Check_MK Werk 2188: Rule based notification now allow match for notification comment

by Mathias Kettner

ID: 2188 Title: Rule based notification now allow match for notification comment Component: Notifications Level: 1 Class: New Feature Version: 1.2.7i1 A new condition allows a match on the notification comment. This comment is supplied in custom notifications - never in normal notifications. This allows to create custom commands that e.g. open tickets by creating custom notifications with a certain text in the comment.

Check_MK Werk 2187: Avoid CLOSE_WAIT sockets for agent connection in case of timeouts

by Mathias Kettner

ID: 2187 Title: Avoid CLOSE_WAIT sockets for agent connection in case of timeouts Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.7i1 In case of agent timeouts (per default this is set to 60 seconds) when using keep alive mode (as the CMC does) socket connections could be left over in <tt>CLOSE_WAIT</tt> state. This is due to a file descriptor not being closed correctly by Python. This has been fixed.

Check_MK Werk 2186: check_mk_agent.aix: use GNU df in order to exclude NFS for filesystem monitoring

by Mathias Kettner

ID: 2186 Title: check_mk_agent.aix: use GNU df in order to exclude NFS for filesystem monitoring Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i1 If the <tt>df</tt> command from the GNU <tt>coreutils</tt> is present at <tt>/usr/opt/freeware/bin/df</tt> then that is being used instead of the AIX <tt>df</tt> command. This avoids a hanging agent in case of hanging NFS mounts.

Check_MK Werk 2184: statgrab_mem: converted to the same logic as the other memory checks

by Mathias Kettner

ID: 2184 Title: statgrab_mem: converted to the same logic as the other memory checks Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i1 The check plugin <tt>statgrab_mem</tt> now uses the same implementation as <tt>solaris_mem</tt> and many other memory checks. That makes the output compatible. Note: This change is incompatible since existing rules for memory levels do not apply any longer. Now the same WATO rule set as for other memory checks is being used. Please create new rules if you have the need for custom levels.

Check_MK Werk 2183: ps: allow levels of used RAM in percentage of total RAM of host

by Mathias Kettner

ID: 2183 Title: ps: allow levels of used RAM in percentage of total RAM of host Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i1 You can now specify the levels for the memory usage of a process or group of processes in relation to the total RAM memory of a host. This makes it easier to find memory consuming processes in general, without the need for different levels for every single host. Note: these levels only work if the agent output provides information about the total memory. This is the case for at least the usual agents for Linux, Windows and Solaris.

Check_MK Werk 1954: fileinfo / fileinfo.group: Fixed discovery function for fileinfo groups and equalize agent output of fileinfo agents

by Sven Rueß

ID: 1954 Title: fileinfo / fileinfo.group: Fixed discovery function for fileinfo groups and equalize agent output of fileinfo agents Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.2.7i1 Discovery function now handles the agent output as followed: <ul> <li>File Pattern match: For every matching file a new item is returned and a new service is created.</li> <li>File Pattern mismatch: This pattern will be ignored. No item is returned and no service is created.</li> <li>Group Pattern match or mismatch: For every group a new item is returned and a new service is created.</li> </ul> Supported agents on Windows, Linux, FreeBSD, MacOSX and Solaris now return the same agent output as followed: <Searchpattern or Absolute file path>|<Filesize or "missing">|<Modification time of file>

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 1900: mk_oracle: added oracle session environment

by Bruhns＠mathias-kettner.de

ID: 1900 Title: mk_oracle: added oracle session environment Component: Checks & Agents Level: 1 Class: New Feature Version: 1.2.7i1 The plugin set some session parameters after login to Oracle. This is useful for environments with very special init.ora parameters which caused some performance problems in mk_oracle. The new function could be disabled with the following parameter in mk_oracle.cfg: <tr>DISABLE_ORA_SESSION_SETTINGS=1</tr>
