About Query

• You can query the real-time data of the last 24 hours.
• You can query data in a time span of up to 24 hours.

Procedure

1. Log in to the SparkRTC console.
2. In the navigation pane on the left, choose Analytics (Beta) > Diagnostics.
3. On the displayed page, enter or select an app ID to view all call exception data of the target app.

   The diagnosis data chart displays the following information: user data by exception type, exception causes, and details about all users with abnormal call experience.

   • Overview

     Displays user data by exception type, including Users with slow loading, Users with audio freeze, and Users with video freeze.

     • Users with audio freeze: indicates the number of users who take a long time to join a room
     • Users with audio freeze: indicates the number of users who have audio freezes during calls
     • Users with video freeze: indicates the number of users who have video freezes during calls
   • Exception Causes

     Displays details about the exception causes in a specified period, including exception types and the proportion and number of affected users by exception. For details about the exception causes, see Table 1.

     Note: In the statistical chart, if the number of data items is less than or equal to 5, all exception causes and their proportions are displayed in descending order. If the number of data items is greater than 5, the fifth one and all data items following it are classified as Other and displayed as the fifth item in descending order.

     • Type: indicates the type of a call experience exception, including slow room loading, video freeze, and audio freeze
     • Cause: indicates the cause of a call experience exception. For details, see Table 1.
     • Proportion: indicates the proportion of the number of users affected by an exception
     • Users: indicates the number of users affected by an exception
