Problem in generating logger file to a specific path

I am trying to generate a log file to a specific folder and path in greengrass v2. however the log file is created at the current directory.

The current directory at which the logger file is generated is

/sim/things/t1_gateway_iotgateway_1234/greengrass/packages/artifacts-unarchived/com.data.iot.RulesEngineCore/2.3.1-pp.38/package

Could you please help me where am I missing?

The following is my program.

import logging
from datetime import datetime
import os, sys
from logging.handlers import RotatingFileHandler

def getStandardStdOutHandler():

    formatter = logging.Formatter(
            fmt="[%(asctime)s][%(levelname)-7s][%(name)s] %(message)s (%(threadName)s[% (thread)d]:%(module)s:%(funcName)s:%(lineno)d)"
        )

     filename = datetime.now().strftime("rule_engine_%Y_%m_%d_%H_%M.log")
     path = "/sim/things/t1_gateway_iotgateway_1234/greengrass/logs/"

    _handler = RotatingFileHandler(path + filename, maxBytes=1000000, backupCount=5)
    _handler.setLevel(logging.DEBUG)
   _handler.setFormatter(formatter)
   return _handler


def getLogger(name: str):
    logger = logging.getLogger(name)

    logger.addHandler(getStandardStdOutHandler())

    return logger
