Anyone else monitoring OEL 7 and running into swap monitoring issue:

/usr/local/nagios/libexec/check_swap -w 30% -c 20% -a
SWAP CRITICAL - 0% free (0 MB out of 0 MB) - Swap is either disabled, not present, or of zero size. |swap=0MB;0;0;0;0

but....

Code: Select all

df -Ph
Filesystem                   Size  Used Avail Use% Mounted on
/dev/mapper/vg_main-lv_root  6.0G  3.7G  2.3G  62% /
devtmpfs                     3.7G     0  3.7G   0% /dev
tmpfs                        3.7G     0  3.7G   0% /dev/shm
tmpfs                        3.7G  113M  3.6G   4% /run
tmpfs                        3.7G     0  3.7G   0% /sys/fs/cgroup
/dev/xvdb1                   497M  198M  300M  40% /boot
tmpfs                        749M     0  749M   0% /run/user/1554
tmpfs                        749M     0  749M   0% /run/user/1779

Those bottom two are the swap. How is anyone else handling this?

Hi BanditBBS,

You may need to run the swapon command for it to work. Check the output of:

cat /proc/swaps

To find swap partititions. If you see /run/user/1779 or /run/user/1554 listed you would turn them on with:

swapon /run/user/1779
swapon /run/user/1554
