Use the Diagnostic Reports feature in Database Autonomy Service (DAS) to generate a report for a specific time period when your ApsaraDB for MongoDB instance has performance issues or requires a routine health check. The report analyzes the instance's slow query log, tablespace, and performance trends to help you assess its health and quickly identify anomalies.
Prerequisites
The database instance must be an ApsaraDB for MongoDB instance.
Usage notes
You can run diagnostics only on secondary nodes.

Click Auto-generating Report Settings to configure scheduled triggers and automatically generate diagnostic reports.
NoteThe time range for a diagnosis cannot exceed 24 hours. Shorter time ranges provide more granular performance metrics.
