According to the image there is only 6.22% free on the root partition on the server.

This is likely below the CRITICAL threshold

The check_disk plugin which is generating the Alert, generates an alert when the disk is getting full and if the disk ran out of inodes which is happening on that partition as well.

If you run the following command as root

Code: Select all

df -i
It will show the amount of inodes used and if is is at 100%, then that is generating the Alert as well.

If you run this command, it will Find the highest inode count on the server and then you can see what is causing the issue.

Code: Select all

for i in /*; do echo $i; find $i |wc -l; done
