Pyflame is a unique profiling tool that generates flame graphs for Python. Pyflame is the only Python profiler based on the Linux ptrace(2) system call. This allows it to take snapshots of the Python call stack without explicit instrumentation, meaning you can profile a program without modifying its source code! where's xur destiny 2 The tooltip function should implement two methods, .show (d) and .hide (), that will be called when the tooltip should be made visible or hidden respectively. The .show method takes a single argument, which is the flamegraph frame. The d3-flame-graph package includes a simple tooltip function, flamegraph.tooltip.defaultFlamegraphTooltip (). Then flame graph is occupied with a lot of [unknown] functions, even though some of unknowns have binary associated with them. Could you modify stackcollapse-perf.pl if it sees [unknown] but there's binary to show binary name, it could be like [/path/bin] for example. Or add option to do such replacements.
