Checkmk Werk 12907: check_mk_agent: Fix issues with systemd

by Moritz Kiemer

ID: 12907 Title: check_mk_agent: Fix issues with systemd Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 When deploying the checkmk agent on systemd based systems, users often encountered problems when hitting the limit of 3 connections per source (the monitoring server in this case). In addition the real time checks would not work for the same reason. This was due to systemd not terminating the connection until all child processes started by the agent had completed, including the started updates of the cached plugins, which were meant to be executed asynchronously. This is solved by adding a second service to checkmks systemd units: <tt>check-mk-agent@.service</tt>: The preexisting service. It is triggered by a remote connection of the monitoring server to the socket. This service no longer triggers the asynchronous jobs. It only outputs the available results. <tt>check-mk-agent-async.service</tt>: The new service. It consists of an agent process kept running in the background. It checks every 60 seconds wether new asynchronous jobs need to be started, to update the caches for cached plugins, and (if configured) run the real time checks. The created monitoring data is stored on disk. The (preexisting) agent process triggered by the socket will then output the prepared cached information.

Checkmk Werk 12848: Fix remote host renaming timeouts in distributed setups

by Lars Michelsen

ID: 12848 Title: Fix remote host renaming timeouts in distributed setups Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 Renaming hosts in general is already executed in a background job to prevent timeouts. But in distributed setups, when renaming a host on a remote site, a longer taking renaming could result in timeout errors. Errors like this could appear: C+: MKAutomationException: Got invalid data: Your request timed out after 110 seconds. This issue may be related to a local configuration problem or a request which works with a too large number of objects. But if you think this issue is a bug, please send a crash report. C-: With this change also the remote actions are executed asynchronously in a background job and as a result will not result in a timeout anymore.

Checkmk Werk 13072: API: addition of downtime management in distributed monitoring setup

by Wontek Hong

ID: 13072 Title: API: addition of downtime management in distributed monitoring setup Component: Core & setup Level: 1 Class: New feature Version: 2.1.0i1 In the previous version, the API allowed to only manage downtimes in a non distributed monitoring setup. This werk resolves this restriction and allows the user to equally handle downtimes in a distributed environment.

Checkmk Werk 13025: make `cmk --snmptranslate` more robust

by Benedikt Seidl

ID: 13025 Title: make `cmk --snmptranslate` more robust Component: Site Management Level: 1 Class: Bug fix Version: 2.1.0i1 Before this werk it was possible that <tt>cmk --snmptranslate</tt> would crash if the oids to translate where to long. The oids where fed to snmptranslate as arguments and there is a limit for the number of characters. If this limit was exceeded by too long oids, <tt>cmkd --snmptranslate</tt> would stop without an error and needed to be killed. With this fix the oids are fed to snmptranslate via stdin. This reduced the time to process a walk with 137379 lines from 3 minutes 35 seconds to 2.4 seconds. As the general speed is now much better, the status output was removed.
