Guider: Performance Tracing Features for Linux
summary
Guider is a pure‑Python runtime tracer and profiler for Linux that attaches to running tasks and can also execute binaries to start tracing, requires no rebuild or external binaries, and fits in about 1 MB of storage. It injects trap breakpoints via ptrace to capture native function call/return events, supports Python call tracing and signal/IO capture, and produces SVG timelines, scheduling views and per‑file/device IO summaries (example: ~57% of reads are 4K). Commands include live argument/memory reads and remote python callbacks.
