Check_MK Werk 8304: New graphical frontend for metrics time graphs

by Lars Michelsen

ID: 8304 Title: New graphical frontend for metrics time graphs Component: metrics Level: 3 Class: New feature Version: 1.2.7i3 The Check_MK Enterprise Edition has now a new graphical user frontend for displaying metrics time graphs. Instead of using pixeled PNG images it makes use of interactive vector graphics using HTML 5. These graphs do not only look better. They allow you to: LI:Zoom horitontally using your mouse wheel LI:Zoom vertically by dragging points up and down LI:Scroll horizontally (into past and future) by dragging points left and right LI:Resize a graph using the right bottom corner If more than one graph is being displayed on the same HTML page then any zoom or shift in time will be synchronzed to <b>all</b> graphs on the same page. Also the reporting uses the new graphing engine and replaces the embedded pixel images by real vector graphics. A further advantage of the new system is, that in distributed setups no reverse HTTP proxy is needed any longer. The data is being fetched via Livestatus (up-to-date core is neccessary).

Check_MK Werk 8302: New page for downloading the baked monitoring agent of a host

by Lars Michelsen

ID: 8302 Title: New page for downloading the baked monitoring agent of a host Component: agents Level: 2 Class: New feature Version: 1.2.7i3 There is now a new page for every host where you can download it's Check_MK agent. This page has one link for every supported operating system (as WATO cannot know which agent package type you need). Note: The download of baked monitoring agents is only possible for users with the Adminitrator role per default. This is because agent may contain confidential data such as passwords. But if you like you can allow normal users either downloading agents for hosts where they are a contact for or even for all agents.

Check_MK Werk 8303: Added new utility logdate, directly callable without path

by Lars Michelsen

ID: 8303 Title: Added new utility logdate, directly callable without path Component: setup Level: 1 Class: New feature Version: 1.2.7i3 C+: OM:logdate --help Usage: logdate [-h|--help] [FILE1 FILE2 ...] Reads log lines from stdin or from specified files and searches for timestamps in the form [1443685694] (Unix epoch timestamp). Writes the lines to standard output while replacing the timestamps by local times in the format [2015-10-01 09:48:14]. Example: logdate var/check_mk/core/history C-:

Check_MK Werk 8301: cmcdump: New tool for offline mirroring satellite sites into a central site

by Lars Michelsen

ID: 8301 Title: cmcdump: New tool for offline mirroring satellite sites into a central site Component: cmc Level: 3 Class: New feature Version: 1.2.7i3 The CMC now has a new replication mechanism for mirroring the state of satellite monitoring sites into a central site. This is much like <tt>livedump</tt> for the Nagios core but is much more powerful. In order to setup this you need to call <tt>cmcdump -C > cmc.config</tt> on the remote site and transfer that file to the central site into <tt>etc/check_mk/conf.d/yourfile.mk</tt>. This will dump the configuration of all hosts and services. Afterwards activate the updated configuration with <tt>cmk -O</tt>. You need to repeat it from time to time so that your central site is up-to-date. In a much shorter interval (e.g. once per minute) you call <tt>cmcdump > cmc.state</tt> on the same remote site. This can easily be done with a cron job. That file you also transfer to the central site via any mechanism you like (scp, http, rsync, ...). Over there read it into the core with: C+: OM:unixcat < cmc.state tmp/run/live C-: This will update the core's complete state of all hosts and services that are contained in the dump. The transferred state will correctly reflect the following variables: LI:The actual state (PEND, OK, WARN, ...) LI:The plugin output LI:The long (multiline) plugin output LI:The performance data LI:Whether the object is flapping and the current level of flappiness LI:The time of the last check execution LI:The time of the last state change LI:The check execution time LI:The check latency LI:The number of the current check attempt LI:Whether the current state is hard or soft LI:Whether a problem has been acknowledged LI:Whether the object is currently in a scheduled downtime In the central site this will almost - but not entirely - be handled like a check execution. One difference is that no notifications will be sent. But performance data is being processed graphs will be created. Also the monitoring log is being updated and availability data can be processed. Depending on our synchronization interval of the data transfer the latter one might not be 100% precise however. The tool <tt>cmcdump</tt> is in your path and can directly be executed. Call <tt>cmcdump --help</tt> for details on how to call this tool.

Check_MK Werk 8297: Fixed problem where objects stayed in downtime even if downtimes where removed

by Lars Michelsen

ID: 8297 Title: Fixed problem where objects stayed in downtime even if downtimes where removed Component: cmc Level: 2 Class: Bug fix Version: 1.2.7i3 Due to a bug while saving the state of current downtimes it could happen that removing a downtime would not reset the host/service in the state "not in downtime". The blue moon icon stayed at the host - even if there was no downtime left. This has been fixed. The fix can only fix new downtimes automaticall, however. If you still have sticky blue moons then please set and remove downtimes for those. The moon will then vanish.
