Checkmk Werk 13739: jenkins_nodes: Allow negative timespan for Clock difference

by Lukas Lengler

ID: 13739 Title: jenkins_nodes: Allow negative timespan for Clock difference Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The Clock difference of a Jenkins node can be negative if the node's time is running ahead. In this case the check would crash because negative values cannot be rendered as a timespan. Now the absolute value of the time is used and displayed.

Checkmk Werk 13812: KUBE kube_cpu use latest cpu usage value when no new data is available

by Wontek Hong

ID: 13812 Title: KUBE kube_cpu use latest cpu usage value when no new data is available Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The check returned a 0 cpu usage value when the Kubernetes special agent was polled too frequently. This werk fixes this behaviour and returns the last reported usage value for a time interval of 60 seconds if no new data is available from the agent. If the last reported value is older than 60 seconds than the usage value will be omitted.

Checkmk Werk 13094: Various ValueSpec-related API cleanups

by Sven Panne

ID: 13094 Title: Various ValueSpec-related API cleanups Component: Checks & agents Level: 2 Class: New feature Version: 2.2.0i1 Various changes have been done to <tt>ValueSpec</tt> and its subclasses, improving maintainability and robustness. If you don't write your own complicated <tt>ValueSpec</tt> subclasses and you don't have any self-written complicated check parameters, you are probably not affected. <ul> <li> <tt>ValueSpec</tt>'s constructor doesn't accept any random unspecifed keyword arguments anymore. It is better to raise an exception at the incorrect call site than silently accepting every typo. To fix any problems with this change, just remove the offending keyword arguments, they served no purpose after all. </li> <li> <tt>ValueSpec.canonical_value()</tt> is an abstract method now, otherwise we force lots of places to handle <tt>None</tt>. Previously quite a few things worked only more or less by accident. If you implement your own <tt>ValueSpec</tt> subclass, you have to implement that method now, unless an intermediate class already does it for you. </li> <li> <tt>DropdownChoice</tt> and <tt>CascadingDropdown</tt> don't have a <tt>no_preselect</tt> keyword argument anymore. It was redundant, because <tt>no_preselect_title</tt> is enough: If this keyword argument is not <tt>None</tt>, <tt>no_preselect=True</tt> is implied. Previously one could specify nonsensical combinations of those arguments. To fix any problems with this change, just drop the <tt>no_preselect</tt> keyword argument. </li> <li> <tt>Alternative</tt>, <tt>UploadOrPasteTextFile</tt>, <tt>TextOrRegExp</tt>, and <tt>CAorCAChain</tt> don't have a <tt>style</tt> keyword argument anymore. It didn't serve any purpose since Checkmk 2.0. Just remove it. </li> </ul>

Checkmk Werk 13639: Fix displaying agent output on crash report page

by Lars Michelsen

ID: 13639 Title: Fix displaying agent output on crash report page Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 When the crash report page displayed a agent based check report, it displayed an error message "Internal error: Unsupported type <class 'bytes'>" in the "Agent output" box. The agent output can now be displayed again, even if it might not be 100% correct in case there are characters included in the agent output which can not be encoded in the default page encoding (UTF-8). This is OK, because the agent output there is only for informational purposes. Users that want to have the full and correct agent output can download the crash report archive and extract the agent_output file from it.

Checkmk Werk 13084: Reintroduce housekeeping job before activation runs

by Christoph Rauch

ID: 13084 Title: Reintroduce housekeeping job before activation runs Component: Core & setup Level: 1 Class: Bug fix Version: 2.2.0i1 In previous versions, the activation housekeeping job was changed to a background-job running every minute because the run sometimes took longer than 2 minutes (a hard timeout). Due to race conditions this change led to errors (missing activations) in some cases. Only having it delete activations older than 1h however led to exhaustion of disk-space in some cases. This change reintroduces the previously dropped house-keeping run right before the activation is started, while keeping the periodically run house-keeping job to clean up afterwards.
