Collection Intervals
The ExtremeAnalytics engine collects and aggregates flow data for a period of
time called an interval. At the end of the interval, the engine writes the totals to
the Extreme Management Center database and a new interval begins, with new
totals collected starting at zero.
Some statistics are collected and written to the database on an hourly interval.
Other statistics are collected at a high-rate interval of every five minutes,
providing for a more detailed picture of how traffic changes over time.
This report shows application bandwidth over 24 hours based on an hourly
