[Nagiosplug-devel] Bug in check_swap

[Hampus Linden]

My own assumption is the bug is caused by the restructuring of /proc/meminfo
in kernel 2.6

2.4 outputs all swap info on one line as well as on separate lines.

2.4: cat /proc/meminfo  |grep -i swap
Swap: 4145455104  1544192 4143910912
SwapCached:        316 kB
SwapTotal:     4048296 kB
SwapFree:      4046788 kB

2.6: cat /proc/meminfo |grep -i swap
SwapCached:          0 kB
SwapTotal:     2097144 kB
SwapFree:      2097144 kB

Hampus,

Which version of check_swap are you using? Which OS?

Can you send the output from a check_swap -v -v -v -w 90% -c 95%?

Hi,

I have some strange behavior with check_swap and large swap slices.

[root at devapp01 /]# /usr/libexec/nrpe/check_swap -w 90% -c 95%
CRITICAL - Swap used: -2147483648% (0 out of 0)

Other usefull output:
[root at devapp01 /]# swapon -s
Filename                                Type            Size    Used
Priority
/dev/mapper/Volume00-LogVol03            partition      3248120 5876    -1

[root at devapp01 /]# free
             total       used       free     shared    buffers     cached

Thanks.
