Check_MK Werk 2137: diskstat: new implementation of Linux Disk IO check

by Mathias Kettner

ID: 2137 Title: diskstat: new implementation of Linux Disk IO check Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 The <tt>diskstat</tt> check for Linux has been reimplemented from scratch. It now gets much more specific metrics information like average wait time, IO queue length, latency, IOs per seconds und more. Six graphs are being created. Note: this check is new parametrized by a new rule set in WATO. You need to redo your configuration of this check, sorry. Also if you have a very old legacy setup with two seperate checks for read and write, you also need to rediscover. These checks are not longer supported.

Check_MK Werk 2057: New checks for postgreSQL monitoring

by Andreas Boesl

ID: 2057 Title: New checks for postgreSQL monitoring Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 With this update the agent plugin mk_postgres now reports additional information, which will be processed by these new checks: <table> <tr><th>Check</th><th>Description</th><th>Limit configurable</th></tr> <tr><td>postgres_bloat</td><td>Shows size of table and index bloat</td><td>X</td></tr> <tr><td>postgres_conn_time</td><td>Time to connect to database</td><td></td></tr> <tr><td>postgres_connections</td><td>Number of connections to database</td><td>X</td></tr> <tr><td>postgres_locks</td><td>Number of ShareAccess and ExclusiveLocks</td><td>X</td></tr> <tr><td>postgres_query_duration</td><td>Displays longest running query</td><td></td></tr> <tr><td>postgres_stats</td><td>Time of last VACUUM and ANALYZE</td><td>X</td></tr> <tr><td>postgres_version</td><td>Displays PostgreSQL version</td><td></td></tr> </table> Note: You have to update the agent plugin mk_postgres on the target host.

Check_MK Werk 2136: Unify headers of Host/Service rules, EC rules and notification rules

by Mathias Kettner

ID: 2136 Title: Unify headers of Host/Service rules, EC rules and notification rules Component: WATO Level: 2 Class: New Feature Version: 1.2.7i1 All three types of rules now have a common header with description, command and documentation URL. The section has been renamed from General Properties or Additional options to Rule Properties. In the host and service rules the existing comment information is being used as description if the description is empty. This is in order to be compatible with the existing configuration where no description field existed.

Check_MK Werk 2041: Notification Spooler can now handle incoming and outgoing persistent TCP connections

by Mathias Kettner

ID: 2041 Title: Notification Spooler can now handle incoming and outgoing persistent TCP connections Component: Notifications Level: 2 Class: New Feature Version: 1.2.7i1 The Check_MK Notification Spooler (<tt>mknotifyd</tt>) has completely been rewritten. It now: <ul> <li>uses persistent TCP connections instead of connecting for each notifiction</li> <li>can use outgoing TCP connections for receiving notifictions</li> <li>can handle an arbitrary number of parallel connctions</li> <li>monitors connections with heart beats</li> <li>is being monitored by two new checks for the general state and for each connection</li> </ul> The global configuration for the spooler has changed. Your existing settings are still supported but have vanished from WATO. As soon as you create a new configuration that will override your legacy configuration. The new checks that monitor the spooler require an update of the Check_MK Agent for Linux on the Check_MK server. It needs OMD based installaions paths. All spoolers will automatically be discovered. The new checks are <tt>mknotifyd</tt> and <tt>mknotifyd.connection</tt>. The spooler write messages into <tt>var/log/mknotifyd.log</tt>. There are three log levels, which can be configured in the global settings of the spooler. We propose starting with the highest log level. Also a file <tt>var/log/mknotifyd.log</tt> is being written every 20 seconds. It shows the state of the spooler and its connections. This is being used for the monitoring of the spooler.

Check_MK Werk 2042: Services are now sorted in a natural way, this affects services containing numbers

by Mathias Kettner

ID: 2042 Title: Services are now sorted in a natural way, this affects services containing numbers Component: Multisite Level: 2 Class: New Feature Version: 1.2.7i1 Previously services would be sorted alphabetically, e.g. <tt>foo1</tt>, <tt>foo10</tt>, <tt>foo11</tt>, ... <tt>foo2</tt>, <tt>foo3</tt>, etc. Now numbers within the descriptions are being detected by a smart algorithm and the sorting is then <tt>foo1</tt>, <tt>foo2</tt>, ... , <tt>foo9</tt>, <tt>foo10</tt>, <tt>foo11</tt>, just as you would expect.

Check_MK Werk 2052: winperf_if: Now able to automatically group teamed interfaces and more

by Andreas Boesl

ID: 2052 Title: winperf_if: Now able to automatically group teamed interfaces and more Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 The winperf_if check is now able to detect teamed interfaces. This information is provided by the updated wmic_if.ps1 plugin. Right now, the teamed interfaces are no longer listed separately. There will be a configuration option soon which allows you to configure this behaviour. H2: Incompatible change The service descriptions for this check did never show the human readable/editable interface name - the NetConnectionID. This has been fixed. This information is now provided in the alias information of each interface. If you have used the configuration option <tt>if_inventory_uses_alias</tt>, the interface will now have a different name. Therefore the service description changes and the performance data will get lost. A workaround for this problem is to use <tt>if_inventory_uses_description</tt> instead.... For windows hosts the settings <tt>if_inventory_uses_alias</tt> and <tt>if_inventory_uses_description</tt> meant the same in previous version. With this update the meaning of <tt>if_inventory_uses_alias</tt> has changed.

Check_MK Werk 2083: Added Siemens PLC (SPS) monitoring

by Lars Michelsen

ID: 2083 Title: Added Siemens PLC (SPS) monitoring Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.7i1 We added a special agent {agent_siemens_plc} which is using SNAP7 to fetch data from a Siemens PLC (SPS) device. You can use it do read memory areas from the agent, parse and interpret them, for example you can configure to read and integer from memory location X and handle it as temperature value in celsius. For the moment we added a temperature check, others will follow.

Check_MK Werk 2022: SNMP: Fixed handling of backslashes in SNMP data

by Lars Michelsen

ID: 2022 Title: SNMP: Fixed handling of backslashes in SNMP data Component: Checks & Agents Level: 2 Class: Bug Fix Version: 1.2.7i1 Some checks like the hr_fs checks e.g. create services with backslashes in the service descriptions when monitoring windows filesystems. Those services were named "Filesystem c:\\..." for example, which was using a double backslash which is wrong. This behaviour has now been changed to just use a single slash. With this change your services will be reported as UNKNOWN when you have such services with double backslashes in their names. You will then need to rediscover the services to get them with just a single slash. If you like to keep the performance graph history, you will need to migrate them on your own.
