Systems with many devices or with devices performing frequent acquisitions can require significant disk space to store data. InsightCM provides features for automatically discarding data events after configurable conditions are met. This automatic process, called aging, conserves disk space while maintaining a desirable collection of data.
InsightCM applies the periodic aging strategy to individual data events that are not part of a stream. The streaming aging strategy is used to discard entire streams. InsightCM does not retain partial streams.
A calendar-based strategy enables you to determine which and how much data to discard. This strategy follows a time-based schedule to discard data events after a configurable number of days. You can configure the strategy to discard all data sets except those collected at a specific time. For example, you can retain some data to trend over an extended period of time by configuring a calendar-based strategy that deletes all periodic data events except those collected at 12:00pm after two days elapse.
You can identify data that InsightCM exempts from aging on the Trend viewer. The Trend viewer shows data points from times that are exempt from aging rules. For example, if InsightCM is configured to delete all periodic data three days after collecting it, but the Trend viewer displays a value that is five days old, that data point is exempt from aging.
