Threshold Format¶ ↑

If argument is matched regex "/[0-9]+?/" or "nocheck", it's considerd as threshold.

Suffix character was consider as B=byte, K=KiloByte, M=Megabyte, G=GigaByte, T=TeraByte, P=PetaByte and %=Percent.

When string has no suffix character, longer than 3 will be treated as KiloByte, if not as percent.

This script alert when use% is over threshold of percentage or filesystem available size is under threshold of Byte and blocks.

ConfigFile Format¶ ↑

Same as command line arguments.

Especially, after "#" until end-of-line is considerd as comment.
