Sysprof is a sampling profiler that uses a kernel module to generate stacktraces which are then interpreted by the userspace program “sysprof”.
This is free and open source software.
Key Features
- Detailed, accurate, and fast profiling of the entire Linux system, including the kernel and all userspace applications.
- No recompiling necessary.
- Load and Save> profiles.
- Fast, no-nonsense graphical user interface.
- Command line tool included.
- Container support – Sysprof knows how to introspect into both rootless Podman and Flatpak containers. That means if you have the appropriate debug symbols installed in those containers then Sysprof will show you high-quality symbol names in call stacks.
- Callgraphs & Flamegraphs – Sysprof can show your call stacks in the form of a traditional callgraph or flamegraph. If your recording contains truncated stack traces then use the bottom-up feature to merge stack frames from the leaves.
