If I remember correctly the check_disk plug-in can only be used for checking
devices with filesystems on them.
I would suggest that you resort to the check_swap plug-in instead.
e.g.
# /usr/lib64/nagios/plugins/check_swap -h
check_swap (nagios-plugins 1.4.9) 1.59

Betreff: Monitoring SwapSpace on SLES systems
Hi,
I have a question regarding monitoring of swap files / swap partitions on Linux
servers.
I'd like to get information about swap files / swap partitions via the
check_disk command.
Like shown in the example below there exists a swap partition on the server as
/dev/sda2:
[cid:image001.gif@01D23C1A.38B2E4B0]
But when trying to monitor this partion via check_disk the output is:
[cid:image002.gif@01D23C1A.38B2E4B0]
Is there any error in the syntax and is it possible in general to get
information about the (physical) usage of swap files / partitions via
check_disk or does this command not support these kind of files / partitions ?
Do I have any other options to get the required information with one of the
Nagios plugins ?
Thanks in advance for your help.
Kind regards
Frank Schweitzer
