This ZenPack is included with commercial versions of Zenoss and enterprise support for this ZenPack is provided to Zenoss customers with an active subscription.
The ZenPacks.zenoss.ZenHoltWinters ZenPack adds the ability to create threshold events when a device exceeds cyclical predicted values.
The Holt-Winters exponential smoothing algorithm is used for predictiond. For more information on RRD and Holt-Winters, refer to the rrdcreate command.
Warning: This ZenPack is not compatible with Zenoss 5 and later.
Warning: Zenoss platform relies on the existence of Holt-Winters RRAs within an RRD file. After adding Holt-Winters thresholds, the RRD files will need to be re-created so that the new configuration can occur. You will have to remove any existing RRD files so that new files can be created.
Removing RRD files will remove all historical information associated with these RRD files.
Note: Removing the RRD files does result in a loss of historical information.
