We have decided to use Check MK for monitoring. However, we are encountering some practical issues. The most important one is this: we have created two groups based on the OS (Windows and Linux), but we don’t know how to assign hosts to these groups. When adding hosts, we try to add them using labels, but it doesn’t work. Although we try to configure labels from the settings, every host we add belongs to both groups. How can I resolve this confusion?
For example, the host I added (an Ubuntu machine) appears in both groups even though I selected the correct label. How can I fix this issue? Even if I use the same label that I configured when adding the host, I can’t seem to add it to the correct host group, and I can’t establish the link between them.
Thanks .
What you show in screenshot 2 and 3 would actually assign the same labels twice to the host src-dca-netbox.
The rule in screenshot 3 would even assign the label cmk/os_family:linux to all of your hosts, because the rule has no conditions (see last box in part 3 of your screenshot).
But let’s start at the groups. You said that you “created two groups”. Please show a screenshot of where and how you did that.
Something to read along the way:
The User guide article on “Host structuring”, because it seems that is what you are currently trying to do:
General information on labels in Checkmk:
And also a video specifically on the topic of host and service groups:
