Updates

Depending the type of Anomaly Detection, data is recalculated on an hourly or daily basis.

Hourly anomalies are calculated on the first Data Collection run that occurs 30 minutes after the hour. Any newly available data is applied to the calculations up through the preceding complete hour. For example, if the calculation is done at 10:40 am, it includes any new data that is timestamped before 10:00 am. In this example, data with a timestamp between 10:00 am and 10:40 am is not applied to the calculations during the current run.

Daily anomalies are calculated at 4:30 am each morning. Any newly available data is applied to the calculations up through the preceding complete day. For example, if the calculation is done at 4:30am on April 26, it includes any new data that is timestamped before 12:00 am April 26. In this example, data with a timestamp between 12:00 am and 4:30 am April 26 is not applied to the calculations during the current run. You can change the time when calculations are done for daily anomaly detections.

In some cases, an Anomaly Detection update gathers new data that had been spooled during an earlier period. If spooled data is processed, then when the Anomaly Detection calculation run next runs, the spooled data is included as part of the Anomaly Detection data set. All relevant calculations are done to include the newly captured data in the Anomaly Detection values.

In environments where data is spooling, Anomaly Detections can be retroactively recalculated when the spooled data is later processed.
