# TCP destination plugin

export const entity_0 = "TCP destination plugin"

export const plugin_0 = "TCP destination plugin"

The TCP [destination plugin](/ingest/pipeline/plugins/destination-plugins)
(name: `tcp`) lets you configure your telemetry pipeline to send your data to
a remote TCP endpoint, letting you integrate your telemetry data with other
systems or services for various purposes.

## Supported telemetry types

The {plugin_0} for Chronosphere Telemetry Pipeline supports these telemetry types:

|                    Logs                    |             Metrics             |              Traces             |
| :----------------------------------------: | :-----------------------------: | :-----------------------------: |
| <Icon icon="circle-check" color="green" /> | <Icon icon="ban" color="red" /> | <Icon icon="ban" color="red" /> |

## Configuration parameters

Use the parameters in this section to configure the {entity_0}. The
Telemetry Pipeline web interface uses the items in the **Name** column to
describe these parameters. [Pipeline configuration files](/ingest/pipeline/v2/configure/config-files)
use the items in the **Key** column as YAML keys.
