How to "Batch-Update" SNMP Disk free Sensor after reformat

Hi there,

I'm afraid that there is no automatic way to change / re-discover the serial numbers of these hard drives. Possibly the easiest way would be to pause the old sensors and to discover the sensors anew using the auto-discovery. This would keep the sensor history for later reporting purposes.

If you click on the small lock symbol in the settings of each disk, you can also manually enter the number. Be aware that this needs to be accurate so that PRTG can identify the disks.

Kind regards,

Hi, thanks for your answer. Then it is as I feared and I have to individually touch every single server (now 200, when we finished it will be 500+) when we recreate the image from scratch...

Can I somehow delete a single sensor (disk sensor) on all objects in a group so that I can batch-delete and then rescan?

And: Would a WMI-Sensor for disk space be more flexible in this regard?

Many thanks again

Daniel

Hi Daniel,

If these devices / sensors do not have a custom tag assigned, the best approach would be to create a list of sensors and sort it by type Sensors > By Type > S > SNMP Disk Free. You can then click the column name and sport it by Probe / Group Name to then use the Multi Edit function via the GUI.

I understand that this is cumbersome as changing the serial number is not an every day task which PRTG needs to regularly adopt to.

We recommend to not go for so many WMI sensors, as it's a very sluggish procedure and a bottleneck in terms of performance. For the specific disks, the name as well as the device ID are considered. You can get the values via this command:

Select
    DriveType, DeviceID, FreeSpace, Size, VolumeName
FROM
    Win32_LogicalDisk
WHERE
    DriveType=3

I cannot yet tell if this will change in the future, but you can follow these steps to request a new feature / improvement for future versions of our software: Feature Request.
