Checkmk Werk 13793: KUBE: Base Cluster aggregation on Node role

by Solomon Jacobs

ID: 13793 Title: KUBE: Base Cluster aggregation on Node role Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 You may find that some Nodes don't add resources to the overall workload your Cluster can handle. This werk introduces a new option, which allows you to remove Nodes from aggregations on the Cluster host based on their role. A node will be omitted, if any of the listed {role}s matches a label with name 'node-role.kubernetes.io/{role}'. This affects the following services: Memory resources, CPU resources, Pod resources. Only Services on the Cluster host are affected. By default, Nodes with role control-plane and infra are omitted.

Checkmk Werk 13838: TCP fetcher: don't connect if no data is needed

by Moritz Kiemer

ID: 13838 Title: TCP fetcher: don't connect if no data is needed Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 When fetching the data from a Checkmk agent (unix/windows), the fetcher would establish a connection before checking the cache file. If the cached data was still valid the connections has been closed. These "unused" connections could lead to unwanted agent executions or, in Checkmk 2.1, to irritating errors in the log of <tt>cmk-agent-ctl</tt> on the monitored host, such as "Request failed: tls handshake eof" or "Request failed: Connection reset by peer (os error 104)".

Checkmk Werk 13085: REST API: fix missing host/folder attributes

by Christoph Rauch

ID: 13085 Title: REST API: fix missing host/folder attributes Component: Core & setup Level: 1 Class: Bug fix Version: 2.2.0i1 This werk fixes the disappearing attributes (e.g. locked_by, locked_attributes). When editing hosts or folders through the REST API there could be a case, that certain fields were not in the list of editable attributes. If a user attempted to set this field (intrepreted as a "custom attribute") it would be treated as a string. This would then lead to subsequent errors. This werk also prevents internal attribute names to be used in "custom attributes". While the fix is in effect immediately for all newly done REST API calls, if a previous API call led to inconsistent data being stored in Checkmk, it may be neccessary to repeat the API call which led to the error. Ideally this would fix the error, though if this is not the case, contact us.

Checkmk Werk 13870: InfluxDB: Fix connection for remote sites

by Ronny Bruska

ID: 13870 Title: InfluxDB: Fix connection for remote sites Component: Linux Distributions Level: 1 Class: Bug fix Version: 2.2.0i1 If you configured an InfluxDB connection for a remote site, this connection was not used by the remote site. The configuration for InfluxDB connections is now stored in ~/etc/check_mk/conf.d/wato instead of ~/etc/check_mk/conf.d/. If you don't want to copy the file "influxdb_connections.mk" to the new location on the central site, you would need to configure your connections again.
