by Lars Michelsen

ID: 5949 Title: cpu.threads cpu.load: Disabled in docker container contexts Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 These checks do not make sense in the context of a docker container. The agent is now skipping this section when executed in a container.

Check_MK Werk 5948: docker_container_mem: Docker container specific memory checking

by Lars Michelsen

ID: 5948 Title: docker_container_mem: Docker container specific memory checking Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 Instead of using the default linux memory check (mem), Check_MK is now using the container specific memory check. The main reason is that the memory information in the container is not available through <tt>/proc/meminfo</tt> as usual. The memory data is available through the kernels cgroup interface which is available in the containers context below <tt>/sys/fs/cgroup/memory/memory.stat</tt> The features of both checks are exactly the same.

Check_MK Werk 5753: mk_postgres: reduce the amount of psql sessions opened by the plugin

by Tom Baerwinkel

ID: 5753 Title: mk_postgres: reduce the amount of psql sessions opened by the plugin Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 Previously, the number of psql sessions scaled linearly with the number of databases. Now the number of psql sessions opened by the plugin is constant. Additionally, the sessions of some sections were combined to further reduce the total number of psql sessions.

Check_MK Werk 5769: site_object_counts: New check which collects information about the amount of different host types or used check commands of OMD sites

by Simon Betz

ID: 5769 Title: site_object_counts: New check which collects information about the amount of different host types or used check commands of OMD sites Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 To make this check work please install the {{mk_site_object_counts}} agent plugin and specify host tags or check commands within the {{site_object_counts.cfg}} configration file. The following options are available: <table> <tr><td>{TAGS}</td><td>global host tags</td></tr> <tr><td>{SERVICE_CHECK_COMMANDS}</td><td>global check commands</td></tr> <tr><td>{SITES}</td><td>restriction to specified sites</td></tr> <tr><td>{TAGS_$SITENAME}</td><td>site specific host tags</td></tr> <tr><td>{SERVICE_CHECK_COMMANDS_$SITENAME}</td><td>site specific check commands</td></tr> </table> The agent plugin is executed if and only if OMD is installed and there's a configuration file. Sites which provide an opened Livestatus socket {/omd/sites/$SITENAME/tmp/run/live} are taken into account. Without the restrictive option {SITES} all sites on that server are considered which satisfy above conditions. If more than one value is assigned they have to be separated by one space, eg. <ul> <li>{TAGS=prod snmp}</li> <li>{SERVICE_CHECK_COMMANDS_sitename=kernel lnx_if}</li> <ul> H3:Example 1 F+:site_object_counts.cfg TAGS=snmp SERVICE_CHECK_COMMANDS=if F-: With this configuration the agent plugin returns the amount of all SNMP hosts and the amount of all interface services of the type {if} of all sites. H3:Example 2 F+:site_object_counts.cfg SITES=site_a site_b TAGS=snmp SERVICE_CHECK_COMMANDS=if F-: With this configuration the agent plugin returns the amount of all SNMP hosts and the amount of all interface services of the type {if} of the sites {site_a} and {site_b}. H3:Example 3 F+:site_object_counts.cfg TAGS_site_a=snmp SERVICE_CHECK_COMMANDS_site_a=if TAGS_site_b=agent SERVICE_CHECK_COMMANDS_site_b=lnx_if F-: With this configuration the agent plugin returns <ul> <li>the amount of all SNMP hosts and the amount of all interface services of the type {if} of the site {site_a} and</li> <li>the amount of all agent-based hosts and the amount of all Linux interface services of the type {lnx_if} of the site {site_b}.</li> </ul> H3:Example 4 F+:site_object_counts.cfg TAGS=prod SERVICE_CHECK_COMMANDS=omd_apache omd_status TAGS_site_a=snmp SERVICE_CHECK_COMMANDS_site_a=if TAGS_site_b=agent SERVICE_CHECK_COMMANDS_site_b=lnx_if F-: With this configuration the agent plugin returns <ul> <li>the amount of all productive hosts and services of type {omd_apache} and {omd_status} of all sites.</li> <li>additionaly the amount of all SNMP hosts and the amount of all interface services of the type {if} of the site {site_a} and</li> <li>additionaly the amount of all agent-based hosts and the amount of all Linux interface services of the type {lnx_if} of the site {site_b}.</li> </ul> H3:Example 5 F+:site_object_counts.cfg SITES=site_a site_b site_c TAGS=prod SERVICE_CHECK_COMMANDS=omd_apache omd_status TAGS_site_a=snmp SERVICE_CHECK_COMMANDS_site_a=if TAGS_site_b=agent SERVICE_CHECK_COMMANDS_site_b=lnx_if F-: With this configuration the agent plugin returns <ul> <li>the amount of all productive hosts and services of type {omd_apache} and {omd_status} of the sites {site_a}, {site_b} and {site_c}.</li> <li>additionaly the amount of all SNMP hosts and the amount of all interface services of the type {if} of the site {site_a} and</li> <li>additionaly the amount of all agent-based hosts and the amount of all Linux interface services of the type {lnx_if} of the site {site_b}.</li> </ul>

Check_MK Werk 5944: Fixed broken HTTP header auth for not yet existing users

by Lars Michelsen

ID: 5944 Title: Fixed broken HTTP header auth for not yet existing users Component: Multisite Level: 1 Class: Bug fix Version: 1.5.0i4 This was broken since ~1.5.0i3. When a user which has not been created in Check_MK before is being authenticated using the optional HTTP header authentication and logged in using the "default user profile", some host- and service views were not working as expected. They were showing some exception like "KeyError: u'<USER>'". A workaround in the affected versions is to create the user accounts before the user try to access the GUI.
