VisuaLeaf Query Profiler - Analyze and optimize MongoDB queries

Slow Query Analysis

Identify and analyze slow queries with detailed execution metrics. View queries grouped by collection with COLLSCAN warnings, execution plans, scan metrics, and duration highlighting. Search, filter by time range, operation type, and collection to pinpoint performance bottlenecks. Export results to CSV or JSON for further analysis.

Index Recommendations

Get intelligent index recommendations based on profiled queries. Automatically detects missing indexes causing collection scans, calculates performance impact with priority scoring, and provides ready-to-use index creation commands. View benefits, query patterns, and ESR (Equality, Sort, Range) ordered index suggestions for optimal performance.

Visual Performance Insights

Monitor query performance with interactive scatter plots showing operation duration over time. Filter by time range, operation type, minimum duration, and collection. View operations summary grouped by namespace and operation type with detailed metrics including mean time, total time, count, and quick access to query details.

Visual Query Builder

Visual Query Builder

Identify slow queries in the Profiler, then optimize them using the Visual Query Builder. See which queries need indexes, then rebuild them visually with proper field selection and filtering. Close the loop between profiling and optimization.

Visual Schema

Visual Schema

Use the Query Profiler to find performance bottlenecks, then view your schema to understand why. See which fields lack indexes, identify missing relationships, and plan schema improvements based on actual query patterns from the profiler.
