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 1150: netstat: new check for monitoring TCP/UDP connections and Linux and AIX

by Mathias Kettner

ID: 1150 Title: netstat: new check for monitoring TCP/UDP connections and Linux and AIX Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.5i6 The check does the same as <tt>win_netstat</tt> and also uses the same WATO rule. You need to deploy the agent plugin <tt>netstat.linux</tt> or <tt>netstat.aix</tt>.

Check_MK Werk 1148: Allow execution of actions when cancelling events

by Mathias Kettner

ID: 1148 Title: Allow execution of actions when cancelling events Component: Event Console Level: 2 Class: New Feature Version: 1.2.5i6 The Event Console now allows to attach actions to the cancelling of events. This can for example be helpful if you have an action that opens a trouble ticket in an external system. When a cancelling event arrives you can have executed an action that also cancels the according trouble ticket. When events are cancelled then several data fields of the event are being replaced with data from the new event before the action is being executed. That way relevant data from the new event is available in the action script. Also the event phase is being set to <tt>closed</tt> and the state is set to 0 (OK). That way your action script can distinguish between a normal and a cancelling situation. The following fields are taken from the new (i.e. cancelling) event: <ul> <li>The text</li> <li>The time</li> <li>The time of the last occurance</li> <li>The syslog priority</li> </ul> All other fields are unchanged - including the original ID of the cancelled event.

Check_MK Werk 1100: WATO backup domains: fixed bug were excluded files still got deleted on snapshot restore

by Andreas Boesl

ID: 1100 Title: WATO backup domains: fixed bug were excluded files still got deleted on snapshot restore Component: WATO Level: 2 Class: Bug Fix Version: 1.2.5i6 It is possible to configure a backup domain so that certain files are not packed into the snapshot. As a result, upon restore these file should not get deleted.. This mechanism did not work correctly.

Check_MK Werk 1147: upc_capacity, ups_socomec_capacity: Fix checking of battery left levels

by Mathias Kettner

ID: 1147 Title: upc_capacity, ups_socomec_capacity: Fix checking of battery left levels Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.5i6 The fixes the execution of the levels for Time left on battery. These levels where internally compared against the <t>Time running on battery - which is obviously quite the opposite. Example: If you configure a warning level of <tt>50</tt> minutes for Time left on battery then the check gets critical if the estimated remaining battery time is 50 minutes or less.

Check_MK Werk 1373: Do not ouput complete command line when datasource programs fail

by Mathias Kettner

ID: 1373 Title: Do not ouput complete command line when datasource programs fail Component: Core & Setup Level: 2 Class: Security Fix Version: 1.2.5i6 When executing a datasource program like <tt>agent_vsphere</tt> fails, then Check_MK used to output the complete command line as plugin output of the Check_MK active check as part of an error message. The commandline could contain passwords - however. So this has now been changed into just outputting the path to the executable (e.g. <tt>/omd/sites/mysite/share/check_mk/agents/special/agent_vsphere</tt>).

Check_MK Werk 1144: blade_bx_temp, dell_chassis_temp, emerson_temp, ibm_svc_enclosurestats, ups_bat_temp: rename service description

by Mathias Kettner

ID: 1144 Title: blade_bx_temp, dell_chassis_temp, emerson_temp, ibm_svc_enclosurestats, ups_bat_temp: rename service description Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.5i6 Rename service description of these checks. They now all begin with <tt>Temperature</tt>, such as is custom for all Check_MK checks. Beware: new graphs will be created. If these services are target of WATO or BI rules you might need to adjust them. Your WATO configuration for levels should work without change.

Check_MK Werk 1010: chrony: new check for NTP synchronization via chrony on Linux

by Mathias Kettner

ID: 1010 Title: chrony: new check for NTP synchronization via chrony on Linux Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.5i6 This check does the same as the existing {ntp.time} check, but is for cases when {chrony} is being used instead of the {ntpd}. It does not support measuring jitter, however.

Check_MK Werk 1097: windows_agent: preventing missing agent sections on first query

by Andreas Boesl

ID: 1097 Title: windows_agent: preventing missing agent sections on first query Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.5i6 The windows agent did not report all sections on the first request(s) after its startup, if some plugins were configured to run asynchronous. This has been fixed. During startup, the agent now always executes the ASYNC scripts first and waits for them to finish. After the scripts are finished, it starts listening to the tcp port.

Check_MK Werk 0647: printer_input, printer_output: multiple fixes to algorithm for state determination and inventory function

by Goetz Golla

ID: 0647 Title: printer_input, printer_output: multiple fixes to algorithm for state determination and inventory function Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.5i6 The inventory function now considers the description of the unit if its name is not configured. This should lead to more and more meaningful items. Still, all units with empty name and description will be merged into one single service with an empty item name. The algorithm to determine the states of a unit was plain wrong, so that a nonsense collection of states were given. This has been corrected. Still several states may be derived, but they should now correctly describe the operational state of the unit. The inventory function also used the same algorithm to inventorize only units with meaningful states. Therefore some changes may be expected in the inventory of a printer as well.
