[2.3.0] Checkmk Werk 16607 created: Handle the uptime of Docker containers across time zones

by Checkmk werks level 1

[//]: # (werk v2) # Handle the uptime of Docker containers across time zones key | value ---------- | --- date | 2024-04-12T09:35:03+00:00 version | 2.3.0b6 class | fix edition | cre component | checks level | 1 compatible | yes As of version 2.3, the uptime monitoring service for Docker containers could crash if the container's start time was later than the current CheckMk site's current time. This resulted in a negative uptime calculation error (ValueError: "Cannot render negative timespan"). This could occur in situations where the host system and the container had different configured timezones. We now correctly handle all timestamps, ensuring accurate uptime calculations regardless of timezone configurations.

[2.3.0] Checkmk Werk 16799 created: Custom & forecast graphs: More descriptive error messages in case of missing user input when configuring metrics

by Checkmk werks level 1

[//]: # (werk v2) # Custom & forecast graphs: More descriptive error messages in case of missing user input when configuring metrics key | value ---------- | --- date | 2024-04-19T10:57:49+00:00 version | 2.3.0b6 class | fix edition | cee component | metrics level | 1 compatible | yes When configuring the metrics rendered in custom and forecast graphs, users have to select a host, a service and a metric. Previously, if any of these fields were missing, the Checkmk UI displayed the message "Cannot calculate graph recipes" and an uninformative traceback. As of this werk, the UI instead displays a descriptive error message.

[2.3.0] Checkmk Werk 16689 created: Decommission legacy check API

by Checkmk werks level 1

[//]: # (werk v2) # Decommission legacy check API key | value ---------- | --- date | 2024-04-17T06:27:51+00:00 version | 2.3.0b6 class | feature edition | cre component | checks level | 1 compatible | no This werk only affects users and maintainers of custom check plugins developed against the API that was replaced in Checkmk 2.0.0. The old API for the plugins residing in `local/share/check_mk/checks` will no longer be stable in Checkmk version 2.3. Plugins not maintained by Checkmk will almost certainly be incompatible and therefore ignored. Compatible plugins _will_ be considered, but the notion of what constitutes a compatible plugin may change any time. As of Checkmk version 2.2 plugins in that folder generated a warning on the commandline and resulted in an <i>"Analyze Configuration"</i> test issueing a WARNING. We now escalate this to CRITICAL. Incompatible plugins are reported during `omd update`. If you maintian such plugins, please migrate them to the new API before upgrading to Checkmk 2.3. You can find a blog post on how to migrate these plugins [here](https://checkmk.com/blog/migrating-check-plug-ins-to-checkmk-2-0). A comprehensive guide on how to write plugins is found [in our documentation](https://docs.checkmk.com/2.3.0-beta/en/devel_check_plugins.h…. Please also refer to the APIs documentation found in your site (Help -> Check plugin API reference). Commandline call plugins for special agents and active checks in this folder will still work, but we provide a new API for those as well now (see [Werk #16259](https://checkmk.com/werk/16259)). They will stop working in Checkmk 2.4.

[2.3.0] Checkmk Werk 16357 created: Check certificates: Fix checking of common name of issuer

by Checkmk werks level 1

[//]: # (werk v2) # Check certificates: Fix checking of common name of issuer key | value ---------- | --- date | 2024-04-18T11:02:41+00:00 version | 2.3.0b6 class | fix edition | cre component | checks level | 1 compatible | yes The active certificate check (configured via the ruleset *Check certificates*) did not check the common name (CN) of the certificate issuer correctly: * If only the checking of the issuer CN was activated, the CN of the subject was checked instead. * If both the checking of the issuer and the subject CN where activated, the active check crashed with\ <code>error: the argument '--subject-cn \<SUBJECT_CN\>' cannot be used multiple times.</code>
