Checkmk Werk 12830: Cleanup abandoned user profile directories after 30 days

by Lars Michelsen

ID: 12830 Title: Cleanup abandoned user profile directories after 30 days Component: Multisite Level: 1 Class: New feature Version: 2.1.0i1 Each user that is able to log into the Checkmk GUI gets a user profile directory created below <tt>var/check_mk/web/[user_id]</tt>. During deletion of a user, the profile directory is not deleted automatically. This is done to prevent loss of user configurations when users are deleted accidentally and recreated later. While this is helpful for the case mentioned above, this may result in abandoned user profile directories. Especially in the case where a large number of users was created (e.g. by an LDAP synchronization) and later removed, this could lead to a large number of directories. With a large number of directories, this may even affect the performance of different parts of the GUI. The now introduced housekeeping logic will detect all directories not belonging to an existing user. For each of these directories it will find the most recent modified file. In case this file modification is older than 30 days, the profile directory will be deleted.

Checkmk Werk 12491: No autorefresh in Custom Graph editor

by Óscar Nájera

ID: 12491 Title: No autorefresh in Custom Graph editor Component: metrics Level: 1 Class: New feature Version: 2.1.0i1 The custom graph editor in a pursuit of convenience would save changes and refresh the page on every change. This convenience resulted in a high performance penalty when editing graphs with multiple metrics, as the entire page would need to be rendered again, and specially recollecting data from the RRD files. With this Werk, the custom graph editor does not execute the page reload upon changes. The user is now responsible for this interaction. Following our UX project, now there is an "Apply" button on the top left corner of the editor to save and apply the changes to the graph. This allows users to place multiple changes at once, without incurring in a performance penalty, due to the constant refreshing of the editor. Users do need to press the "Apply" button to save changes, it is now not enough to just do changes and leave the editor.

by Moritz Kiemer

by Andreas Boesl

ID: 12468 Title: BI aggregations no longer show duplicate subtrees and nodes Component: BI Level: 1 Class: Bug fix Version: 2.1.0i1 Some search operations for BI nodes lead to similar (but not equal) results. However, the generated aggregation nodes from these results could be identical. A new deduplication mechanism fixes this bug.

Checkmk Werk 12810: check_mk_agent.solaris: fix error "integer expression expected"

by Ulrich Bschorer

ID: 12810 Title: check_mk_agent.solaris: fix error "integer expression expected" Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The check_mk_agent for solaris reported the error "integer expression expected" while executing the "<<<job>>>" section. The cause of this error is that solaris does not support "su -s". This bugfix removes the parameter "-s" from the su command. Therefore statistics for jobs of users that have no login shell (e.g. www-data) are not supported for solaris systems. In order to apply this bugfix you have to redeploy the agent.

by External contributor

ID: 12877 Title: <tt>printer_supply</tt>: handle trailing null bytes in prtMarkerColorantValue Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The check plugin <tt>printer_supply</tt>, which monitors the fill levels of printer supplies via SNMP, is now able to handle trailing null bytes in the field prtMarkerColorantValue (observed for example for HP Jetdirect 153).
