Werk #12782: Activate inventory for kubernetes objects
Komponente | HW/SW inventory |
Titel | Activate inventory for kubernetes objects |
Datum | 22.04.2021 |
Checkmk Edition | Checkmk Raw (CRE) |
Checkmk-Version | 2.0.0p4 2.1.0b1 |
Level | Kleine Änderung |
Klasse | Bugfix |
Kompatibilität | Kompatibel - benötigt kein manuelles Eingreifen |
A host is created for each kubernetes endpoint. On a checkmk site with disabled inventory (the default) the endpoint host does not have any services.
As Hosts without services are invalid, checkmk automatically adds a ping service which fails, because the endpoint host is created from piggyback data and ist not reachable. The error message looks like: "check_icmp: No hosts to check"
This werk adds the label "cmk/kubernetes:yes" to kubernetes related hosts, so the issue can now be fixed by creating an inventory rule that activates the inventory on kubernetes endpoint hosts:
Go to "Setup" → "HW/SW inventory rules" → "Do hardware/software inventory" → "Create rule in folder":
- "Status data inventory" → "Do status data inventory"
- "Host labels" → "has" → "cmk/kubernetes:yes"
→ Save
This werk alters the default configuration. Sites created with checkmk 2.0.0p4 or later automatically enable the inventory for kubernetes objects.
