Description of problem:
Run the below python code

from libnmstate import netapplier
from libnmstate import netinfo
from libnmstate.schema import Interface
import logging
import sys
import yaml

def logger_level(logger, verbose=False, debug=False):
log_level = logging.DEBUG
if debug:
log_level = logging.DEBUG
elif verbose:
log_level = logging.INFO
logger.setLevel(log_level)

def configure_logger(log_file=False, verbose=False, debug=False):
LOG_FORMAT = ('%(asctime)s.%(msecs)03d %(levelname)s '
'%(name)s.%(funcName)s %(message)s')
DATE_FORMAT = '%Y-%m-%d %H:%M:%S'
logger = logging.getLogger("os_net_config")
logger.handlers.clear()
logger_level(logger, verbose, debug)
logger.propagate = True
formatter = logging.Formatter(fmt=LOG_FORMAT, datefmt=DATE_FORMAT)
if log_file:
file_handler = logging.handlers.RotatingFileHandler(
_LOG_FILE, maxBytes=10485760, backupCount=7
)
file_handler.setFormatter(formatter)
logger.addHandler(file_handler)
stream_handler = logging.StreamHandler(sys.stdout)
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)
return logger

logger = configure_logger()

logger.debug("--------PRE_NETINFO LOG----------------")

ifaces = netinfo.show_running_config()[Interface.KEY]
ifaces_dmp = yaml.dump(ifaces, default_flow_style = False,
allow_unicode = True, encoding = None)
logger.debug("------POST_NETINFO_LOG-----------------")
logger.debug("Running info: \n %s" % ifaces_dmp)

Its found that after invoking netinfo.show_running_config(), the logs are duplicated.

Version-Release number of selected component (if applicable):
nmstatectl 2.2.6
