Werk 15609 was adapted. The following is the new Werk, a diff is shown at the end of the
message.
Title: KUBE: Limit collection time for <tt>Persistent Volume Claims & Persistent
Volumes</tt>
Class: fix
Compatible: compat
Component: checks
Date: 1682683781
Edition: cre
Knowledge: doc
Level: 1
Version: 2.3.0b1
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.
