====== Regregation of outdated aggregated fullflow logs ======
{{indexmenu_n>4}}


===== Appointment =====

Aggregation of the fullflow log occurs by grouping data by time and other key fields. By default, the aggregation period is 15 minutes. It can be changed in the settings.

But, sometimes you need to change the aggregation method depending on how outdated the data is. For example, the first week we need an aggregation period of 5 minutes to get more accurate information in time, when and what requests the subscriber made, for example. Further, the data becomes outdated and such accuracy is no longer needed, while accurate data takes up more disk space.

A mechanism has been implemented by which aggregations can be divided into 3 periods. By default it is like this:

  - The first week we store data with a grouping of 15 minutes
  - The first month, starting from the second week, we store data with a grouping of 30 minutes
  - Starting from the second month, we store data with a grouping of 1 hour

The functionality is implemented in dpiui2 2.31.2 and QoE Stor 1.19.1

Step 2.

===== Logs =====

Tasks to transform the aggregation period depending on the interval are performed by the GUI in the background.

The progress of these tasks can be seen in the QoE Analytics \ Administrator section
