|Component||Checks & Agents|
|Title||systemd: Do not mark the agent unit failed on single agent failure|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
When the agent is queried via systemd, the socket unit creates an instance of the agent service unit template. These are named something like email@example.com:6556-127.0.0.1:33196.service.
When one of these services failed in the past for some reason, the unit was left in a failed state and reported by the Checkmk systemd service monitoring as a failed service.
In reality such errors can occur sporadically for various reasons. However, they are usually uninteresting. For this reason, the agent is now executed in such a way that erroneous executions do not lead to a faulty unit.
