After Controller has collected new statistics, it compresses old data for each compression level by taking all intervals of the length specified by the
Interval configuration parameter, and replacing them with an average or sample value.
Controller begins compression at the point where statistics have a timestamp that is divisible by the value of the
Interval configuration parameter. An average value is used for compression of numerical statistics. For other statistics, Controller uses the most frequent value in the statistics for compression.
If you set
0, Controller removes statistics that are older than the value of
MinAge, rather than compressing them.
For clarity, HPE recommends that you specify the name of the level that deletes statistics as
ThrowAway, rather than
