    Smart Access Gateway:Application traffic monitoring

    Last Updated:Jun 20, 2026

    This topic explains how to view application-based traffic monitoring data.

    Prerequisites

    You have enabled the application identification feature for your Smart Access Gateway instance. For more information, see Manage the application identification DPI feature.

    Application traffic distribution

    1. Log on to the SAG console.

    2. In the top navigation bar, select the target region.

    3. On the Smart Access Gateway page, click the ID of the target Smart Access Gateway 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: By default, the system displays each application group's share of the instance's total traffic.

      • DPI Statistics on Applications: By default, the system displays each application's share of the instance's total traffic.

      • DPI Statistics by Request Source: By default, the system displays each request source's share of the instance's total traffic.

    Traffic distribution for specific applications

    On the DPI Statistics on Applications tab, you can use the following filters to view traffic distribution for a specific time range or for specific applications.

    • topN: Use this filter to view traffic information for the top 10, 50, 100, or 500 application groups, applications, or request sources, ranked by traffic share.

    • Time: Click the time selector in the upper-right corner of the tab to select the desired time range.

      The following time range options are available:

      • Relative: Displays traffic data for a period just before the current time.

        For example, if you select 5 minutes and the current time is 14:33:38 on November 26, 2020, the system displays application traffic distribution information from 14:28:38 to 14:33:38 on the same day.

      • rounded to hour: Displays traffic data for the last full hour.

        For example, if you select 1 hour and the current time is 14:33:38 on November 26, 2020, the system displays application traffic distribution information from 13:00:00 to 14:00:00 on the same day.

      • Custom: Displays traffic data for a custom time range.

    • Specify application: Specify an application group to view the traffic distribution of each application within that group, or specify an application to view the traffic distribution of its request sources.

      For example, the DPI Statistics by Application Group tab shows the traffic share of each application group by default. If you click a specific group, such as General internet, the SAG console automatically switches to the DPI Statistics on Applications tab and displays the traffic distribution of individual applications within that group.
