Diagnosing an Instance

Scenario

If a fault or performance issue occurs, you can ask DCS to diagnose your instance to learn about the cause and impact of the issue and how to handle it.

Restrictions

DCS Redis 3.0 instances do not support diagnosis.

Procedure

1. Log in to the DCS console.
2. Click in the upper left corner of the console and select a region and a project.
3. In the navigation pane, choose Cache Manager.
4. Click the name of a DCS Redis instance.
5. Choose Analysis and Diagnosis > Instance Diagnosis.
6. Specify the tested object and time range, and click Start Diagnosis.
   • Tested Object: You can select a single node or all nodes. By default, all nodes are tested.
   • Range: You can specify up to 10 minutes before a point in time in the last 7 days.

     In the following figure, the data within 10 minutes before the specified time will be diagnosed.

     

     The system server time may be different from the current time. When the current time is selected, the actual diagnosis time range may be slightly shorter than the configured time range.

     Instance diagnosis may fail during specification modification.

7. After the diagnosis is complete, you can view the result in the Test History list. If the result is abnormal, click View Report for details. You can click Delete to delete a record.

   In the report, you can view the cause and impact of abnormal items and suggestions for handling them.
