Siren Platform User Guide

Federate includes a license manager service and a set of rest commands to register, verify and delete a Siren’s license. By default, the Siren Community license is included.

Without a valid license, Federate will log a message to notify that the current license is invalid whenever a search request is executed.

Put License

The Put License API allows to upload a license to the cluster:

PUT /_siren/license

Let’s assume you have a Siren license named license.sig. You can upload and register this license in Elasticsearch using the command:

$ curl -XPUT -H 'Content-Type: application/json' -T license.sig 'http://localhost:9200/_siren/license'
---
acknowledged: true

Get License

The Get License API allows to retrieve and validate the license:

GET /_siren/license

The response includes the content of the license as well as a summary of the license validation. If the validity check fails, a list of invalid parameters with a cause is provided:
