# Prometheus scrape source plugin

export const entity_0 = "Prometheus scrape source plugin"

export const plugin_0 = "Prometheus scrape source plugin"

You can use the Prometheus scrape [source plugin](/ingest/pipeline/plugins/source-plugins)
(name: `prometheus_scrape`) to ingest data from your Prometheus instances and
into a telemetry pipeline.

This is a [pull-based](/ingest/pipeline/plugins/source-plugins#push-based-and-pull-based-source-plugins) source plugin.

## Supported telemetry types

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

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