Check_MK Werk 7415: Extensions for the Kubernetes special agent and checks

by Tom Baerwinkel

ID: 7415 Title: Extensions for the Kubernetes special agent and checks Component: Checks & agents Level: 2 Class: New feature Version: 1.6.0i1 This werk introduces multiple extensions for the Kubernetes special agent, new checks and inventory plugins: - The special agent now provides piggyback data for Pods, Deployments and Services. - The piggyback output is optional and can be configured via the rule for the special agent. - The special agent now outputs the Kubernetes labels for piggyback hosts. They are shown in the HW/SW invenotry and on the host detail page of the hosts. You can add the labels to other views and use the labels to filter your views. The labels will be used in more upcoming features in the future. - The check k8s_resouces is now used for Pods as well. - The new summary check k8s_pod_container for the Pods of a container is added. - The new inventory plugin k8s_pod_info shows Pod information in the HW/SW inventory. - The new check k8s_replicas monitors the replica sets of Deployments. - The new inventory plugin k8s_service_info shows information about Kubernetes Services. - The new inventory plugin k8s_selector shows the selectors of Kubernetes Services. - The new check k8s_service_port monitors the Ports defined for Kubernetes Services.

Check_MK Werk 7342: Removed legacy_checks configuration variable

by Lars Michelsen

ID: 7342 Title: Removed legacy_checks configuration variable Component: Core & setup Level: 1 Class: Bug fix Version: 1.6.0i1 The long time deprecated configuration variable <tt>legacy_checks</tt> has been removed now. It was replaced by the <tt>custom_checks</tt> option which is working a bit different. In case you configured Check_MK only via WATO you will not be affected by this issue, since legacy_checks could only be configured directly in the configuration files. In case you need to migrate your configuration, you could move the configuration to the WATO ruleset "Classical Active and Passive Monitoring Checks". If you need to migrate the configuration by hand have a look at the CMC migration documentation (https://mathias-kettner.com/cms_cmc_migration.html#legacy_checks) which describes the steps.

Check_MK Werk 7304: Solaris uptime consistent across global & local zones

by Óscar Nájera

ID: 7304 Title: Solaris uptime consistent across global & local zones Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Solaris uptime check was not working correctly since not all versions of Solaris and within global and local zones return consistent information. This fix reverts Werk 4623, which fixed the problem for some setups but broke it for others. Currently Solaris agent will deliver more system information about uptime. The check performs a cross validation of data, if values are consistent uptime is returned. For inconsistent values, check goes into UNKNOWN state and user is required to fix/patch their Solaris system. Additional information of conflicting data is given to the user. An agent update is needed.
