Checkmk Werk 14540: service discovery: changing the documentation for the discovery mode

by Wontek Hong

ID: 14540 Title: service discovery: changing the documentation for the discovery mode Component: REST API Level: 1 Class: Bug fix Version: 2.2.0i1 The previous documentation for the service discovery mode "refresh" caused some confusion as its description was close to the GUI's "Remove all and find new" option. This werk therefore overhauls the description of the discovery mode parameter.

Checkmk Werk 14424: Interface services: Do not abort upon counter overflow

by Joerg Herbel

ID: 14424 Title: Interface services: Do not abort upon counter overflow Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Most of the interface check plugins (such as <tt>if64</tt>) are counter-based. This means that the rates shown in the service outputs are computed by Checkmk based on these counters. One property of these counters is that they may overflow and subsequently re-start from zero. When this happens, no useful rate can be computed for this check cycle. Before this werk, Checkmk aborted and did not produce any service output in this case. Now, Checkmk instead skips the metrics for which the corresponding counters overflowed, but still produces the remaining, unaffected results. Note thas this only applies to ungrouped interfaces, i.e. the vast majority of all interface services.

Checkmk Werk 14542: Interface checks: Stop producing constantly zero and potentially wrong metrics

by Joerg Herbel

ID: 14542 Title: Interface checks: Stop producing constantly zero and potentially wrong metrics Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The interface checks process a lot of different metrics (input and output bandwidth, input and output error rates, input and and output packet rates, etc.). Before this werk, for any metric not reported by a device, the interface checks returned constantly zero values. For example, for EC2 instances in AWS, the only metrics reported by the AWS special agent are input and output bandwidth. Before this werk, the interface check constantly reported zero for all packet rates in this case. This is however useless and potentially wrong in many places. Therefore, as of this werk, the interface checks only return metrics for which the corresponding device actually reports values.

by Mathias Laurin

ID: 13912 Title: Fix crash on restarting the RRDHelper Component: cmc Level: 1 Class: Bug fix Version: 2.2.0i1 The RRDHelper may need to be restarted without a full restart of the CMC.

Checkmk Werk 14288: Fix Apache error message in case site Apache is not started

by Lars Michelsen

ID: 14288 Title: Fix Apache error message in case site Apache is not started Component: Site Management Level: 1 Class: Bug fix Version: 2.2.0i1 With 2.1.0p7 and werk #14281 we changed the system Apache configuration which broke the System Apache error page that is shown to the user in case the site Apache is not running. It showed a 'Service Unavailable' message instead of the intended 'Checkmk: Site Not Started'. To apply this fix, you will have to execute <tt>omd update-apache-config [site]</tt> as root user after executing <tt>omd update</tt>.
