Trace Breakdown

No Transaction Left Untraced!

Scout automatically collects and analyzes transactions across your web endpoints and background jobs. Visual indicators highlight performance hotspots, helping you quickly pinpoint issues down to the specific line of code, author, commit date, and deploy time. You can also optimize your traces with custom context – like user IDs, subscription tiers, or business metrics – for deeper insights and additional filtering options!

Summary view

Aggregates all identical method calls and ranks by total cost – perfect for quickly identifying your most expensive operations.

Timeline view

Shows the chronological execution order of every call, letting you see exactly how your code flows during a request – great for identifying issues like N+1 queries or blocking operations that delay other processes.

Slowest requests

Identify poorly performing requests to focus your optimization efforts where it matters most.

User analysis

Track and analyze application performance across different users to understand their experience.

Problem endpoints

Spot endpoints generating excessive slow requests and impacting overall performance.

Custom filters

Filter transactions using any custom dimension to drill down into specific scenarios.

Visual insights

Explore and analyze trace metrics through interactive histograms that reveal patterns.

Live updates

Watch filtered trace lists update in real-time as you explore different performance dimensions.

GitHub Integration

Code Backtraces with GitHub Integration

If you've enabled GitHub integration, you can see the line of code, associated SQL or HTTP endpoint, and the author, commit date, and deployment time for the relevant slow code. If GitHub integration isn't enabled, you'll still see a detailed backtrace.

SQL Insights

Monitor Database Performance with Deep SQL Insights

Stop wasting time hunting down database problems! Scout automatically sanitizes and captures SQL queries, letting you track database performance without compromising security. Spot N+1 problems instantly with inline annotations, and click the "SQL" button next to any call to view complete query details. For optimal performance, Scout limits query statement collection to 16k characters.
