# Indexer Cluster (Discovery) You can launch the proxy to forward data to one or more indexer instances directly by using master/manager indexer discovery. This will auto-discover indexers that are managed by the indexer cluster manager periodically. The discovered indexers are put in a load-balanced group for forwarding. The proxy configuration wizard will ask you to provide the configuration parameters below * Index to send data to * Cluster manager API endpoint for indexer discovery - e.g. ** * Workers - To scale up forwarding you can launch with multiple workers * Version - The version of the forwarder to use. Apica can release new versions of the forwarder over time with newer capabilities. * Latest version of plugin is **logiqai/hauler-splstos:v1.5** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
