With the next release, the cdot performance getter will ignore temporary volumes. Temporary volumes are created in the background when moving volumes between aggregates, for instance. These volumes can lead to a UNKNOWN or an „out of bounds“ result for the performance checks and UsageTrend because these instances suddenly appear and disappear shortly thereafter. Therefore we think it’s best to exclude these temporary volumes from the monitoring process.
The pattern (regex) set with the --ignore switch is responsible for ignoring the volumes. All volumes that match this pattern are ignored by the getter and can therefore not be found in the store. This also applies for any other cdot performance objects that match this pattern!
The default setting for this switch is ^temp__, i.e. all volumes that start with temp followed by two underscores. In order to deactivate this filter set the --ignore switch to 0 (null).
