Logging

Structlog is used for structured JSON logging

Usage

import logging
from slat.log_util import LogUtil

log = LogUtil.init_logger(default_level='INFO',  correlation_id_key_val={'request_id': '999'})
log.info('is this JSON: {"answer": 42}')
log.error("the log message", some="value", extra_data=[1, 2, 3, "4"])
# only OUR logger will render as JSON
logging.getLogger("test").warning("hello")

output:

{"event": "is this JSON: {\"answer\": 42}", "level": "info", "logger": "slat.log_util", "request_id": "999", "timestamp": "2019-11-06T21:04:33.517295Z"}
{"event": "the log message", "extra_data": [1, 2, 3, "4"], "level": "error", "logger": "slat.log_util", "request_id": "999", "some": "value", "timestamp": "2019-11-06T21:04:33.517652Z"}
