Disk IO Summary not working

CMK version: 2.2.0p21
OS version: Ubuntu 23.10
Affected host: Linux Server with snmp

Hi folks!

i would like to have the sensor disk summary and not the individual sensors:

For this, I created a Disk IO discovery Rule with this options:
image

But the sensors still persist.

Any ideas?

It would be good to show al little bit more of your rule - the condition is the important information. And also you should have at the resulting rules for this host.
After you created the rule you need to do a discovery on the host again.

This is the rule:

I do a complete new discovery for the effected host.
Maybe it is not working because it is via snmp?

I think it depends on the type of agent that delivers the data.
For ucd_diskio fetched with SNMP it will not work i think.
For normal agent based data the summary is the default setting.

Ok thank you, i already thought that snmp is the problem. Do you know a way to cumulate that in a sensor?

If you monitor the Linux server with the Checkmk agent, you will get the summary you are looking for out of the box.
