查看磁盘容量息的key值：vfs.fs.size[/,pfree]
vfs.fs.size[/,pfree]：取/领域的剩余空间率。p是percentage，
vfs.fs.size[/,free]：取/领域的剩余空间。对应的单位就是B（这里的意思是Byte）
vfs.fs.size[/,pused]：取/领域的使用空间率。
vfs.fs.size[/,used]：取/领域的使用空间。
如果要创建触发器表达式可以使用{ZABBIX-CC:vfs.fs.size[/,pfree].last(0)}<20

# explain
This PEP proposes extended usages of the * iterable unpacking operator and ** dictionary unpacking operators to allow unpacking in more positions, an arbitrary number of times, and in additional circumstances. Specifically, in function calls, in comprehensions and generator expressions, and in displays.
