How do I change scanning interval for all DEPLOYED sensors of a specific sensor type?



Hi Paessler,

I have tons of sensors and to reduce WMI load on the PRTG Probe, I need to adjust the scanning interval of certain sensors. For instance, I don't need to check free disk space every 60 seconds.

So, my question is:

How do I change the scanning interval of all deployed WMI Disk Free sensors to e.g. 5 mins?

Hi there,
thank you for your KB-Post.

Usually, the quickest way to change a setting from all sensors of a type is using the "Sensors > By Type > (Select Type)" menu.

You can then select all sensors on a page from the select all check-box on the top right side and then using the wrench icon change the settings from all sensors at once.

This process is called multi-edit, please see the manual page for more details:

You can also use some additional filters to locate all WMI/Windows-based sensors that are running in a 60s interval:

Perfect! That worked like a charm.

Now my probe is much healthier

Thank you

Hi there, could you by any chance give me a bit more info on constructing the sensor views?

I need to list all sensor types by interval however removing the WMI and Windows selectors seems to return nothing on this.

Hello Samuekl,
thank you for your reply.

To list all sensors with a scanning interval of 60 seconds, you can use the following query:


If you want to list all sensors(with no filters) you can use:


Note: The query will only return up to 500 sensors by default. This can be increased by appending &count=99999 to the query.
