Checkmk Werk 15609: KUBE: Limit collection time for <tt>Persistent Volume Claims & Persistent Volumes</tt>

by External contributor

ID: 15609 Title: KUBE: Limit collection time for <tt>Persistent Volume Claims & Persistent Volumes</tt> Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0b7 This change affects those using the <tt>Kubernetes</tt> together with the feature <tt>Collect information about Persistent Volume Claims & Persistent Volumes</tt> (available in 2.2.0 and above). With this feature turned on, the Kubernetes agent will contact the kubelet on each node via a proxy provided by the Kubernetes API server. This means the data collection depends on the number of nodes and the latency of the Pod network. If this data collection takes too long, the Kubernetes agent may timeout. This in turn causes the previously collected API data to be discarded. With this Werk, the data collection time is limited to 30 seconds. The omission of the data causes the omission of metrics from the <tt>PVC</tt> service of a Pod. This is consistent with how missing data is handled, if the corresponding kubelet is down.

Checkmk Werk 15673: Logfile pattern analyzer: improve rule overview

by Lisa Pichler

ID: 15673 Title: Logfile pattern analyzer: improve rule overview Component: setup Level: 1 Class: New feature Version: 2.3.0b1 The "Logfile pattern analyzer" shows the configured "Logifle patterns" rules, but ordered them based on the rule number. This could make it difficult to spot for which folder the corresponding rule had been configured. The rules are now grouped and foldable by folder, similar to other rule overviews.

by External contributor

ID: 15468 Title: aws_lambda, aws_sns: Rename Lambda and SNS services Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0b7 The werk is incompatible for users that used AWS Lambda and AWS SNS services in versions from 2.2.0b1 to 2.2.0b6.

Checkmk Werk 15467: sap_hana: Enable clustering of active and passive nodes

by Sofia Colakovic

ID: 15467 Title: sap_hana: Enable clustering of active and passive nodes Component: agents Level: 1 Class: Bug fix Version: 2.3.0b1 Previously, we collected data only for databases in primary and logreplay_readaccess replication modes. For other replication modes only SAP HANA Status service was shown. In order to enable clustering of active and passive nodes, we now try to collect data for all replication modes and if the database cannot be accessed, the services of that host will go to STALE.
