TCP destination plugin

TCP is a type of destination plugin that enables you to send your processed telemetry data to a remote TCP endpoint. With the TCP destination plugin, you can seamlessly integrate Calyptia Core with various TCP-based services, enabling you to transmit your data to remote systems or services over the network.

By using the TCP destination plugin, you can configure your Calyptia Core pipeline to send your data to a remote TCP endpoint, enabling you to integrate your telemetry data with other systems or services for various purposes. Whether you need to store, analyze, or use your data for other purposes, the TCP destination plugin provides a flexible and powerful solution for transmitting your telemetry data over the network.
