====== Building reports in the QoE statistics section ======
<note important>This scenario describes how to generate reports for a short period.\\ If you need to build a report for several days or longer, it is recommended to use the "My reports" section of the operator GUI. [[dpi:qoe_analytics:qoe_gui:offline_analytics:large_report_manager|Instruction]].</note>

Statistics from the DPI are accumulated in the QoE cluster. To build a report, go to the QoE Analytics section of the operator interface — it provides access to QoE.\\
The following sections are available:  
  * NetFlow  
  * Raw full NetFlow  
  * ClickStream  
  * Raw ClickStream  
  * DNS flow  
  * Raw DNS flow  
<note important>GTP flow reports are intended for mobile operators, and NAT flow reports are for NAT translations on DPI.\\ **GTP flow and NAT flow reports are not used.**</note>

===== Building a report =====
  - Select the section and report **(1)**. You can refer to the table in [[dpi:qoe_analytics:qoe_gui:reports:paramdescript|]] from the VAS Experts documentation for assistance;  
  - Select the period for which the data will be displayed in the report **(2)**;  
  - Set report filters **(5)**. More about filters can be found in [[dpi:qoe_analytics:qoe_gui:reports:qoe_filters|]] in the VAS Experts documentation.  

The data in the report can be displayed as a table or a chart.  
For reports that support charts, you can choose the chart type **(11)**: spline area, area, stacked area, line, or stacked histogram.

The generated report can be exported as:
  * A table — in Excel, TabSeparated, CSV, PDF, PNG **(9)**. You can specify the number of rows per page **(10)**, and this number will be reflected in the exported report;  
  * A chart — in PNG or PDF formats **(12)**.

<note>
If necessary, you can specify additional settings for report generation:
  * Select from which device the data will be displayed **(3)**;  
  * Set the maximum report execution time **(4)** — this defines how long the report can take to load. If the report is not completed within this time, the loading will stop.
