Overview
The fault diagnosis tool helps you check the status of ECSs, RDS DB, DCS, DMS, and ELB instances, detect potential problems in a timely manner, and provide professional rectification suggestions and solutions for abnormal metrics. In this way, you can effectively manage resources and enjoy better cloud migration experience.

The diagnosis metrics vary depending on the cloud service resource type. For details about the diagnosis result, see the service ticket details.
Core Features
- Diversified diagnosis metrics: The diagnosis metrics cover commonly used inspection items of each cloud service instance, meeting routine diagnosis requirements.
- Professional repair suggestions: The diagnosis tool provides professional repair suggestions for abnormal items in the diagnosis result to improve your governance efficiency.
- One-click batch diagnosis: Cloud service instances of the same type can be selected in batches for quick diagnosis.
Typical Scenarios
Routine inspection: O&M personnel conduct routine inspections on resources and periodically execute batch diagnosis tasks to proactively identify risks in advance.
In the event of faults such as incidents or alarms, when the faulty instance is known, you can utilize the COC fault diagnostic tool for targeted in-depth diagnosis on the instance to identify and resolve faults at the instance level.
