Guider: A New Performance Monitoring Daemon
summary
Guider is an open source Python daemon that runs on Linux/Android (limited macOS/Windows) and continuously monitors CPU, memory, block IO, network, IPC, IRQ and scheduling, using ptrace-based breakpoints for native traces and a Python tracer for interpreter stacks. It auto-generates timestamped text reports and SVG visualizations, triggers user-defined commands on threshold events, has a ~1 MB footprint and costs about 1–5% CPU while recording detailed per-process stats, syscalls, backtraces and long-term graphs.
