Script sharing for monitoring server hard disk usage implemented in Python

This script is mainly used for zabbix monitoring system hard disk only, suitable for Windows and Linux systems, return value of 0 is normal, there are several partitions of the hard disk remaining less than 10G or less than 10% is the alarm threshold (Windows C disk and Linux root partition except) :
