Transform OTTL

Overview

The Transform OTTL processor applies OTTL statements to log records. It allows conditional transformations using one or more statement blocks and a configurable error handling mode.

Supported types: Logs

Configuration

Parameter	Type	Default	Required	Description
error_mode	string	ignore	Yes	Controls how the processor handles errors while evaluating OTTL statements. Supported Values : ignore propagate

• ignore Continues processing even when a statement fails.
• propagate Propagates the error and stops processing for the current record.

Log Statements

Each item in log_statements defines a block of OTTL statements that are evaluated for logs.

Parameter	Type	Default	Required	Description
conditions	array[string]	none	No	Optional OTTL conditions that must be true before the statements are applied.
statements	array[string]	none	Yes	OTTL statements to execute when the conditions match.

Note: Conditions are optional. If no conditions are provided, the statements are always executed.
