Check_MK Werk 7086: Localizations now extend shipped localizations

by Lars Michelsen

ID: 7086 Title: Localizations now extend shipped localizations Component: Multisite Level: 1 Class: New feature Version: 1.6.0i1 Locally installed localization files (local/share/check_mk/locale) may now extend the builtin localizations instead of overriding them. In previous versions the local locale file had to contain all texts that we ship with our standard localizations, for example the german localization in case one wanted to extend / change a single text. Now both, the builtin and local localization files are loaded. All texts are searched in the local file and looked up in the builtin file as fallback in case the text can not be found in the local file.

Check_MK Werk 7089: Docker container: Simplified update procedure

by Lars Michelsen

ID: 7089 Title: Docker container: Simplified update procedure Component: Site Management Level: 2 Class: New feature Version: 1.6.0i1 The update procedure of the official Check_MK containers was a bit complicated compared to the update procedure on other servers. The root cause for this was that the update always required both, the old and the new versions, while the containers are only allowed to have one version installed. This made it necessary to create an intermediate container for the update. The werk #7088 made it possible to perform an update without having access to the old version. Once we have this functionality it is now possible to replace one container with a another container. In case the version has changed, the container is performing the update during startup of the new container.

Check_MK Werk 7088: omd update can now be performed without access to source version

by Lars Michelsen

ID: 7088 Title: omd update can now be performed without access to source version Component: Site Management Level: 2 Class: New feature Version: 1.6.0i1 The "omd update" procedure, which is used to perform a version update for a site, always needed access to the previous version, the new version and the site. Since this change it is now possible to perform an update without access to the old version. This is possible becase we copy the information that are needed to the Check_MK site during site creation. This new mechanism can only be used when updating FROM a site that already implements this werk. Technical detail: <ul> <li>The meta files are saved for the first time during "omd create"</li> <li>The meta files are updated to the new version during each "omd update"</li> <li>The files are copied to the sites <tt>.version_meta</tt> directory.</li> <li>The directory <tt>/omd/versions/[version]/skel is copied.</li> <li>The file <tt>/omd/versions/[version]/share/omd/skel.permissions is copied.</li> <li>A file <tt><tt>.version_meta/version</tt> is created.</li> <li>When an update is performed, the meta files are used if they are available and up-to-date. In case they don't fit these conditiones, the previous version files need to be available as before this werk.</li> <li>

Check_MK Werk 7164: cmk-update-agent: Add timeout handling for connection to server

by Andreas Umbreit

ID: 7164 Title: cmk-update-agent: Add timeout handling for connection to server Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously, the connection from the agent updater to the Check_MK Server did not handle timeouts. This could lead to situations where the agent updater would run forever waiting for a response. This was particularly noticeable when running the agent updater under Windows, because the agent updater would fail to start over again, showing an error like <code>copying plugins\cmk-update-agent.exe to temp\cmk-update-agent.exe failed</code>. The agent updater now will cancel the connection if there is a connection timeout detected or if the connection freezes. The timeout limit is set to 120 seconds.<br> This timeout handling does not limit the overall connection time.

Check_MK Werk 7143: mk_docker.py: A new docker monitoring plugin

by Moritz Kiemer

ID: 7143 Title: mk_docker.py: A new docker monitoring plugin Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 We introduce a new plugin for docker monitoring, 'mk_docker.py'. It combines the functionality of the two deprecated plugins 'mk_docker_node' and 'mk_docker_container_piggybacked', while adding more configuration options. If you where using both plugins, you can use the new plugin in its default configuration to replace them. If you have been using only one of them, you can disable the opposite parts of the new plugin, either by using the bakery rule "Docker node and containers" or via the configuration file (please refer to the example files in agents/cfg_examples fo rmore details). The previous rule "Piggybacked docker containers" is deprecated - please set up a corresponding new one. To deploy this plugin you must have the 'docker-py' python library installed on the monitored system. You can install it using the python package manager pip (using the shell command "pip install docker-py").

Check_MK Werk 7085: Fixed parsing of special syslog messages which don't contain a host name

by Lars Michelsen

ID: 7085 Title: Fixed parsing of special syslog messages which don't contain a host name Component: Event Console Level: 1 Class: Bug fix Version: 1.6.0i1 The Event Console is now able to process syslog messages that don't contain the host name field. An example for such a message is this one: C+: Feb 13 08:41:07 pfsp: The configuration was changed on leader blatldc1-xxx to version 1.1366 by blatldc1-xxx/admin at 2019-02-13 09:41:02 CET</tt> C-: In previous versions messages like this resulted in log messages like this in the event console log (var/log/mkeventd.log): C+: 2019-02-13 09:41:07,338 [40] [cmk.mkeventd.EventServer] Got non-syslog message "Feb 13 08:41:07 pfsp: The configuration was changed on leader blatldc1-xxx to version 1.1366 by blatldc1-xxx/admin at 2019-02-13 09:41:02 CET" (need more than 1 value to unpack) Traceback (most recent call last): File "/omd/sites/ggmcmpp1/lib/python/cmk/ec/main.py", line 2916, in create_event_from_line event.update(self.parse_syslog_info(rest)) File "/omd/sites/ggmcmpp1/lib/python/cmk/ec/main.py", line 2667, in parse_syslog_info tag, message = line.split(": ", 1) ValueError: need more than 1 value to unpack 2019-02-13 09:41:07,338 [20] [cmk.mkeventd.EventServer] Parsed message: application: core_host: facility: 1 host: host_in_downtime: False ipaddress: 1.23.45.67 pid: 0 priority: 0 text: Feb 13 08:41:07 pfsp: The configuration was changed on leader blatldc1-xxx to version 1.1366 by blatldc1-xxx/admin at 2019-02-13 09:41 :02 CET time: 1550047267.34 C-: A fallback event was created that had no syslog fields set and contained the whole unparsed syslog message in the text field. If you have EC rules matching on this fallback event, you will have to change these rules to match the parsed event fields. Now that the parsing has been added, events created by such a syslog message now have the fields set as follows for our example: C+: application: pfsp core_host: facility: 1 host: 127.0.0.1 host_in_downtime: False ipaddress: 127.0.0.1' pid: 0 priority: 5 text: The configuration was changed on leader blatldc1-xxx to version 1.1366 by blatldc1-xxx/admin at 2019-02-13 09:41:02 CET time: 1550043667.0 C-: Please note that the EC uses the sender IP addresse of the syslog message to populate the host field.

Check_MK Werk 7097: diskstat.include: Read/write latency are configurable now

by Simon Betz

ID: 7097 Title: diskstat.include: Read/write latency are configurable now Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 Nearly all check plugins which use the diskstat.include in order to check disk IO provide an average value for the disk latency. Newer checks may provide values for disk read and write latency.
