logging TypeError: not all arguments converted during string formatting

[Daiyue Weng]

Hi, I am trying to record memory and CPU usages and load a logger from an
external config file (logging.conf),

[loggers]
keys=root,hardware_log

[handlers]
keys=consoleHandler,hardwareFileHandler

[formatters]
keys=hardwareFormatter

[logger_root]
level=DEBUG
handlers=consoleHandler

[logger_hardware_log]
level=DEBUG
handlers=hardwareFileHandler
qualname=hardware_log
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=DEBUG
formatter=hardwareFormatter
args=(sys.stdout,)

[handler_hardwareFileHandler]
class=handlers.RotatingFileHandler
maxBytes=51200
level=DEBUG
formatter=hardwareFormatter
args=("log/hardware.log",)

[formatter_hardwareFormatter]
format=pathname~%(pathname)s||timestamp~%(asctime)s||level~%(levelname)s||name~%(name)s||function_name~%(funcName)s||line_no~%(lineno)s||debug_CPU~%(message)s||debug_Mem~%(message)s
datefmt=%m/%d/%Y %H:%M:%S
class=logging.Formatter


import logging

import psutil

logging.config.fileConfig('logging.conf')

hardware_log = logging.getLogger(HARDWARELOGNAME)

free_mem_gb_pre = psutil.virtual_memory().available / 1000000000.
cpu_util_pct_pre = psutil.cpu_percent()

hardware_log.info(cpu_util_pct_pre, free_mem_gb_pre)


I got the following errors,
