Unit Sizes

Some configuration directives in Fluent Bit refer to unit sizes such as when defining the size of a buffer or specific limits. Plugins like Tail Input, Forward Input, or generic properties like Mem_Buf_Limit use unit sizes.

Fluent Bit v0.11.10 standardized unit sizes across the core and plugins. The following table describes the options that can be used and what they mean:

Suffix	Description	Example
	When a suffix isn't specified, assume that the value given is a bytes representation.	Specifying a value of 32000 means 32000 bytes.
k, K, KB, kb	Kilobyte: a unit of memory equal to 1,000 bytes.	32k means 32000 bytes.
m, M, MB, mb	Megabyte: a unit of memory equal to 1,000,000 bytes.	1M means 1000000 bytes.
g, G, GB, gb	Gigabyte: a unit of memory equal to 1,000,000,000 bytes.	1G means 1000000000 bytes.
