Notes

• Data in Real-Time Data is for data analysis and quality issue query only. Services are charged based on bills.
• The latest data will be displayed at most 5 minutes after it is generated.

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) > Real-Time Data.
3. On the displayed page, enter or select an app ID to view the real-time monitoring data of the target app.
4. You can view the following real-time monitoring data of a call project:
   • Dashboard: displays the quantity of online users/rooms, quality, and exceptions
   • Scale: displays the online user-related data within a specified time range
   • Experience: displays the experience data within a specified time range
   • Network: displays the network data within a specified time range

Dashboard

Click the Dashboard tab to check the overall project status, including the number of online rooms/users, success rate of joining a room in 5 seconds, audio/ video smoothness, and call exceptions.

• Online Rooms: A room is online after the first user joins the room and before the last user leaves it.
• Online Users: indicates the number of online users. If a user joins n rooms using the same username, the number is n (n > 1).
• Room Loaded in 5s: Number of users who join a room in 5 seconds / Number of users who attempt to join a room
• Smooth Audio: (Total audio duration – Audio freeze duration) / Total audio duration. The audio freeze duration is counted once it reaches 200 ms.
• Smooth Video: (Total video duration – Video freeze duration) / Total video duration. The video freeze duration is counted once it reaches 600 ms.
• The number of online users in each region is displayed in the map of China.
• Alarms: This area is displayed only when an exception occurs. A maximum of 6 alarms can be displayed. Table 1 lists the abnormal events and their respective detection thresholds.

  Downlink video freeze	5%
  Downlink audio freeze	3%

Scale

Click the Scale tab to check the number of online rooms and online users and how these two indicators change within a specified time range. You can also view the number of online users in different regions, as well as the network types, OSs, and SDK versions of online users.

In the upper part of the page, you can adjust the desired time range and specify whether to update chart data in real time.

• Overview: displays the number of online rooms and online users and how these two indicators change within a specified time range
  • Online rooms: A room is online after the first user joins the room and before the last user leaves it.
  • Online users: indicates the number of online users. If a user joins n rooms using the same username, the number is n (n > 1).

• Distribution: Regions are sorted by the number of online users in descending order. The number of online users in each region and its proportion to the total number of online users are displayed.
• Network Types: Network types are sorted by the number of online users in descending order. The number of online users of each network type and its proportion to the total number of online users are displayed.

  Note: In the statistical chart, if the number of data items is less than or equal to 5, all network types 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.

• OSs: Operating systems are sorted by the number of online users in descending order. The number of online users of each OS and its proportion to the total number of online users are displayed.

  Note: In the statistical chart, if the number of data items is less than or equal to 5, all OSs 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.

• SDK Versions: SDK versions are sorted by the number of online users in descending order. The number of online users of each SDK version and its proportion to the total number of online users are displayed.

  Note: In the statistical chart, if the number of data items is less than or equal to 5, all SDK versions 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.

Experience

Click the Experience tab to check the success rate of joining a room and that of joining a room in 5 seconds, audio and video freeze rates, and successful stream push/pull. You can also view the number of online users by network type, OS, and SDK version, as well as the experience data (real-time or within a specified time range).

Network

Click the Network tab to view the high-quality audio and video upload rates of the client and those of each region.
