Sysprof

Find and fix performance issues. Container Support Sysprof knows how to introspect rootless Podman and Flatpak containers. This means if you have the appropriate debug symbols installed in these containers, Sysprof will show you high-quality symbol names in the call stack. Callgraphs and Flame Graphs Sysprof can display your call stacks in the form of traditional call graphs or flame graphs. If your recording contains truncated stack traces, use the bottom-up feature to merge stack frames at the leaves. Platform Integration Many GNOME platform libraries include support for Sysprof, which can annotate your recordings with useful information. GLib can export main loop runtime information. GTK will give you frame clock timing, etc. The GNOME Shell compositor can also provide information about GPU hardware and frame composition! Libraries like Pango and GtkSourceView also provide Sysprof integration. Application Extensibility Use the Sysprof-capture-4.a static library in your own application to supplement recorded information with markers, counters, metadata, files, and more! D-Bus Monitoring Sysprof can record system and user session D-Bus. This allows you to view and search message content to understand what's happening. Use message timing information to understand what code was running when messages were sent! System Counters and Logs Use integrated counters for CPU, energy usage, graphics, network devices, and storage devices to track when specific issues occur. Systems with journald can automatically forward their logs to the recording. Scheduler Quanta Sysprof can record scheduler information for you, such as how long each process ran on each CPU. Use this to track latency and thread issues that hinder application performance.

Sysprof is a performance profiling tool designed to help developers find and fix performance issues in applications by providing detailed call stacks, system resources, and scheduler information to optimize performance.
