Add labels
Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Serverless interfaces and procedures might differ from classic Elastic Stack deployments. The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats. Availability This functionality is generally available and ready for production usage. Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

The add_labels processors adds a set of key-value pairs to an event. The processor flattens nested configuration objects like arrays or dictionaries into a fully qualified name by merging nested names with a dot (.). Array entries create numeric names starting with 0. Labels are always stored under the Elastic Common Schema compliant labels sub-dictionary.
This configuration:
- add_labels:
labels:
number: 1
with.dots: test
nested:
with.dots: nested
array:
- do
- re
- with.field: mi
Adds these fields to every event:
{
"labels": {
"number": 1,
"with.dots": "test",
"nested.with.dots": "nested",
"array.0": "do",
"array.1": "re",
"array.2.with.field": "mi"
}
}
Elastic Agent processors execute before ingest pipelines, which means that they process the raw event data rather than the final event sent to Elasticsearch. For related limitations, refer to What are some limitations of using processors?
