Unit Sizes

Last updated 4 years ago

Was this helpful?

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 , or in generic properties like .

Starting from 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
