This topic describes how to view the traffic monitoring data of applications.

Prerequisites

The deep packet inspection (DPI)-based monitoring feature of Smart Access Gateway (SAG) is enabled. For more information, see Manage DPI.

View traffic distribution of applications

  1. Log on to the SAG console.
  2. In the top navigation bar, select the region where the SAG instance is deployed.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the instance details page, click the Monitoring tab.
  5. On the Monitoring tab, click DPI Statistics on Applications.
  6. On the DPI Statistics on Applications tab, you can view the following information:
    • DPI Statistics by Application Group: displays the traffic percentage of each application group for the current SAG instance by default.
    • DPI Statistics by Application: displays the traffic percentage of each application by default.
    • DPI Statistics by Request Source: displays the traffic percentage of each application by request source by default.

View traffic distribution of specific applications

On the DPI Statistics on Applications tab, you can set the following conditions to filter traffic monitoring data. For example, you can view the traffic percentages of applications during a specified time period or traffic percentages of specified applications.
  • topN: queries the traffic information about the top 10, top 50, top 100, or top 500 applications, application groups, or application request sources that have the highest percentages of traffic.
  • Time: Click Select in the upper-right corner of the tab to select a time period for querying traffic distribution of applications.

    You can set the time period in the following formats:

    • Relative: queries traffic distribution of applications from the current time to a specified time in the past.

      For example, you can select 5 Minutes and the current time is 14:33:38 (UTC+8) on November 26, 2020. In this case, the traffic distribution from 14:28:38 (UTC+8) on November 26, 2020 to 14:33:38 (UTC+8) on November 26, 2020 is queried.

    • Rounded to Hour: queries traffic distribution of applications from the beginning of the current hour to a specified time in the past.

      For example, you can select 1 Hour and the current time is 14:33:38 (UTC+8) on November 26, 2020. In this case, the traffic distribution from 13:00:00 (UTC+8) on November 26, 2020 to 14:00:00 (UTC+8) on November 26, 2020 is queried.

    • Custom: queries traffic distribution of applications during a custom time period.
  • Specified Applications: queries traffic distribution of applications in specified application groups or of specified applications.

    For example, the following figure shows the traffic percentage of each application for a specified SAG instance. The information is displayed on the DPI Statistics by Application Group tab. If you click the green area in the ring diagram, you are redirected to the DPI Statistics on Applications tab. This tab displays the traffic distribution of each application in the General internet group.
