Unit Sizes

Certain configuration directives in Fluent Bit refer to unit sizes such as when defining the size of a buffer or specific limits, we can find these in plugins like Tail Input, Forward Input or in generic properties like Mem_Buf_Limit.
Starting from Fluent Bit v0.11.10, all unit sizes have been standardized 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 is not specified, it's assumed 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
