====== Checking DPI equipment configuration ======
<note>This use case is performed in [[dpi:qoe_analytics:qoe_gui:reports:online_reports_module]].</note>

Monitoring network status in real time is an ideal tool for debugging DPI configuration during initial setup or after making changes.

In particular, a network operator can set protocol priorities as follows:
  * YouTube – highest priority (cs_0),
  * Skype, Telegram – high priority (cs_1),
  * Torrent, P2P, Windows updates – low priority (cs_7).

After applying the corresponding settings in the GUI or configuration file, you can open the online report “Traffic by application protocols.” The graphs in real time will show the changes: YouTube will take all available bandwidth, while torrent traffic will be limited.

Detailed configuration of online reports is described [[dpi:qoe_analytics:qoe_gui:reports:online_reports_module#quick_start|here]]; for this use case, select the report “Traffic speed” → “Traffic by application protocols.”
