SSH VMware ESX(i) Disk Sensor Error PE094



I added each one of my datastores to this sensor and all return the following error. Device is not compatible (can not parse reply data). (code PE094)

I found a similar thread that points to an issue where the name of the datastore does not match the results returned to PRTG.

Below is the data returned by this sensor when the results are directed to disk. It does look like the spaces in the name are part of the problem. However, after renaming "3PAR DataStore1" to "3PAR_DataStore1" and re-adding the sensor, i'm still getting the same error, any ideas?

obviously your command doesn't finish during the 'ShellTimeout' set up in the sensor setting (defaults to 5 sec). This can happen if you have mounted a large number of volumes from a NAS or SAN and one or some of them are answering slowly to the 'df'-command.

Please increase the ShellTimeout for these sensors.

Kind Regards
