Hey all, I have the pleasure to finally announce the availability of hotspot v1.0.0. Hotspot is a GUI for Linux perf. Right now, it's a drop-in replacement for (parts of) `perf report`. It aims to be easier to use, but comes with powerful features to analyze the profiler data:
- summary view - bottom-up, top-down and caller/callee aggregations - tooltips, searching, sorting etc. as expected from an interactive GUI - integrated flamegraph (probably the most important feature) - ability to show multiple event metrics side-by-side The full release announcement contains pretty screenshots: https://www.kdab.com/hotspot-gui-linux-perf-profiler/ You can download the release tarball from GitHub: https://github.com/KDAB/hotspot/releases/tag/v1.0.0 Thanks, hope you like it. If so, please consider contributing: Patches: https://github.com/KDAB/hotspot/pulls Bug Reports: https://github.com/KDAB/hotspot/issues PS: If you dislike GUIs and want to see me instead improve `perf report` itself, don't worry! I've done that in the past and will continue doing so in the future ;-) PPS: If you wonder why I'm developing this out-of-tree: I simply believe that this is the easiest approach for me to get things done. Trying to refactor the perf internals to make it work for me use-case is a daunting task. PPPS: If you wonder what that means for `perf report --gtk`, then I can't tell you. It never worked for me and I believe it's rather unmaintained and unfunctional anyways. I'm a C++/Qt/KDE guy, so I used the technologies I'm familiar with.
