Module: check_mk Branch: master Commit: bed81e57c162d8420b3cf3df8badc0fa0c3de0b7 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=bed81e57c162d8… Author: Simon Betz <si(a)mathias-kettner.de> Date: Tue Jan 16 13:21:25 2018 +0100 5618 FIX skype.sip_stack: Fixed "missing key" error which caused a check crash Above error was a result of different key notations for the same object, eg. in "skype.sip_stack" we got - "SIP - Incoming Responses Dropped /Sec" and - "SIP - Incoming Responses Dropped/sec" Now we normalize these keys by ignoring upper/lower case and spaces.
