class DatadogAPIClient::V1::LogsArithmeticProcessor

Use the Arithmetic Processor to add a new attribute (without spaces or special characters in the new attribute name) to a log with the result of the provided formula. This enables you to remap different time attributes with different units into a single attribute, or to compute operations on attributes within the same log. The formula can use parentheses and the basic arithmetic operators `-`, `+`, `*`, `/`. By default, the calculation is skipped if an attribute is missing. Select “Replace missing attribute by 0” to automatically populate missing attribute values with 0 to ensure that the calculation is done. An attribute is missing if it is not found in the log attributes, or if it cannot be converted to a number. Notes: - The operator `-` needs to be space split in the formula as it can also be contained in attribute names. - If the target attribute already exists, it is overwritten by the result of the formula. - Results are rounded up to the 9th decimal. For example, if the result of the formula is `0.1234567891`, the actual value stored for the attribute is `0.123456789`. - If you need to scale a unit of measure, see [Scale Filter](docs.datadoghq.com/logs/processing/parsing/?tab=filter#matcher-and-filter).

Attributes

expression[RW]

Arithmetic operation between one or more log attributes.

is_enabled[RW]

Whether or not the processor is enabled.

If `true`, it replaces all missing attributes of expression by `0`, `false` skip the operation if an attribute is missing.

name[RW]

Name of the processor.

target[RW]

Name of the attribute that contains the result of the arithmetic operation.

type[RW]
