Check_MK Werk 8067: Delay service notification when host comes up

by Lars Michelsen

ID: 8067 Title: Delay service notification when host comes up Component: cmc Level: 1 Class: Bug fix Version: 1.2.6b1 When a host is DOWN and then a service of that host goes CRIT, the corresponding notification is put on hold. As soon as the host goes up again the notification would immediately be sent out. Now we rather wait for the next check of the service, in order to give it a chance to become OK again, after the host is reachable again.

Check_MK Werk 8070: Fix notification type for the end of downtimes

by Lars Michelsen

ID: 8070 Title: Fix notification type for the end of downtimes Component: cmc Level: 2 Class: Bug fix Version: 1.2.5i6 When a downtime ends the CMC used to set the NOTIFICATION_TYPE to <tt>DOWNTIMESTOPPED</tt>, while Nagios uses <tt>DOWNTIMEEND</tt>. This leads to an invalid notification classification in the rule based notification, so that instead of the type <i>Downtime Start or End</i> a normal altert type was being assumed. That has been fixed now.

Check_MK Werk 8063: Recover broken RRD files after disk-full situation

by Lars Michelsen

ID: 8063 Title: Recover broken RRD files after disk-full situation Component: cmc Level: 1 Class: Bug fix Version: 1.2.6b1 In a situation where you are ouf of disk space RRDTool will create empty <tt>*.rrd</tt> files. The CMC considered these later as existing and would not attempt to recreate them. This has been fixed and zero-sized RRD files are considered to be non-existant now.

Check_MK Werk 8064: Remove bogus error messages in cmc.log when core restarts

by Lars Michelsen

ID: 8064 Title: Remove bogus error messages in cmc.log when core restarts Component: cmc Level: 1 Class: Bug fix Version: 1.2.6b1 When you restart the core and there are currently running Check_MK checks that have to be aborted then the CMC logfile prints a line: F+:cmc.log 2014-12-01 10:57:26 [5] Check helper [24933] exited with status 1 F-: This line has been reclassified from error (<tt>[3]</tt>) to notice (<tt>[5]</tt>). This will avoid bogus error message in the logfile monitoring of the Check_MK appliances.

Check_MK Werk 8065: Savely direct any verbose or diagnostic output from check_mk or checks to cmc.log

by Lars Michelsen

ID: 8065 Title: Savely direct any verbose or diagnostic output from check_mk or checks to cmc.log Component: cmc Level: 2 Class: New feature Version: 1.2.6b1 If any check outputs something to stdout or stderr (which it should not do in production mode) or if a function in the check_mk code (such as inline SNMP) outputs data to stdout or stderr, then this will now savely be logged to the CMC log with the classification "warning". This will allow easier debugging and error handling. Also the logfile <tt>cmc-helper.log</tt> will no longer be created. Messages go into <tt>cmc.log</tt> instead.

Check_MK Werk 8057: Avoid SmartPING timeouts in situation of high disk I/O

by Lars Michelsen

ID: 8057 Title: Avoid SmartPING timeouts in situation of high disk I/O Component: cmc Level: 2 Class: Bug fix Version: 1.2.5i5 In situations where the operating system in in high disk I/O and many processes run into disk wait, the micro core seemed sometimes to register PING timeouts. That was simply due to the fact that the core itself was delayed and thought the PING packages didn't arrive in time. This has now been fixed, by assuming that when checking the PING timeout taking into account the time since the last check: CMC assumes now that all PING must have arrived directly at the beginning of the current interval, not at the end.

Check_MK Werk 8058: Fixed problems with SNMP GET where non requested OIDs were answered

by Lars Michelsen

ID: 8058 Title: Fixed problems with SNMP GET where non requested OIDs were answered Component: inline-snmp Level: 1 Class: Bug fix Version: 1.2.5i5 Some devices do not really care about the requested SNMP OID when they do not know this OID. It happened here that a device simply answered with the next known OID. This confused several of our checks. The SNMP GET does now verify the OID provided with the response against the requested OID and ignores non matching responses.
