sysstra-logging

Shared structured (JSON-line) logging for Sysstra services. Stdlib-only — zero install dependencies — so lean scripts (data-collection streamers, cron jobs) can pick it up without pulling in the full sysstra SDK (pandas/numpy/numba/redis/pymongo).

from sysstra_logging import get_logger, bind, clear_context

logger = get_logger("trading-strategies", log_file="logs/syss_sha_eios.jsonl")

bind(mode="lt", request_id=request_id, strategy="syss_sha_eios")
logger.info("order placed", extra={"order_id": order_id})

Set LOG_FORMAT=text for a human-readable formatter during local dev / tail -f; the default is single-line JSON.

clear_context() must be called at the start of every unit of work (Celery task, HTTP request) that reuses a process/thread — otherwise bound fields from a previous task (most dangerously mode, paper vs. real-money) leak into the next one's log lines.

See sysstra_logging/logging_utils.py for the full API (bound(), get_context(), redirect_stdout_to(), ScrubFilter).
