[//]: # (werk v2) # kube_persistent_volume_claim: resolve KeyError crash when Volume parameters are configured key | value ---------- | --- date | 2024-04-03T10:30:30+00:00 version | 2.4.0b1 class | fix edition | cre component | checks level | 1 compatible | yes Before this update, configuring 'Volume parameters' in the PVC check plugin led to a crash. This issue arose because the plugin was not designed to process trend size-related levels, which, however, were anticipated by the general filesystem function handler shared among filesystem-related check plugins. To resolve this, the general function has been modified to bypass trend computation when a trend rule is not set, a scenario always applicable to the PVC check plugin.
