Fyers Internal Logging Library

README

This module is installed via pip:

pip install otel-fyers-logger

Packages Required

• python-json-logger

Usage

Create a simple JSON Logger

import logging
from otel-fyers_logger import FyersLogger

logger = FyersLogger("fyers_logger", level=logging.DEBUG)

Set parameters for a request

import uuid

logger.set_fyId("ABC123")
logger.set_requestId(f"{uuid.uuid4()}")

Define logger with a custom handlers

from logging import FileHandler
from logging.handlers import TimedRotatingFileHandler
formatter = FyersLogger.get_json_formatter()

timed_rotating_handler = TimedRotatingFileHandler("fyers_logger_time_rotating.log", when="midnight", interval=1)
timed_rotating_handler.setFormatter(formatter)

simple_file_handler = FileHandler("fyers_logger.log")
simple_file_handler.setFormatter(formatter)

logger = FyersLogger("fyers_logger", handlers=[timed_rotating_handler, simple_file_handler], level=logging.DEBUG)

Add more handlers to the logger

new_file_handler = logging.FileHandler("fyers_logger_new_file.log")
new_file_handler.setFormatter(FyersLogger.get_json_formatter())
logger.add_handler(new_file_handler)

Log Data

logger.debug("This is a debug message", 1, 2,4, foo="bar", bar="baz")
logger.info("This is a info message", 1, 2,4, foo="bar", bar="baz", stacklevel=2)
logger.warning("This is a warning message", 1, 2,4, foo="bar", bar="baz")
logger.error("This is a error message", 1, 2,4, foo="bar", bar="baz")
logger.critical("This is a critical message", 1, 2,4, foo="bar", bar="baz")

try:
    raise Exception("DB connection error")
except Exception as e:
    logger.exception("getRRSpanFromDB", 1, 2,4, foo="bar", bar="baz")
