Dashboard - Cumulate a couple of Services possible?

CMK version: 2.0.17
OS version: Ubuntu 20.04

We have configure some checks like Linux Updates (APT Updates) for a couple of hosts. Now we get in the default dashboard about 50 warn messages for each hosts, which spams the dashboard.

Is it bossible to group those services, and collapse them or some kind of , to get a better overview?

We’ve tried to cluster those services, but that is now 100% working, because first all hosts have not the same datasources and second CMK is aswell grouping the numbers, without showing from which host.

As example in the screenshot, you see a clustered host “linux-updates” with 11 normal updates updates, those are 11 Hosts having 1 normal Update cumulated. But you dont see the hostname for which host the updates are missing.

In Custom Clustered Checks this works better, because it takes the output (text) of each host and adds this to the output with the hostname.

Do you have an idea how to solve this at it’s best ?

Kind regards,
Constantin
