# Forwarding to External Collectors

If you already collect flow data into a collector, you can optionally add an external flow collector to the ThousandEyes flow process. This allows you to send your flows to your existing (or another) flow collector for ingestion into additional network flow analysis tools while simultaneously ingesting them into ThousandEyes.

For information about collecting flows into ThousandEyes, see [Configuring Forwarders](https://docs.thousandeyes.com/product-documentation/traffic-insights/traffic-insights-configuration-guide/configuring-forwarders).
