Change the SSH disk free sesnor to specifically query local drives only



We have an ongoing issue with a sensor which is an SSH disk free space sensor. Having investigated the issue is owing to stale mounts on laptops that are mounted onto it. If you log onto the server and run df command with the switch of -l it just looks at local disks. Is there a way of implementing this or the sensor being altered to exclude the mount.

The mounts are under CIFS shares, if i log onto the server and run command df -h it hangs as a result. If i do a df -l it returns straight away. 

  Having looked at the command that PRTG runs it does not use -l switch for local as this returns straight away   From the docs and link below I think the following. https://kb.paessler.com/en/topic/82626-what-command-is-used-for-ssh-disk-free-sensor    df -TP -x tmpfs -x devtmpfs -x debugfs   needs to be df -l -TP -x tmpfs -x devtmpfs -x debugfs

Hi Neil,

I'll pass this to our developers to see if it's actually intended to include share volumes or not and get back to you :) You could use this in the meantime:


Which allows you to modify the corresponding commandline according to your needs
