Monitor task performance

Procedure

1. Log on to the DTS console.

2. In the upper-left corner, select the region where your instance is located.

3. In the left-side navigation pane, click Data Synchronization or Data Migration depending on the task type.

   Note

   This topic uses a data synchronization task as an example.

4. On the Data Synchronization page, click the ID of the target task.

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

6. View performance details for full or incremental data synchronization:

   • View the link status and performance of full data synchronization.

     1. Click the Performance of Full Data Synchronization tab at the top of the page.

     2. View the full data synchronization topology and trend charts for metrics over a custom time range.

        Feature	Description
        Topology of full data synchronization	The topology of full data synchronization shows the read/write and network status for the link from the source database to DTS and from DTS to the destination database. The link from the source database to DTS BPS: The amount of data that DTS reads from the source database per second, in MB/s. RPS: The number of rows that DTS reads from the source database per second. Network Latency: Network latency between DTS and the source database. The link from DTS to the destination database BPS: The amount of data that DTS writes to the destination database per second, in MB/s. RPS: The number of rows that DTS writes to the destination database per second. Network Latency: Network latency between DTS and the destination database.
        Performance of full data synchronization	View metrics for full data synchronization, including traffic, RPS for source and destination instances, read/write response times, and network latency. Note Hover over the icon next to a performance metric to view its detailed description and reference values.

   • View the performance of incremental data synchronization.

     1. Click the Performance of Incremental Data Synchronization tab at the top of the page.

     2. Below the Topology of Incremental Data Synchronization area, click the Performance of Incremental Data Synchronization tab.

     3. View the topology of incremental data synchronization and trend charts for metrics over a custom time range.

        Feature	Description
        Topology of incremental data synchronization	The incremental data synchronization topology shows data transmission and network latency between the modules in the link. The modules include the source database, data collection module, data cache module, data writing module, and destination database. BPS: The amount of data transmitted per second between modules in the link, in MB/s. RPS: The number of rows transmitted per second between modules in the link. Network Latency: Network latency between modules in the link.
        Performance of incremental data synchronization	View performance metrics across different stages of incremental data synchronization, such as data collection and the data cache module. Key metrics include synchronization traffic, performance, and latency.

FAQ

• Where is the Quick Diagnostics feature?

  The Quick Diagnostics feature has been moved from the Performance Monitoring page to the Task Management page. On the Task Management page, click the target task. Then, at the bottom of the page in the Quick Diagnostics area, click the Health Details tab and then the Quick Diagnostics button.

• How do I adjust the data transfer rate for a full or incremental task after the instance is started?
