    Data Transmission Service:Monitor task performance

    Last Updated:Apr 22, 2024

    Data Transmission Service (DTS) provides the performance monitoring feature that allows you to view the topologies and performance data of DTS tasks. You can view the status and performance metrics of a DTS task on the details page of the DTS task. This helps you manage the DTS task.

    Procedure

    1. Log on to the DTS console.

    2. In the upper-left corner of the page, select the region in which your DTS instance resides.

    3. In the left-side navigation pane, click Data Synchronization or Data Migration based on the type of the DTS task that you want to monitor.

      Note

      In this example, a data synchronization task is used.

    4. On the Data Synchronization page, find the instance that you want to manage and click its ID to go to the instance details page.

    5. In the left-side navigation pane, click Performance Monitoring.

    6. Perform the following operations based on the synchronization type:

      • View the topology and performance of full data synchronization.

        1. Click the Performance of Full Data Synchronization tab.

        2. You can view the topology of full data synchronization. You can also select a time range to view the trend charts of performance metrics for full data synchronization within the specified time range.

          Section

          Description

          Topology of Full Data Synchronization

          In this section, you can view the read/write performance and network information about the connections between DTS and the source and destination databases. The following parameters are displayed:

          • Connection between DTS and the source database

            • BPS: the amount of data that DTS reads from the source database per second. Unit: MB/s.

            • RPS: the number of records that DTS reads from the source database per second.

            • Network Latency: the network latency between DTS and the source database.

          • Connection between DTS and the destination database

            • BPS: the amount of data that DTS writes to the destination database per second. Unit: MB/s.

            • RPS: the number of records that DTS writes to the destination database per second.

            • Network Latency: the network latency between DTS and the destination database.

          Performance of Full Data Synchronization

          In this section, you can view the information such as the bandwidth of full data synchronization, records per second (RPS) of the source and destination databases, read/write response time, and network latency.

          Note

          To view the description of a specific performance metric, move the pointer over the图标 icon in the upper-right corner of the trend chart of the performance metric.

      • View the topology and performance of incremental data synchronization.

        1. Click the Performance of Incremental Data Synchronization tab.

        2. On this tab, you can view the Topology of Incremental Data Synchronization and Performance of Incremental Data Synchronization sections.

        3. View the topology of incremental data synchronization. You can also select a tome range to view the trend charts of performance metrics for incremental data synchronization within the specified time range.

          Section

          Description

          Topology of Incremental Data Synchronization

          In this section, you can view the data transmission status and network latency between multiple modules The modules include the source database, data collection module, data cache module, data writing module, and destination database. The following parameters are displayed:

          • BPS: the amount of data that is transmitted between DTS modules per second. Unit: MB/s.

          • RPS: the number of records that are transmitted between DTS modules per second.

          • Network Latency: the network latency between DTS modules.

          Performance of Incremental Data Synchronization

          In this section, you can view the incremental data collection performance, log cache module performance, and incremental data synchronization performance. For example, you can view the performance information such as the bandwidth, RPS, and synchronization latency.

    FAQ

    • How do I use the quick diagnostics feature?

      The Quick Diagnostics section is moved from the Performance Monitoring page to the Task Management page. To use the quick diagnostics feature, go to the Task Management page. Find the module that you want to manage and click its name. On the Health Details tab of the Quick Diagnostics section that is displayed in the lower part of the page, click Quick Diagnostics.

    • How do I enable throttling for a full or incremental data synchronization or migration task after the task starts?

      For more information, see Enable throttling for data migration.
