Check_MK Werk 3449: The host alias can now be used in BI aggregates

by Lars Michelsen

ID: 3449 Title: The host alias can now be used in BI aggregates Component: BI Level: 2 Class: New Feature Version: 1.2.9i1 When matching for hosts in BI aggregations it is now possible to match hosts with regular expressions by their host alias instead of the host name. Additionally it is now possible to use the host alias in the titles of the aggregations. Instead of using $1$ for matchin the host name or the host alias, you can now use the variables $HOSTNAME$ or $HOSTALIAS$ to use them in your BI rules.

Check_MK Werk 3388: Event Console can now process SNMPv3 traps

by Lars Michelsen

ID: 3388 Title: Event Console can now process SNMPv3 traps Component: Event Console Level: 2 Class: New Feature Version: 1.2.9i1 The Event Console can now process SNMPv3 traps send with SNMPv3. To be able to receive the traps, you will have to configure the SNMPv3 credentials to be used for decrypting the received traps. This can be done in the Event Console configuration using the option <i>Credentials for processing SNMPv3 traps</i>. For each sending server you need to configure the credentials and the systems engine ID which is normally generated automatically by the SNMP device. Some devices also support setting engine IDs on your own. However, the SNMPv3 specification requires that each SNMP device has it's own unique engine ID. To be able to decrypt the traps you need to configure this engine ID together with the other SNMPv3 credentials for each trap sending device.

Check_MK Werk 3418: Do not send host notifications if a service group is required

by Mathias Kettner

ID: 3418 Title: Do not send host notifications if a service group is required Component: Notifications Level: 2 Class: Bug Fix Version: 1.2.9i1 If you set a match condition on the service groups then for host notifications this condition was ignored. But a host cannot be in any service group so now if you use this condition then the rule will never match for host notifications. This should be the way that you expect this.

Check_MK Werk 3386: AIX agent: Cached local scripts / plugins need to be configured in seconds

by Lars Michelsen

ID: 3386 Title: AIX agent: Cached local scripts / plugins need to be configured in seconds Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.9i1 When using cached executin of local scripts or agent plugins (putting scripts in subdirectories named like the execution interval) with the AIX agent, the directory names were interpreted as minutes which was not consistent with the other agents. This has now been changed to be consistently interpreted as seconds. You will have to rename your directories to the current name multiplied with 60 to execute the plugins again in the expected interval.

Check_MK Werk 3027: mtr (Matt's traceroute): New agent plugin

by Andreas Boesl

ID: 3027 Title: mtr (Matt's traceroute): New agent plugin Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.9i1 mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool. For further information have a look at the mtr manpage. This plugin collects data for every hop to the destination address and creates a plethora of performance values for round trip average, package loss and standard deviation. Keep in mind that services for this new check require quite a large amount of RRD space, due to the large number of performance values. Roughly ~23MB for 10 network hops to a target destination.

Check_MK Werk 3396: Change default setting of Precompile aggregations on demand to ON now

by Mathias Kettner

ID: 3396 Title: Change default setting of Precompile aggregations on demand to ON now Component: BI Level: 2 Class: New Feature Version: 1.2.9i1 The global setting {{Precompile aggregations on demand}} improves the performance of BI in case where not all aggregations are needed at once. This is especially true for the case of single-host aggregations. This setting now exists for a long time and we have finally regarded that feature as stable enough in order to make it the default. We might remove the setting from WATO totally in future.

Check_MK Werk 3395: Fix performance issue when many BI aggregations are active

by Mathias Kettner

ID: 3395 Title: Fix performance issue when many BI aggregations are active Component: Multisite Level: 2 Class: Bug Fix Version: 1.2.9i1 If you have created 1000 or more aggregations and show a view with many hosts or services than you could get massive performance and memory problems in your Apache process. The reason is the computation of the BI icon in the drop down menus of hosts and services. This was only done in order to check the visibility of the menu itself. The menu is now always visible and thus the computation is not longer neccessary.

Check_MK Werk 3394: Availability: Annotations can now be used to reclassify the scheduled downtime status

by Mathias Kettner

ID: 3394 Title: Availability: Annotations can now be used to reclassify the scheduled downtime status Component: Reporting & Availability Level: 2 Class: New Feature Version: 1.2.9i1 The availability computation of hosts and services now allows to use the existing {{Annotations}} in order to reclassify the annotated periods as having been in scheduled downtime or even as not having been in scheduled downtime. That way you can fix your figures in case one has forgotten to enter a scheduled downtime in the past or in the case that scheduled downtimes were just used in order to disable notifications (but the breakdown was in fact real and not scheduled). Availability of BI aggregations currently does not support annotations or any reclassifications. Neither does it honor reclassifications in the underlying host and service history.

Check_MK Werk 3328: Default cloned views to be not public

by Mathias Kettner

ID: 3328 Title: Default cloned views to be not public Component: Multisite Level: 2 Class: New Feature Version: 1.2.9i1 If you create a view as a clone from an existing view than the new view defaults <b>not</b> to be public. Previously the public-flag was cloned as well. That could lead into trouble by an admin overriding the views of others by that way.
