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.

Check_MK Werk 1903: mk_oracle: Remote Monitoring of Oracle Databases

by Bruhns＠mathias-kettner.de

ID: 1903 Title: mk_oracle: Remote Monitoring of Oracle Databases Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 mk_oracle got a major improvement in monitoring Oracle Databases. This new option allows monitoring a database from another host with a running check_mk_agent. H2: Requirements You need an Oracle Client from Oracle to use this feauture. The Oracle Instant Client with SQLPlus is a required minimum. You could use an existing Oracle installation as environment for mk_oracle as well. The plugin sends the data with piggyback. Please keep in mind, that the agent from the host with mk_oracle is responsible for the piggyback data. If you put the Check_MK check in downtime you'll put all other database checks from mk_oracle in a downtime as well. H2: Configuration You need an Oracle Client. If ORACLE_HOME is not set in the login shell of root, you need to add the ORACLE_HOME variable to mk_oracle.mk. Add the following lines to <tt>mk_oracle.cfg</tt>. The path is an example for the RPM Instant Client from Oracle for 64bit. <tt>ORACLE_HOME=/usr/lib/oracle/11.2/client64</tt> <tt>REMOTE_INSTANCE_1_omd110=check_mk:check_mk:::::XE:11.2</tt> <tt>REMOTE_INSTANCE_2_omd110=check_mk:check_mk:::::XE2:11.2</tt> Definition of a REMOTE_INSTANCE: <tt>REMOTE_INSTANCE_<Number>_<piggyback Hostname>=<Configuration String></tt> The definition of the database connection is as follows. <tt><username>:<password>:<sysdba>:<port>:<Database hostname>:<reserved for future use>:<ORACLE_SID>:<ORACLE-Release></tt> Notes regarding <tt>REMOTE_INSTANCE_x</tt> You need to make sure, that the name of the variable including the hostname is unique for every database in <tt>mk_oracle.cfg</tt>. Only 3 '_' are allowed in front of the piggyback hostname. Otherwise the plugin won't work correctly. The Oracle Release must be 9.2, 10.1, 10.2, 11.1, 11.2 or 12.1. No other values are allowed. Don't forget to use the testmode before starting the inventory on the monitoring host. More details could be found on the documentation at Check_MK: https://mathias-kettner.de/checkmk_oracle.html The testmode is compatible with the remote mode. Details with an example are shown in the documentation. H2: Incompatible change: The compatibility against old sqlplus.sh has been removed. Please remove an exiting sqlplus.sh and configure the <tt>mk_oracle.cfg</tt>. This change is a requirement for the new remote monitoring option and the only reason for this change. There is nothing to do when <tr>sqlplus.sh</tr> was not used before this Werk.

Check_MK Werk 2061: DB2 monitoring: Additional checks for AIX (and presumably linux)

by Andreas Boesl

ID: 2061 Title: DB2 monitoring: Additional checks for AIX (and presumably linux) Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 This werk introduces the new agent plugin mk_db2.aix which can be installed on aix systems in the agents plugins directories. It is very likely that it runs on linux systems as well. It is able to run queries over multiple DB2 instances. The plugin output is processed by the following new checks <table> <tr><th>Check</th><th>Description</th><th>Limits configurable</th></tr> <tr><td>db2_backup</td><td>Time since last database backup</td><td>X</td></tr> <tr><td>db2_bp_hitratios</td><td>Bufferpool Hitratios</td><td></td></tr> <tr><td>db2_connections</td><td>Number of database connections</td><td>X</td></tr> <tr><td>db2_counters</td><td>Deadlocks and Lockwaits per Second</td><td>X</td></tr> <tr><td>db2_logsize</td><td>Size and growth of database logfile</td>X<td></td></tr> <tr><td>db2_tablespaces</td><td>Size and growth of tablespaces</td>X<td></td></tr> <tr><td>db2_sort_overflow</td><td>Percentual sort overflow</td><td>X</td></tr> <tr><td>db2_version</td><td>Displays DB2 version</td><td></td></tr> </table>

Check_MK Werk 2104: aix_if: new agent section and check

by Goetz Golla

ID: 2104 Title: aix_if: new agent section and check Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 This aix check_mk_agent has a new section aix_if extracting more information about network interfaces than the previous lnx_if section. A new interface check for AIX named aix_if has also been created given more useful information. As long as you do not replace the check_mk_agent on your AIX systems, nothing will change. When you replace the agent with the new one, you will have to redo the service discovery. Interfaces will reappear with the same service description, but with more information about the NIC.
