Chronosphere Telemetry Pipeline uses *source plugins* to ingest telemetry data
into pipelines, either by receiving it (push) or collecting it (pull).
You can add and configure source plugins to connect your pipelines to a variety
of telemetry sources. Different source plugins support different data types,
including logs, metrics, and traces.
## Push-based and pull-based source plugins
Source plugins are either push-based or pull-based.
* **Push-based** source plugins passively listen for data emitted from a specified source.
* **Pull-based** source plugins actively fetch data from a specified source.
However, source plugins that output test data, like
[Datagen](/ingest/pipeline/plugins/source-plugins/datagen), are classified as pull-based
plugins even though they don't communicate with external sources.
