Check_MK Werk 5955: df mounts: Skip docker mounts for name resolution

by Lars Michelsen

ID: 5955 Title: df mounts: Skip docker mounts for name resolution Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 When docker containers are configured to perform name resolution there are mounts at /etc/resolv.conf, /etc/hostname and /etc/hosts which are not relevant to be monitored. These checks are now always skipped.

Check_MK Werk 5945: Hosts can now be configured without IP address

by Lars Michelsen

ID: 5945 Title: Hosts can now be configured without IP address Component: Core & setup Level: 1 Class: New feature Version: 1.5.0i4 It is now possible to configure hosts in Check_MK that have no IP address configured. This is useful e.g. in case a host is only monitored using piggyback data from another host. In previous versions of Check_MK a fake IP address had to be configured for each host to prevent warning messages during config generation and during monitoring. To configure a host without IP, simply set the "IP address family" attribute of a host to "No IP". The host check of these hosts will always report "UP" by default. To override this, you can use the rule set "Host check command".

Check_MK Werk 5947: df: Exclude docker local storage mounts on docker nodes

by Lars Michelsen

ID: 5947 Title: df: Exclude docker local storage mounts on docker nodes Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 The df check is now excluding all filesystems found below <tt>/var/lib/docker</tt>, which is the default location for the docker container local storage. Depending on the used storage engine docker creates overlay filesystems and mounts below this hierarchy for the started containers. The filesystems are not interesting for our monitoring. They will be monitored from the container context.

Check_MK Werk 5946: lnx_if: Exclude veth* network interfaces on docker nodes

by Lars Michelsen

ID: 5946 Title: lnx_if: Exclude veth* network interfaces on docker nodes Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i4 The veth* network interfaces created for docker containers are now excluded by the linux agent in all cases. The interface names have no direct match with the docker container name or ID. They seem to have some kind of random nature. These container specific interfaces are not relevant to be monitored on the node. We are monitoring the docker network interfaces in the container.

Check_MK Werk 5953: lnx_thermal: Disabled in docker container contexts

by Lars Michelsen

ID: 5953 Title: lnx_thermal: 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 5952: docker_container_cpu: Check the CPU utilization of a docker container

by Lars Michelsen

ID: 5952 Title: docker_container_cpu: Check the CPU utilization of a docker container Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 This check reports the percentage CPU utilization of a docker container. Unlike the Linux CPU utilization check (kernel.util) it does only report user and system time. More detailed values, like iowait, are not available.
