If you encounter problems when you use cloud resources, you can submit information to the automatic diagnostics system for troubleshooting.
Background information
The automatic diagnostics system provides the following features:
Simplified submission with near real-time feedback.
Intelligent processing that returns diagnostic results within seconds.
Extended support. The problems that cannot be handled by intelligent processing are immediately forwarded to Alibaba Cloud technical support personnel. This improves the overall efficiency of problem handling.
The following limits apply to the automatic diagnostics system:
You can access the automatic diagnostics system only in the Elastic Compute Service (ECS) console.
Each account can have up to 20 diagnostic records in the Pending state per region. You can submit new diagnostic requests in a region only when less than 20 diagnostic records are in the Pending state in the region.
You can view the diagnostic records of the last 30 days on the Troubleshooting page in the ECS console.
