Filters in reports allow the user to filter data by certain criteria. This is convenient for quick search of necessary information in large volumes of data.

Report filtering takes place in the QoE sections of the analytics: Netflow, Raw full netflow, Clickstream, Raw clickstream.
Before applying filters to reports, you must select data by a specific time interval using the "Period" field:

There are two options for selecting a period:

1. Custom range — arbitrary Start and End of period, set manually;
2. Quick ranges — ready-made date and time intervals, selectable from the list given.

Used when you want to track the activity of a specific subscriber, a pool of subscribers or a list of subscribers.
1. Select the "Subscriber" filter;
2. Customize the filter by one of three options:

Single subscriber
Subscriber pool
Subscriber list

3. Enable the filter by checking the checkbox to the left of the filter to be configured;
4. Click "Apply".

It is used if you need to find subscribers who have visited a specific resource or list of resources.
