Hello

Is anyone using SSH sensors like "Disk Free" on vCSA 6.5? Looks like none of the ssh sensors are working...

I guess the problem is OS related as PRTG does not know VMware's Photon OS?

Sensor results:

{{{Result of Sensor 35840 (SSHv2).txt [INFO][30.03.2017 08:33:29] Opening Connection [INFO][30.03.2017 08:33:29] Linux Flavor has yet to be determined [INFO][30.03.2017 08:33:29] Sending command uname [INFO][30.03.2017 08:33:29] Sending EOF [INFO][30.03.2017 08:33:29] Reading PaeSSH result [INFO][30.03.2017 08:33:29] [STDOUT] Linux

What shell is used for that system? Does df basically work?

The shell is BASH, df works!

Are you using sudo or the compatibility mode within the linux credential section of the device?


Mar, 2017 - Permalink

- compatibility mode does not work (encrpytion algorithm failed) - Sudo works :-)

Thanks for your help!


Mar, 2017 - Permalink

Cool, you're welcome! :)

sudo with, without or using su does not help here - other ideas?

Hi,

Do you get the same error? What shell are you using (or better, the user you have configured)?

kind regards,

If it helps - log from a working sensor with "su" root and password on vCSA 6.5. Shell is bash:

Hi Marcel,

You could give this one a shot:
Monitoring Linux Distributions Incompatible With The SSH Disk Free Sensor

You should be able to use "df -TP -x tmpfs -x devtmpfs -x debugfs" as command.
