Checkmk Werk 10040: Fix wrong core host name in events when using host name rewriting

by Lars Michelsen

ID: 10040 Title: Fix wrong core host name in events when using host name rewriting Component: Event Console Level: 2 Class: Bug fix Version: 1.7.0i1 The Event Console queries the monitoring core to find a match between the host in the core and the origin of the event. In case you used the event rewrite mechanism to change the host name, the lookup in the core was done with the original host name of the event instead of the rewritten host name.

Checkmk Werk 10041: Reduce apache memory usage + Change check parameters API

by Lars Michelsen

ID: 10041 Title: Reduce apache memory usage + Change check parameters API Component: WATO Level: 2 Class: Bug fix Version: 1.7.0i1 We recognized that the 1.6 check parameter (ruleset) plugin mechanism (which was based on classes and using the python abc module) consumed a lot more memory than the previous plugin API. The apache processes were ~50% bigger than in previous Checkmk releases which a too large growth. The problem is that the apache processes are part of a dynamic process pool which can scale from 5 to 64 processes (in the default config). When your apache processes use 130 MB of memory, this means that you would need to have ~8 GB of memory available to be able to handle high usage peaks. In such a situation a single process growth of 50% is relevant and should be avoided if possible. If you have already ported your WATO check parameter plugins to 1.6 you will now have to port it to the new mechanism. The new plugin API for registering check parameters is similar to the 1.5 API, but more explicit to make it easier to understand. For example the 'logins' check parameter declaration looks like this: C:+ from cmk.gui.i18n import _ from cmk.gui.valuespec import ( Integer, Tuple, ) from cmk.gui.plugins.wato import ( CheckParameterRulespecWithoutItem, rulespec_registry, RulespecGroupCheckParametersOperatingSystem, ) def _parameter_valuespec_logins(): return Tuple( help=_("This rule defines upper limits for the number of logins on a system."), elements=[ Integer(title=_("Warning at"), unit=_("users"), default_value=20), Integer(title=_("Critical at"), unit=_("users"), default_value=30) ], ) rulespec_registry.register( CheckParameterRulespecWithoutItem( check_group_name="logins", group=RulespecGroupCheckParametersOperatingSystem, parameter_valuespec=_parameter_valuespec_logins, title=lambda: _("Number of Logins on System"), )) C-:

Checkmk Werk 7944: Fixed handling of unfresh services

by Sven Panne

ID: 7944 Title: Fixed handling of unfresh services Component: cmc Level: 2 Class: Bug fix Version: 1.7.0i1 The 1.6.0 branch introduced a regression: When a service was detected as unfresh, the CMC terminated with a log message of the form: host name mismatch in active check result: expected 'FOO', got 'BAR' Even worse, this state was permanent: After restarting the same thing happened again, so the only way to get out of this was to remove the CMC's state file. Note that this only affected unfresh services, not hosts. The problem was caused by an internal confusion of host name and service name of the unfresh service, which has been fixed.

Checkmk Werk 7755: Jenkins: New special agent to query jenkins instances

by Ronny Bruska

ID: 7755 Title: Jenkins: New special agent to query jenkins instances Component: Checks & agents Level: 2 Class: New feature Version: 1.6.0b4 Special agent to monitor job and build states of a jenkins instance. Beside the state of the job it gives informations about the job score and the time since the last successful build. It also outputs informations about the last build, like the time the build was triggered, the build id, duration and result. For performance reasons, the number of recognized jobs is limited to three nested folder levels.
