Check_MK Werk 5435: Fixed "omd update" problems when updating from 1.4.0p17 or older

by Lars Michelsen

ID: 5435 Title: Fixed "omd update" problems when updating from 1.4.0p17 or older Component: Site Management Level: 2 Class: Bug fix Version: 1.5.0i1 When executing "omd update" as site user to update a site from 1.4.0p17 or older an error could occur blocking the update. The message looks like this: <pre> Traceback (most recent call last): File "/omd/versions/1.4.0p17.cee/bin/omd", line 52, in <module> import tarfile, fnmatch File "/omd/versions/1.4.0p17.cee/lib/python2.7/tarfile.py", line 52, in <module> import copy File "/omd/versions/1.4.0p17.cee/lib/python2.7/copy.py", line 52, in <module> import weakref File "/omd/versions/1.4.0p17.cee/lib/python2.7/weakref.py", line 14, in <module> from _weakref import ( ImportError: cannot import name _remove_dead_weakref </pre> This issue was caused by a mixup of python versions during the update which has been fixed now by using the correct libraries during the update. To workaround this issue, you could run the "omd update" command as root user instead of the site user.

Check_MK Werk 5410: Windows agent: handle section Skype correctly

by Jukka Aro

ID: 5410 Title: Windows agent: handle section Skype correctly Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 Windows agent was giving empty output for section Skype for a number of reasons for all agent versions since 1.4.0: * Windows registry was queried with an illegal parameter REG_MULTI_SZ passed to RegOpenKeyExW. Starting from Windows Server 2016, this illegal parameter caused the query to fail with "access denied". * Werk #4007 fix (commit b89af681c90) caused the entire Skype section to fall out if querying any of the subsection queries to Windows registry failed. Werk #4007 was fixed based on the incorrect assumption that Skype performance counters were queried over WMI. In fact, they query Windows registry PerfLib instead of WMI. * The perf counter name "LS:JoinLauncher - Join Launcher Service Failures" was misspelled in singular, causing also this query to fail. This subsection had never been working correctly. * On master branch, the refactoring done in 6946cb0b8e12b5a41c24a9e02c0f5fd472b214df broke the resolving of counter base numbers based on their names. These causes of failure are now fixed in Windows agent. The spelling of LS:JoinLauncher is also corrected in Skype check code. The performance of Skype perf counter queries got awkward after reverting Werk #4007, that is, executing all of the subsection queries even if some of them failed due to missing perf counters. This is now fixed by mapping the perf counters names to their counter base numbers once and reusing this mapping for all desired perf counters. This avoids the unnecessary looping through Windows registry for each perf counter separately. New log entries are now being made for functionality related to perf counters in order to make debugging easier.

Check_MK Werk 5354: cmctc_lcp: Fixes an error leading to wrong inventory and check output

by Tom Baerwinkel

ID: 5354 Title: cmctc_lcp: Fixes an error leading to wrong inventory and check output Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 This werk fixes an error which caused that the inventory for some sensors was not performed correctly. This resulted in a wrong amount of discovered services and a wrong output (numbers and units) for these services . Therefore, the services of the corresponding hosts have to be rediscovered. Temperature sensors are not affected by this error. One other type of sensor is not affected as well. Which sensor type it is might depend on the used Python version. In tests using Python version 2.7.14 Blower sensors were not affected.

Check_MK Werk 5196: Bumped Livestatus stack size to give regex matching more breathing room.

by Sven Panne

ID: 5196 Title: Bumped Livestatus stack size to give regex matching more breathing room. Component: Livestatus Level: 1 Class: Bug fix Version: 1.5.0i1 The current implementation of regular expression matching can use a non-trivial amount of memory (mainly stack), and our previous memory limit was a bit tight. This has been improved, so regular expression matching should work more reliably. Note that this increases the overall amount of memory allocated for Check_MK, but for normal installations the increase should be negligible.
