atlas performanceAdvisor slowQueryLogs list
On this page
Return log lines for slow queries that the Performance Advisor and Query Profiler identified.
The Performance Advisor monitors queries that MongoDB considers slow and suggests new indexes to improve query performance. The threshold for slow queries varies based on the average time of operations on your cluster to provide recommendations pertinent to your workload.
If you don't set the duration option or the since option, this command returns data from the last 24 hours.
To use this command, you must authenticate with a user account or an API key that has the Project Data Access Read/Write role.
