Checkmk Werk 12026: Performance Graph Dashlets: Specify by Graph Title instead of by Index

by Joerg Herbel

ID: 12026 Title: Performance Graph Dashlets: Specify by Graph Title instead of by Index Component: Setup Level: 1 Class: New feature Version: 2.1.0i1 The graph displayed by a performance graph dashlet is now specified by selecting from a list of available graphs, represented by their titles. This list can optionally be pre-filtered by host name or service description. Before this werk, graphs in performance graph dashlets were specified by a number indexing the graphs produced by the corresponding service (n'th graph). Performance graph dashlets created before this werk will continue to work. However, upon editing them the next time, you will have to re- select the graph to be displayed.

Checkmk Werk 12135: More detailed audit logging

by Lars Michelsen

ID: 12135 Title: More detailed audit logging Component: Setup Level: 2 Class: New feature Version: 2.1.0i1 With Checkmk 2.0 the audit logging of the setup has been extended to be more detailed. We added the general capability of tracking changes to configuration objects on attribute level. The audit log can be opened going to "Setup > General > Audit log". On that page you have the list of recorded changes with the new "Details" column. You also have the general filter form that can be used for filtering the changes you are interested in. You can also find context related links from hosts, users and rules to the audit log entries that are specific to this object. You may notice that the "Details" column is empty for a lot of changes. This is because we need to turn on the recording of details specific to each action. In Checkmk, we have implemented this for the most common actions first. These are: <ul> <li>Create, edit and delete hosts</li> <li>Create, edit and delete folders</li> <li>Service discovery (bulk and single host discovery)</li> <li>Create, edit and delete users</li> <li>Create, edit, move and delete rules</li> </ul> Over time, we will increase the level of detail of the other existing log messages.

Checkmk Werk 11975: Validate regexes in BI rules during config update

by Ulrich Bschorer

ID: 11975 Title: Validate regexes in BI rules during config update Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0i1 Unfortunately Python 2 allowed to enter invalid regexes into arguments of BI rules. In Python 3 these values will lead to a crash when evaluating the service condition. E.g. a argument like "C:\Users\" leads to the error message "re.error: incomplete escape \U at position 2". Therefore the Checkmk update procedure (cmk-update-config) validates the regular expressions in BI rules and logs "ERROR: Invalid regular expression in BI rule detected" if the regex cannot be evaluated. If you encounter these errors your configuration probably contains rules that needs to be corrected. Previous Checkmk versions were not complaining about those rules but they were not able to match. You should change these rules according to https://docs.checkmk.com/latest/en/regexes.html prior to the update of your production site. E.g. you should change windows paths like "C:\Users\" to "C:\\Users\\" with double backslashes.

Checkmk Werk 12134: Fix dynamic configuration executing only phase 1 in some cases

by Lars Michelsen

ID: 12134 Title: Fix dynamic configuration executing only phase 1 in some cases Component: Dynamic host configuration Level: 1 Class: Bug fix Version: 2.1.0i1 When a dcd connection was configured to operate in the central site of a distributed setup, the connection could fail with only executing the phase 1 of the synchronization. This was caused by a file <tt>etc/check_mk/dcd.d/wato/distributed.mk</tt> in the central site telling the DCD that it was a remote site.
