeprob 15000
swapwarn 10000
swapprob 15000
}
Design Errors
This module currently only understands the output of vmstat
used by Linux.
