Datadog Processing Language (DPL), or Vector Remap Language (VRL), is an expression-oriented, domain specific language designed for transforming logs. It features a simple syntax and built-in functions tailored to observability use cases.

Datadog Processing Language is supported in the remap transform.

Remap transforms act on a single event and can be used to transform them or specify conditions for routing and filtering. You can use DPL in the following ways:

• Manipulate arrays, strings, and other data types.
• Encode and decode values using Codec.
• Encrypt and decrypt values.
• Coerce one datatype to another datatype (for example, from an integer to a string).
• Convert syslog values to read-able values.
• Enrich values by using enrichment tables.
• Manipulate IP values.
• Parse values with custom rules (for example, grok, regex, and so on) and out-of-the-box functions (for example, syslog, apache, VPC flow logs, and so on).
• Manipulate event metadata and paths.
