The one-click diagnosis feature helps you troubleshoot system performance issues that involve multiple kernel subsystems. These issues often manifest as a single abnormal metric, making it difficult to pinpoint the root cause by investigating a single subsystem alone. The feature analyzes monitoring logs and other data to select the appropriate diagnostic tools. It then correlates data from these tools to perform root cause analysis and provide an end-to-end solution.
Limitations
The SysOM component must be version 3.7.0 or later.
Region limitations
This feature is currently available only in the Chinese mainland and China (Hong Kong) regions.

-
Enter the instance ID of the instance to diagnose and click Perform Diagnosis.
A one-click diagnosis runs multiple checks and can take 5 to 10 minutes. You can view the results later in the diagnosis records.
Diagnostic report
-
Basic Information
The Basic Information section contains details about the diagnosis, including the instance ID, resource ID, diagnostic item, diagnostic report ID, and start time.
-
Diagnosis conclusion
If any anomalies are detected on the instance, the details are listed in this section.
-
Diagnostic suggestions
If anomalies are found on the instance, this section provides suggestions for further troubleshooting.
A one-click diagnostic report has three sections: Basic Information, which includes the instance ID, resource ID, diagnostic report ID, diagnostic item, and start time; Diagnosis conclusion, which lists detected anomalies such as excessive file cache usage, frequent page swapping, abnormal disk I/O traffic, high disk write latency, network packet loss, and high system load; and Diagnostic suggestions, which recommends optimizations and provides access to tools like Panoramic Memory Analysis, One-click I/O Diagnosis, and Packet Loss Diagnosis.
