atlas performanceAdvisor slowQueryLogs list
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.
