Check_MK Werk 2656: windows agent can now optionally output the full command line in the ps section

by Sebastian Herbord

ID: 2656 Title: windows agent can now optionally output the full command line in the ps section Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i3 This feature requires wmi which is also a configuration switch. As a side-effect, the windows agent now includes a native c++ wmi wrapper which may be useful in the future.

Check_MK Werk 2655: Windows Agent can now read additional settings from an optional check_mk_local.ini file

by Sebastian Herbord

ID: 2655 Title: Windows Agent can now read additional settings from an optional check_mk_local.ini file Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i3 The settings from check_mk_local.ini (if it exists) will be merged with the settings from check_mk.ini in a reasonable way. What is reasonable depends a lot on the parameter. Settings that have only one value (i.e. port) will simply be overwritten by the "local" settings. Many settings that can appear repeatedly, i.e. performance counters, will be appended. Yet other settings, especially those with pattern where only the first match applies, the "local" settings will be prepended to the existing settings (thus have higher priority). If in doubt about how the files are being combined, you can run "check_mk_agent.exe showconfig" to display the effective settings after merging the two files.

Check_MK Werk 2649: Bulk renaming of hosts in WATO

by Mathias Kettner

ID: 2649 Title: Bulk renaming of hosts in WATO Component: WATO Level: 2 Class: New Feature Version: 1.2.7i3 The function for renaming hosts in WATO is now available in a new bulk mode. This is a new button in each folder, where you can recursively rename hosts in a generic way. There are several types of renamings that can be done: LI:case translation into lower or upper case LI:adding and removing suffixes LI:adding prefixes LI:regular expression operations (much like <tt>sed</tt>) LI:explicit mappings For each affected site only <b>one</b> restart of the site is needed. This can speed up renaming operations with lots of hosts drastically when compared to renaming each host apart.

Check_MK Werk 2654: logwatch: fixed high memory and cpu usage caused by too many unacknowledged messages

by Sebastian Herbord

ID: 2654 Title: logwatch: fixed high memory and cpu usage caused by too many unacknowledged messages Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.2.7i3 Due to a change in werk 2414, the local copy of the monitored logfile continued to grow and was parsed in every check cycle. With growing file size this could cause extreme cpu and memory load. This fix is twofold: a) The check now stops appending to the file once the filesize limit is reached. This was the behaviour pre-2414 anyway b) The configurable reclassification patterns are now only applied to old loglines once after each change to the patterns. Please note that this doesn't automatically truncate the copy of the logfile if it already exceeds the size limit.

Check_MK Werk 2647: Fix crash of CMC in case of duplicate host

by Mathias Kettner

ID: 2647 Title: Fix crash of CMC in case of duplicate host Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.7i3 In certain situtations when you have a non-valid configuration (e.g. a duplicate host) than the Check_MK Micro Core would not be able to start correctly due to a problem in the handling of errors in the RRD creation helper. This has been fixed.

Check_MK Werk 2433: interface checks: now able to configure the infotext shown in the check output

by Andreas Boesl

ID: 2433 Title: interface checks: now able to configure the infotext shown in the check output Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i3 You can now configure with the WATO rule <i>Network interfaces and switch ports</i> the infotext between the [] brackets. The following options are available. <ul> <li>Show alias</li> <li>Show description</li> <li>Show alias and description</li> <li>Show alias if set, else description</li> <li>Show description if set, else alias</li> <li>Hide infotext</li> </ul>

Check_MK Werk 2646: New system for displaying time graphs of metrics

by Mathias Kettner

ID: 2646 Title: New system for displaying time graphs of metrics Component: Multisite Level: 3 Class: New Feature Version: 1.2.7i3 Check_MK now has a new implementation of how metrics time graphs (formerly known as performance graphs or PNP graphs) are being created. Instead of hand crafted PNP templates, templates are now being created by Check_MK's new metrics system. In the new declaration file <tt>share/check_mk/web/plugins/metrics/check_mk.py</tt> all names of performance variables are being assigned to units, titles and colors. Graph and Perf-O-Meter definitions both make use of these. The advantages are: LI:Graphs and Perf-O-Meters are much simpler to declare LI:Graphs and Perf-O-Meters now share the same color scheme LI:Graphs are more streamlined LI:It is now much easier to change some general properties of all graphs LI:Default graphs are more intelligent LI:Future addons that work with metrics data are easier to implement Note: existing PNP templates have not been removed but still exist and have precedence over the automatically generated ones. But they will not be maintained anymore and no new manual templates will be created by us anymore.
