[Nagiosplug-devel] Bug in check_swap

[Voon, Ton]

Hampus,

I think you're right. Code looks like it only expects the 2.4 version of
output, ie, the first line of information. Looks like the change is to parse
for SwapCached, SwapTotal and SwapFree instead.

Thanks for the bug report - I've raised it on SF:
http://sourceforge.net/tracker/index.php?func=detail&aid=905971&group_id=298
80&atid=397597 so I don't lose sight of this. 

I'll have a go, but probably not until next week. If you can provide a
patch, I'll be happy to accept.

Ton

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
