Guider: Lightweight Real-Time Performance & Fault Monitoring Framework for Embedded...
summary
Guider is a self-contained monitoring toolkit for embedded Linux that continuously runs from boot, captures ftrace/atrace/ptrace/kprobe/uprobe/DWARF-backed samples, and automatically reacts to anomalies using JSON threshold rules. It exposes a simple TCP/UDS remote API for CI or fleet control, stores structured captures (traces, flame graphs, peak analysis, resource summaries), and ships 183 built-in commands for profiling, breakpoint counting, per-connection network/storage stats, and bulk server-side report aggregation with minimal runtime dependencies.
