Analyze Slow Queries

Atlas provides several tools to help analyze slow queries being executed on your clusters.

Performance Advisor

The Performance Advisor monitors queries that MongoDB considers slow and suggests new indexes to improve query performance.

Real-Time Performance Panel

The RTPP identifies relevant database operations, evaluates query execution times, and shows the ratio of documents scanned to documents returned during query execution.

Query Profiler

The Query Profiler displays slow-running operations and their key performance statistics.
