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 2248: The Event Console can now translate incoming SNMP traps

by Lars Michelsen

ID: 2248 Title: The Event Console can now translate incoming SNMP traps Component: Event Console Level: 2 Class: New Feature Version: 1.2.7i1 The Event Console can be configured to receive SNMP traps. In the past it only extracted all raw OIDs and values from the incoming trap and putting them together in the event message as they come in. Now it is possible to use SNMP MIB files to let the Event Console translate the OIDs, values and units contained in the traps. This feature is disabled by default. You need to enable the Event Console and the SNMP trap handling by using <tt>omd config</tt> in OMD environments. Then you need to enable the trap translation in Event Console > Settings by setting Translate SNMP traps to on. Finally you need to activate the pending EC-Change. Now all available MIBs will be used to translate the incoming traps. You can now upload custom MIB files using the MIB management page at Event Console > SNMP MIBs which will be used for translation after reloading the Event Console.

Check_MK Werk 2204: Inventory of switch ports, allows searching for unused ports

by Mathias Kettner

ID: 2204 Title: Inventory of switch ports, allows searching for unused ports Component: HW/SW-Inventory Level: 2 Class: New Feature Version: 1.2.7i1 The Check_MK HW/SW-Inventory now collections information via SNMP. The first two implemented plugins are for the basic SNMP information and for the list of network interfaces (switch ports). The latter are available in a new status view where you can search ports for various criteria - e.g. all ports where the type is Ethernet and that are down for at least one month. All you need to do is to active the HW/SW-Inventory on those devices.

Check_MK Werk 2175: Added icon uploader, unified icon selection

by Lars Michelsen

ID: 2175 Title: Added icon uploader, unified icon selection Component: Multisite Level: 2 Class: New Feature Version: 1.2.7i1 Check_MK makes use of icons in views and dashboards, but it is also possible to add a custom icon to hosts or services for e.g. showing up the type of the device in a graphical way. This version also adds the option to register custom icons and actions to host and services. This change unifies the handling of icons used in such places. We implemented an icon selector which is used everywhere were you can select an icon. This icon selector groups the icons together in categories for more comfortable selection. We added an icon upload mechanism which gives you the option to manage your custom icons using WATO. You can find it in the top level navigation of WATO. All icons are now loaded from a fixed location, in OMD environments this is <tt>share/check_mk/web/htdocs/images/icons</tt> for the icons distributed by us and <tt>local/share/check_mk/web/htdocs/images/icons</tt> for your custom icons. Implementation detail: The category of an icon is saved directly in the icon image. It is stored in the PNG comment metadata.

Check_MK Werk 2174: Added action popup to host & service views, supporting custom actions now

by Lars Michelsen

ID: 2174 Title: Added action popup to host & service views, supporting custom actions now Component: Multisite Level: 2 Class: New Feature Version: 1.2.7i1 Each host and service has several icons showing up in the web GUI to either provide options to perform actions or visualizing the state of the object. Now we reworked the whole thing a bit by adding a popup menu which is groups together the actions for an object. This aims to reduce the number of icons shown up in list views. By default the icon column is now showing the popup menu trigger icon which can be left clicked to open the popup menu and the graph icon if a host or service has performance data available. The column is also showing all state related icons. Former versions already allowed users to extend the web GUI with so called in python written icon plugins. This is still possible. But now, we added the option to easily configure basic actions using WATO. The configuration is split into two steps: a) You need to basically configure your custom actions This is done via the option Custom icons and actions which can be found in the Status GUI (Multisite) tab of the Global Settings. First you need to choose an unique identifier for your action. Then you can either configure simple icons providing some kind of information, for example the type of the system, by configuring just an icon and the title. If you like to add a custom action, for example a link to the web interface of one of your devices, you can configure an action URL where you can use some basic macros: <ul> <li>$HOSTNAME$: Contains the name of the host</li> <li>$SERVICEDESC$: Contains the service description (in case this is a service)</li> <li>$HOSTADDRESS$: Contains the network address of the host</li> </ul> b) Assign the actions to your objects After you configured at least one custom action, you can use the rules Custom icons or actions for hosts in status GUI and Custom icons or actions for services in status GUI to assign your custom actions to your hosts and services.
