How can I define or change the default values for a WMI volume sensor?



I would like to know how to define or change the default values for a WMI volume sensor. I know that I can change one-by-one of my WMI volume sensor values in the 'Channel-tab', but I need to set a default value that will be set for all new WMI volume sensors that I create.

Thanks a lot.

supposing that you do refer to the 'Error'- and 'Warning'-Limits, I'm afraid that these default values are hard-coded, and cannot be changed.

Best Regards.

well, I have dozen of servers and about 3 or 4 volumes in each one. I need a way to set the same default value for all these volumes of all of the servers.

I would like to know wich is the best way to do it, because do it manually one by one would be so hard.

What can you suggest for me?

Thank you very much.

As said, unfortunately, in the moment there is no other option or way to do this with WMI Volume Sensors.

Well, and is there a way to create a custom sensor and using a WMI query to monitor volumes, setting its default values and solve my problem? Thank you very much!

Such a Custom Sensor would have the same problem, as the Error-/Warning-Limits are set in 'Channels'-tab of each sensor. So you would have to go through the sensors one by one again. I am sorry for the hassle, but in the moment, it cannot be done in a different way.

As a long time mrtg user, and a big new fan of PRTG AND As someone with a lot of volumes to monitor in prtg

I'm actually quite surprised that WMI ALL thresholds are not customizable. I just ran into this on a system with a 10GB os partition that was only 9% free and found ALL SYSTMS GREEN - that's preposterous, so I modified the settings for this machine.

I'm not looking forward to fiddling with each volume one by one but it looks like that will be required.

JUST WHAT ARE the warning/error thresholds that you have chosen?

We are testing these sensors, and have found something that doesn't seem to make sense.

Can you only set Error & Warning limits as a percentage of the drive?

We have a lot of volumes that are 1 TB+ in size and to be notified when there is even 1% of the drive left isn't really useful. Is there a way to set the Error & Warning limits so the sensor changes state when there is a specific amount of free space left?

The WMI Volume sensors feature Byte-Limits. Just go to the "Channel"-Tab and select the "Byte-Channel" and enable the limits:
