All data can be exported for the given criteria, or data for the last specified number of days. The export facility is run from the Server. Explanation of how the summaries are generated is detailed in the following examples. 1 Raw data is collected every 15 minutes on attribute upstreamPower for 10000 cable modems. Daily and monthly summaries are required for upstreamPower using an average summarizing rule.
Summarization occurs when any data of a higher granularity is about to be deleted.
In this example, deleting raw data only generates the daily summaries, not the monthly summaries. Monthly summaries are generated when daily summaries are about to be deleted. Data is not purged until summaries which depend on that data can be calculated. Example 2 Raw data is collected every 15 minutes on attribute upstreamPower for 10000 cable modems. A SixMonthly summary is required for upstreamPower using an average summarizing rule.
