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 13623: New default dashboards for linux and windows

by Marcel Arentz

ID: 13623 Title: New default dashboards for linux and windows Component: Multisite Level: 2 Class: New feature Version: 2.1.0i1 With this werk 4 new default dashboards are added to Checkmk. These are: * Linux hosts: A default dashboard to be used for a (smaller) group of Linux hosts, e.g. a cluster. You will find this dashboard in the "Overview" topic of the Monitor menu. * Windows hosts: A default dashboard like the above but for windows hosts. * Single Linux host: A host specific dashboard for Linux hosts. This dashboard is available through the context of a Linux host or though the link of the particular host in the overview dashboard. * Single Windows host: A host specific dashboard like the above but for windows hosts. You will find the group dashboards on Monitor > Overview and below the entry "All hosts". Both dashboards are prefilterted to hosts with the according operating system. But the scope is a smaller group of related host, e.g. a cluster of linux or windows server. Because of that it is recommended, to add more filters to get an actual overview of a specifc group of linux/windows hosts. The single host dashboards linked in the host name column, reachable through the "Host information" dashlet of the group dashboard. Alternatively you can reach them through the host overview itself by the "Host" dropdown at the topic "Overview".

Checkmk Werk 13083: cleanup only very old activations

by Christoph Rauch

ID: 13083 Title: cleanup only very old activations Component: Core & setup Level: 2 Class: Bug fix Version: 2.1.0i1 During the process of "activating changes" it was possible in certain situations that the activation-ID would disappear before the activation could have a chance to complete. Investigations showed that a cleanup job removed these activations before they even started. This could then manifest itself as the error: "Missing Activation ID" or a response with a 404 status in the REST API. This werk fixes this problem by changing the cleanup job to only consider activations which are at least an hour (3600 seconds) old. There are no further changes needed for this to take effect.

Checkmk Werk 13288: Improve speed of activate changes by incremental activating changes

by Andreas Boesl

ID: 13288 Title: Improve speed of activate changes by incremental activating changes Component: Setup Level: 2 Class: New feature Version: 2.1.0i1 With this change the microcore and its helper processes are able to reuse parts of the previous configuration, without compiling everything anew. Only actually changed hosts will be fully recompiled. This can significantly reduce the waiting time for "Activate changes". In addition, the workload during the compilation phase is also reduced, giving the monitoring core some room to breathe. F+: ## Compilation time comparison using a demo config with 150k services ## # Full compiliation of all hosts (default behaviour in all previous versions) real 0m21.107s user 2m10.626s sys 0m2.581s # Using new incremental activation real 0m6.936s user 0m24.366s sys 0m1.492s F-: The incremental activation mechanism is used automatically when it is feasible. Actions where hosts are changed (edit/add/remove/discovery) can make use of this new feature. However, changes to rulesets require a complete recompilation of the entire configuration, just as in previous versions.

Checkmk Werk 13574: Update net-snmp lib to 5.9.1

by Timotheus Bachinger

ID: 13574 Title: Update net-snmp lib to 5.9.1 Component: inline-snmp Level: 2 Class: Bug fix Version: 2.1.0i1 We now ship omd with the net-snmp lib in version 5.9.1. This was motivated by several reasons: * The previously used net-snmp lib had a bug in the python C binding which caused any higher auth protocol then SHA/MD5 not working. (e.g. SHA256, SHA512 etc.). This affected the inline SNMP mode in checkmk only. * The net-snmp project had a long time no releases. So we now want to go for the latest release.
