Profiling

When profiling=True, SMonitor records durations per decorated frame and aggregates timing stats in report().

Decorator-based timing

import smonitor

smonitor.configure(profiling=True)

@smonitor.signal
def work():
    return 1

Manual spans

from smonitor.profiling import span

with span("data_loading", source="database"):
    pass

Sampling and buffer

smonitor.configure(
    profiling=True,
    profiling_sample_rate=0.1,
    profiling_buffer_size=200,
)

Export timeline

from smonitor.profiling import export_timeline

export_timeline("timeline.json", format="json")
