Checkmk Werk 15140: fileinfo: Add the negative age tolerance parameter

by Sofia Colakovic

ID: 15140 Title: fileinfo: Add the negative age tolerance parameter Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 Previously, the state would be UNKNOWN if a file has a creation time from the future. A new parameter 'Negative age tolerance' has been added to 'Size and age of single files' and 'Size, age and count of file groups' rules. By setting the parameter, it's possible to ignore the negative age of the file.

Checkmk Werk 14573: Prometheus & Alertmanager: Deprecation of `IP Address` and `Host name` options

by Solomon Jacobs

ID: 14573 Title: Prometheus & Alertmanager: Deprecation of `IP Address` and `Host name` options Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The rules <tt>Prometheus</tt> and <tt>Alertmanager</tt> both allowed omitting the server address from the connection option by specifying <tt>IP Address</tt> or <tt>Host name</tt>. The corresponding agents would then generate URLs based on the host configuration. These options add complexity, are incompatible with proxy setups and less transparent than simply specifying the relevant URL. Therefore, these options will be removed in Checkmk 2.3.0. Affected users need to use the <tt>Custom URL</tt> option to specify the server address. For instance, assume your rule specifies <ul> <li><tt>IP Address</tt> </li> <li><tt>Port</tt>: <tt>9000</tt></li> <li><tt>Custom path prefix</tt>: <tt>my_prefix</tt></li> </ul> and your host has the address <tt>1.2.3.4</tt>. Then the new rule needs to specify C+: https://1.2.3.4:9000/my_prefix/api/v1/status/buildinfo C-:

Checkmk Werk 14572: Prometheus: Deprecation of `kube-state-metrics` scrape target

by Solomon Jacobs

ID: 14572 Title: Prometheus: Deprecation of `kube-state-metrics` scrape target Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The Prometheus agent provides the `kube-state-metrics` as a possible data source. This in turn would enable the following checks. <ul> <li>k8s_resources</li> <li>k8s_namespaces</li> <li>k8s_conditions</li> <li>k8s_pod_container</li> <li>k8s_service_info</li> <li>k8s_daemon_pods</li> </ul> However, these checks are no longer actively maintained, since they have been superseded by their counterparts in the Kubernetes agent. Moreover, the `kube-state-metrics` target <ul> <li>does not support new versions of kube-state-metrics (v2.0.0-alpha / 2020-09-16 or newer),</li> <li>does not provide the information required to fully support monitoring and</li> <li>is stricly inferior to monitoring via the Kubernetes agent.</li> </ul> For this reason, this option will be removed in Checkmk 2.3.0. If you are affected by this change, you need to setup your monitoring as per these instructions: https://docs.checkmk.com/latest/en/monitoring_kubernetes.html

Checkmk Werk 14768: mssql.vbs: some database specific sections contain data from a different database

by Lisa Pichler

ID: 14768 Title: mssql.vbs: some database specific sections contain data from a different database Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 If you require this fix, you must reinstall the agent plugin "mssql.vbs" on the relevant hosts. Please note that applying this fix could lead to vanished services. If this is the case, it makes sense to remove them from your monitoring, as these services belong to a different database and have been falsely created. You can find detailed error messages in the host's agent output. In some settings the user that is used to run queries against the various databases on a MSSQL server does not have access rights to query all databases. This could lead to data from a different database shown for any database that the user could not query. Known services affected by this error: LI: tablespaces LI: transactionlogs LI: datafiles LI: clusters The problem was that the error after attempting to switch to a different database was not captured, and it was assumed to be successful. Instead, the subsequent query was run against the database the user could last switch to. If you would like to give the user extended access rights to query all databases, please read the article at https://kb.checkmk.com/x/pAKqAg We have introduced a more consistent way to perform queries against the system and handle any errors.
