Check_MK Werk 5267: cmk-update-agent: New binary format of Agent Updater executable on Linux

by Andreas Umbreit

ID: 5267 Title: cmk-update-agent: New binary format of Agent Updater executable on Linux Component: agents Level: 2 Class: New feature Version: 1.5.0i2 The cmk-update-agent executable is now implemented as a packaged binary executable. This werk consists of many changes that have partly already been applied to Check_MK 1.5.0i1. The new format addresses several problems and yields some improvements: * Better compatibility: All requirements regarding the installed Python Interpreter or other packages/programs were eliminated; the only requirements left are a x86_64 processor architecture and a glibc 2.5 or above. * More convenient communication to Check_MK Server: All GET-Requests have been replaced with according POST-Requests. This improves security as sensitive data is no longer sent within the URL of the HTTP(S) request. * Only one copy of cmk-update-agent: The copy of cmk-update-agent previously placed under /usr/bin/cmk-update-agent has been replaced by a shell script that executes the actual cmk-update-agent executable situated at the Check_MK Agent plugin directory. This eliminates the need to maintain two places when manually replacing cmk-update-agent for debugging reasons. However, it is still possible to execute a copy of the cmk-update-agent executable directly. * Notably, there will be no more problems with curl and because all communication is now done via python-requests, which is included within the cmk-update-agent executable as mentioned above.

Check_MK Werk 5415: Make Windows section openhardwaremonitor backwards compatible

by Jukka Aro

ID: 5415 Title: Make Windows section openhardwaremonitor backwards compatible Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i2 Version 1.4.0 'corrected' the naming of section openhardwaremonitor. Unfortunately, this broke the backwards compatibility of old ini files that still call this 'ohm'. The fix maps the old name to the new one so that both old and new ini files work. Moreover, the agent bakery was still writing ini files with the old name. Now the agent bakery is also fixed.

Additionally, an MSI-Installation log will be written on update if there is a log-dir available.

Check_MK Werk 5265: cmk-update-agent: Enable Agent Updater to update itself on Windows

by Andreas Umbreit

ID: 5265 Title: cmk-update-agent: Enable Agent Updater to update itself on Windows Component: agents Level: 2 Class: Bug fix Version: 1.5.0i2 When triggering an update under Windows, the agent updater could not be replaced by its new downloaded version because it was still running from the corresponding file. This situation is now mitigated by restarting the agent updater from within ../temp when running from plugins-dir. This is relevant only for a manual execution of cmk-update-agent.exe

Check_MK Werk 5254: Event console: Introduced syslog application placeholder which can be used in rewriting events

by Andreas Boesl

ID: 5254 Title: Event console: Introduced syslog application placeholder which can be used in rewriting events Component: Event Console Level: 1 Class: New feature Version: 1.5.0i2 When rewriting text, hostname or application for an event you can now use the new placeholders Message text regex match groups <ul> <li>$MATCH_GROUPS_MESSAGE_1$</li> <li>$MATCH_GROUPS_MESSAGE_2$</li> <li>$MATCH_GROUPS_MESSAGE_n$</li> </ul> Syslog application regex match groups <ul> <li>$MATCH_GROUPS_SYSLOG_APPLICATION_1$</li> <li>$MATCH_GROUPS_SYSLOG_APPLICATION_2$</li> <li>$MATCH_GROUPS_SYSLOG_APPLICATION_n$</li> </ul> Note: The syslog application match groups are now also considered when canceling events. The previous version did only check for identical create/canceling match groups in the event message text.

Check_MK Werk 5253: Linux check_mk_agent: now able to execute plugins for real time checks

by Andreas Boesl

ID: 5253 Title: Linux check_mk_agent: now able to execute plugins for real time checks Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i2 The file <tt>/etc/check_mk/real_time_checks.cfg</tt> now supports the parameter <tt>RTC_PLUGINS</tt> which allows the configuration of plugins to be also executed as real time checks. For example F: RTC_PLUGINS+="apache_status" RTC_PLUGINS+="lvm" This executes both plugins as real time checks (1sec resolution) as well as standard check_mk check.

Check_MK Werk 5483: mknotifyd: improve error handling and logging

by Tom Baerwinkel

ID: 5483 Title: mknotifyd: improve error handling and logging Component: Notifications Level: 1 Class: Bug fix Version: 1.5.0i2 Connections in progress are now explicitely written to the mknotifyd.log. This makes it easier to spot ongoning, unsucessful connection attempts. Furthermore, in case of polling errors a timeout of 1s was added. This prevents the mknotifyd from using 100% CPU if an error appears and the polling returns immediately.
