See configuration for more info.

Type	Syntax	Default	Example
array	literal		["my-source-or-transform-id","prefix-*"]

type(required)

The component type. This is a required field for all components and tells Vector which component to use.

Type	Syntax	Default	Example
string	literal		["metric_to_log"]

Advanced Options

host_tag(optional)

Tag key that identifies the source host.

Type	Syntax	Default	Example
string	literal	hostname	["host","hostname"]

timezone(optional)

The name of the time zone to apply to timestamp conversions that do not contain an explicit time zone. This overrides the global timezone option. The time zone name may be any name in the TZ database, or local to indicate system local time.

How it Works

State

This component is stateless, meaning its behavior is consistent across each input.
