Checkmk Werk 14084: Deprecate old HW/SW inventory plugin API

by Moritz Kiemer

ID: 14084 Title: Deprecate old HW/SW inventory plugin API Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 This werk only affects users and maintainers of custom hardware/software inventory plugins. The old API for the plugins residing in <tt>{local/,}share/check_mk/inventory</tt> will be removed in Checkmk version 2.2. Plugins in that folder will be ignored starting with 2.2. However, they keep working with the 2.1 for the transition period. As of Checkmk version 2.1 plugins in that folder will generate a warning on the commandline and result in an <i>"Analyze Configuration"</i> test going to {{WARN}}. If you maintian such plugins, please migrate them to the new API before upgrading to Checkmk 2.2. New plugins live in <tt>lib/check_mk/base/plugins/agent_based/</tt>. You can find an example for a migration on github <a href="https://github.com/tribe29/checkmk/commit/0264b6acdef677ff7ae323a696ddbe17d…">here</a> and <a href="https://github.com/tribe29/checkmk/commit/e926cc58adb8297030fb03d61c7854a96…">here</a>. Also refer to the APIs documentation found in your site (Help -> Check plugin API reference).

Checkmk Werk 13857: Windows agent uses perflib to obtain wmi_cpuload data

by Sergey Kipnis

ID: 13857 Title: Windows agent uses perflib to obtain wmi_cpuload data Component: Checks & agents Level: 2 Class: New feature Version: 2.2.0i1 Windows agent uses now the Perflib API for service wmi_cpuload as a more reliable and stable source of information compared to the previously used WMI API. If, for some reasons, the new functionality causes problems, it is possible to return to the WMI API, using the appropriate key in the user config. To do it, set in section global the key cpuload_method to 'use_wmi'.

Checkmk Werk 13748: Support Diagnostics: Missing performance report

by Lars Getwan

ID: 13748 Title: Support Diagnostics: Missing performance report Component: Setup Level: 1 Class: Bug fix Version: 2.2.0i1 In an environment with multiple sites on one server or with multiple CMK servers added as hosts, the performance report was sometimes missing in the Support Diagnostics dump. The reason was: When creating a Support Diagnostics dump, the hostname of the Checkmk server is determined using a Livestatus query. The query previously used, returned multiple servers in some cases, and the first one listed was used. This fix uses a new query that is more reliable.

Checkmk Werk 13899: Notification spooler: Support for TLS authentication

by Maximilian Wirtz

ID: 13899 Title: Notification spooler: Support for TLS authentication Component: Notifications Level: 1 Class: Security fix Version: 2.2.0i1 Previously mknotifyd did not authenticate peers. With this Werk mknotifyd can be configured to require TLS client certificate authentication. This is only available if encryption for mknotifyd is configured. In order to verify the peers correctly the corresponding site CAs must be trusted. This is usually the case if you enabled the configuration sync and enabled the encryption of livestatus. If you have another setup make sure both all Site CAs are trusted on each site.

Checkmk Werk 14104: Fix error on adding views to reports

by Ronny Bruska

ID: 14104 Title: Fix error on adding views to reports Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 If you used report options in the "Add to" menu of views, an error like "Cannot load reports from /omd/sites/beta/var/check_mk/web/USER/user_reports.mk: invalid syntax (<unknown>, line 1)" occured. If you still see this error while opening views or reports, you have to edit the file /omd/sites/beta/var/check_mk/web/USER/user_reports.mk and change all occurrences of entries like {'title': l'MY_TITLE'} to {"title: 'MY_TITLE'}. Another option is to simply delete the file, but your saved options will be lost.

Checkmk Werk 14121: KUBE: Import annotations as host labels

by Solomon Jacobs

ID: 14121 Title: KUBE: Import annotations as host labels Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 By default, Checkmk does not import Kubernetes annotations. With this werk, this bevaviour can be configured via the option <tt>Import annotations as host labels<\tt> in the rule <tt>Kubernetes<\tt>. The option allows importing any Kubernetes annotation that is a valid Kubernetes label. These imported annotations are added as host labels to their respective piggyback host using the syntax <tt>cmk/kubernetes/annotation/{key}:{value}<\tt>. You can further restrict the imported annotations by specifying a pattern which Checkmk searches for in the key of the annotation.
