What is Trace Viewer and when is it used?

Trace Viewer is a tool for visualizing and analyzing traces of program or system execution. It allows viewing detailed information about call sequences, events, delays, and interactions between components.

When to use Trace Viewer:

• For performance diagnostics and identifying bottlenecks.
• For analyzing distributed systems and microservices, where understanding the call chain is important.
• When debugging complex processes to see the order and timing of operations.
• In QA and automated testing to analyze application behavior under load.

Example: Chrome DevTools has a built-in Trace Viewer that helps developers analyze webpage performance by showing timelines, events, and resource loading.

Thus, Trace Viewer helps visualize and understand complex execution processes, facilitating problem detection and optimization.
