Trending techniques

There are two trending techniques: real-time trending and average trending.

Logging of all values, in a sliding window of maximum 1000 hours.

In most cases, real-time trending will be set to 24 or 48 hours.

Note

It is possible to set a default sliding window size for real-time trending on a particular DMA. See Setting the default sliding window size for real-time trending.

Logging of average values only, usually across longer time spans than those used for real-time trending.

  • Last 48 hours, with 5-minute averages.

  • Last week, with 5-minute averages (max. 2016 data points).

  • Last month, with 5-minute averages (max. about 8640 data points).

  • Last year, with 1-hour averages (max. about 8760 data points).

Note

In case of average trending, the DMS not only stores the average value for a particular time slot, but also the minimum and maximum value detected in that same time slot.
