Check some values from the vmstat output.
Only one value is checked at once, so is present in the performance data.
The checked value is common between GNU/Linux and AIX hosts. As an example, "in" matches the "bi" column on GNU/Linux hosts and the "fi" column on AIX hosts.
Usage: check_vmstat.sh -w -c [-v ] [-d ]
-w/--warning Warning threshold.
-c/--critical Critical threshold.
-v/--value Value monitored. Default is "wa" (IOWait) Supported values are: wa,in,out
- wa : CPU IO Wait % (wa)
- in : blk/s in on Linux (bi), file page-ins/s on AIX (fi)
- out : blk/s out on Linux (bo), file page-outs/s on AIX (fo)
-d/--delay Total delay in second. Probes are done every second. So a delay of N means that the returned value is an average on N probes. Default is 5.
