Checkmk Werk 10710: systemd: Do not mark the agent unit failed on single agent failure

ID: 10710 Title: systemd: Do not mark the agent unit failed on single agent failure Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 When the agent is queried via systemd, the socket unit creates an instance of the agent service unit template. These are named something like <tt>check-mk-agent@842-127.0.0.1:6556-127.0.0.1:33196.service</tt>. 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.
