Check_MK Werk 0244: New features for WATO page Backup & Restore

by mkde

ID: 0244 Title: New features for WATO page Backup & Restore Component: WATO Level: 2 Class: New Feature Version: 1.2.5i1 H1:Introduction The entire monitoring environment with its configurations, performance data, historic data is a collection of files and folders. So if we want to create a snapshot of the current setup all we have to do is to pack these files into a tarball. This tarball can be applied on the same site (configuration rollback) or applied onto an other monitoring instance. H1:Snapshot backup domains Version <b class=new>1.2.4</b> introduces configurable snapshots. With this new feature you can select the components, also called backup domains, which should get included into the snapshot. Additionally you can provide a comment which is also stored in the snapshot. The following components are currently available <img border=0 src="bilder/extended_backup.png" width=617></a> As you see, some of them are enabled by default. Those default backup domains are included in automatically generated snapshots, which are created when you press the "Activate Changes!" button, for example. H1:Restoring snapshots Most of the time snapshots won't have all configurable backup domains included, but only the default configuration. Therefore we can't apply these snapshots like in previous version: <ul> <li>Remove all possible target files and directories</li> <li>Extract snapshot into the target directories</li> </ul> Now a snapshot is extracted in a more detailed manner: <ul> <li>Look into the snapshot and determine backup domains</li> <li>Remove all target files and directories only from these domains</li> <li>Extract each domain in its target directory</li> </ul> So if we have a snapshot containing only "Automatically detected services", no other directories than the autochecks directory will be emptied upon application. You can find more detailed information about each backup domains files and directories in the following chapter. <b>Important:</b><br> Keep in mind that whenever a backup domain is restored, any of its current data is completely removed.<br> If you restore a snapshot containing "Performance Data" for example, all recent performance data is lost. H1:Configuration details The following four backup domains are the <b>default domains</b>.<br> When you press the "Activate Changes!" button, these domains are automatically included into the snapshot.<br> <ul> <li>Hosts, Services, Groups, Timeperiods, Business Intelligence and Monitoring Configuration</li> This incluces all configuration files generated by WATO and check_mk.<br> Path prefix: <tt>defaults.default_config_dir</tt> <table style='width: 250px'><tr><th width=50>Type</th><th>Relative Path</th></tr> <tr><td>File</td><td>liveproxyd.mk</td></tr> <tr><td>File</td><td>main.mk</td></tr> <tr><td>File</td><td>final.mk</td></tr> <tr><td>File</td><td>local.mk</td></tr> <tr><td>File</td><td>mkeventd.mk</td></tr> <tr><td>Directory</td><td>conf.d</td></tr> <tr><td>Directory</td><td>multisite.d</td></tr> <tr><td>Directory</td><td>mkeventd.d</td></tr> <tr><td>Directory</td><td>mknotifyd.d</td></tr> </table> <br> <li>Personal User Settings and Custom Views</li> The users bookmarks, views, viewoptions, current state of foldable elements and more.<br> Path prefix: <tt>defaults.var_dir</tt> <table style='width: 250px'><tr><th width=50>Type</th><th>Relative Path</th></tr> <tr><td>Directory</td><td>web</td></tr> </table> <br> <li>Local Authentication Data</li> Anything the user needs for the authentication in multisite<br> Path prefix: dirname of <tt>defaults.htpasswd_file</tt> <table style='width: 250px'><tr><th width=50>Type</th><th>Relative Path</th></tr> <tr><td>File</td><td>htpasswd</td></tr> <tr><td>File</td><td>auth.secret</td></tr> <tr><td>File</td><td>auth.serials</td></tr> </table> <br> <li>Event Console Configuration</li> The status of the event console and its configuration.

Check_MK Werk 0314: Fix CMC not executing any Check_MK checks after config reload

by Mathias Kettner

ID: 0314 Title: Fix CMC not executing any Check_MK checks after config reload Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.5i1 CMC uses Check_MK in the <tt>--keepalive</tt> mode. That mode mixed up it's filedescriptors after a configuration reload. That resultet in the output of the checks not arriving at the CMC. The CMC waited and considered the helper as busy. All Check_MK based checks got stale. A restart fixed that. That problem is now solved.

Check_MK Werk 0399: check_ftp: cleanup configuration via WATO, remove Hostname field

by Mathias Kettner

ID: 0399 Title: check_ftp: cleanup configuration via WATO, remove Hostname field Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.5i1 The <tt>check_ftp</tt> active check does not longer need nor allow to specify a host name. The host name is always present: the host the check is mapped onto. Also the specification of an alternative host name would not be consistent with any of the other networking checks. If you need an FTP check on a specific host then please add that host to the monitoring. Exceptions can alsway be done via <tt>custom_checks</tt>.

by Lars Michelsen

ID: 0390 Title: Added an icon selector to the view editor Component: Multisite Level: 2 Class: New Feature Version: 1.2.5i1 Each view can have a small icon which is used, for example, in context buttons linking to these views.
