Checkmk Werk 10601: Auto migration of check plugins to new section definitions

by Moritz Kiemer

ID: 10601 Title: Auto migration of check plugins to new section definitions Component: Checks & agents Level: 2 Class: New feature Version: 1.7.0i1 We are now converting all plugins to the new format expected by the future API. Migrated are plugins from <ul> <li>share/check_mk/checks</li> <li>local/share/check_mk/checks</li> <li>share/check_mk/inventory</li> <li>local/share/check_mk/inventory</li> </ul> Although we are trying to migrate as many check and inventory plugins as possible on the fly, for some plugins this may fail. These are the anticipated reasons why auto-migration may fail: <h4>A cluster aware checkplugin</h4> Checkmk refuses to auto-migrate cluster aware (those with node_info set to True) check plugins. Auto converting the data layout is too error prone. These plugins must be migrated manually. <h4>Checkplugins using 'extra_sections'</h4> Checkmk refuses to auto-migrate check plugins that make use of the 'extra_sections' feature. In the new API the destiction between the regular section and additional 'extra_sections' is not made, and all section content will be passed in its 'parsed' version. Therefore these Plugins have to be migrated manually. <h4>A missing SNMP scan function</h4> Every Checkplugin that specifies an 'snmp_info' key must specify 'snmp_scan_function' as well. <h4>A complex SNMP scan function</h4> If Checkmk fails to auto-migrate a legacy SNMP plugin to a section definition, this is most likely due to an elaborate scan function. For the auto-migration to work, the scan function must be fairly simple. Make sure your scan function has the following properties: <ul> <li>it only consists of one single return statement</li> <li>it does not in turn call other functions (not even 'all' or 'any')</li> <li>it does not negate compound expressions</li> </ul> If in doubt, take a look at scan functions that succeed to be migrated to see what options are available. <h4> Known limitations</h4> <ul> <li>HostLabels that are generated in a subchecks discovery function are lost</li> </ul>

Checkmk Werk 10873: Report headers: Improve handling of titles with dynamic lengths

by Lars Michelsen

ID: 10873 Title: Report headers: Improve handling of titles with dynamic lengths Component: Reporting & Availability Level: 2 Class: Bug fix Version: 1.7.0i1 In previous versions of Checkmk the title of reports could only be set to a fixed size. Especially with generic reports, like host or service reports, this is a problem because the titles can be of different lengths and can even exceed the width of the document. The "One line of text" report element has now a new configuration option "Shrink too long texts", which is disabled by default. Once you enable this option, the text size will be estimated before adding it to the document. In the moment the text is too long, the system tries to wrap the text and reduce the font size at the same time. In many cases the text is inserted in such a way that it fits. There are still cases where the text still cannot be made to fit properly, but for the most common cases this should be a good enough fit. We have changed the default "host" report template to use the new setting for the title of the page. In case your reports are based on your own template and want to use the new option, you will have to enable the option in the report elements of your report template.
