Module: check_mk Branch: master Commit: 20805253fd8475692f9358e5a9788badb20fe3f4 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=20805253fd8475… Author: Lars Michelsen &lt;lm(a)mathias-kettner.de&gt; Date: Tue Apr 9 16:23:42 2019 +0200 7336 labels: New inventory script to discover generic host labels A new HW/SW inventory script has been added that works on a generic "<<<labels>>>" section. It is used to discover host labels from this section. The first agent that produces this section is the Kubernetes special agent. It creates the label sections for all kind of objects that are monitored by Check_MK. This makes Check_MK automatically import the labels configured in Kubernetes. You can now use them to filter your views, dashboards and in the future also create rules in WATO based on them.
