Check_MK Werk 2843: Hanging notification scripts could prevent all other notifications

by Lars Michelsen

ID: 2843 Title: Hanging notification scripts could prevent all other notifications Component: Notifications Level: 2 Class: Bug Fix Version: 1.2.7i4 Notification scripts are assumed to finish within short time like a couple of seconds. If a notification script takes longer or is hanging for ever, it prevent Check_MK from sending out other notifications. So one hanging notification could prevent all others. This has been fixed by introducing a global notification plugin timeout. All notification plugins which take more than 60 seconds will be killed so that other notifications can be done again. If you need a different timeout, you can configure it using the global setting "Notification plugin timeout".

Check_MK Werk 0973: Renaming of hosts via WATO

by Mathias Kettner

ID: 0973 Title: Renaming of hosts via WATO Component: WATO Level: 2 Class: New Feature Version: 1.2.5i3 WATO has now a new function Rename Host. You will find a button with that name in the Properties of a host. It allows a renaming of an existing host. Before you can use that feature you need to have all changes activated, so nothing is pending. Renaming a host is a complex precedure that will not only rename the host in WATO, but also in: <ul> <li>all rules from Host & Service Parameters</li> <li>cluster's node definitions</li> <li>a host's parent definitions</li> <li>Business Intelligence rules</li> <li>notification rules (both rule based and flexible notifications)</li> <li>internal Check_MK data like caches and performance counters</li> <li>auto-disovered services of the host</li> <li>logfile information of logwatch plugin</li> <li>stored SNMP walks</li> <li>RR databases with performance data</li> <li>RRD updates in journal of RRD Cache</li> <li>spool files of PNP4Nagios</li> <li>NagVis maps</li> <li>monitoring history entries (events and availability)</li> <li>the current monitoring state (including ackowledgements and downtimes)</li> </ul> Please note that renaming of a host involves a temporary stop of the monitoring core. This is neccessary in order to avoid situation where the old and the new name of a host is being used at the same time.

Check_MK Werk 2756: SNMP: Generalized error handling of emtpy info for SNMP checks

by Lars Michelsen

ID: 2756 Title: SNMP: Generalized error handling of emtpy info for SNMP checks Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.7i4 This change changes the way empty data for SNMP checks is handled. In previous version each SNMP check had to deal with the fact that the SNMP agent could respond with an empty response (info = []). This situation can better be handled in the Check_MK SNMP engine which catches this issue now before calling the discovery/check function of the check. The error is then reported as missing info like for the Check_MK Agent based checks. There might be some special SNMP checks which need to treat this case of empty data on its own. These checks now need to declare the attribute <tt>handle_empty_info</tt> in the <tt>check_info</tt>.
