# Monitor ingestion health

> Use sift_app to verify data flow, troubleshoot ingestion failures, and track pipeline performance.

After completing this workflow, you can confirm your data is arriving in Sift, identify records that failed to ingest, and track ingestion rates over time using **sift\_app**, a built-in system Asset.

## Before you begin

* You are familiar with how [Sift organizes data into Assets, Channels, and Runs](/documentation/get-started/data-model).

## How ingestion monitoring works

**sift\_app** is a built-in system Asset that provides real-time telemetry about your data pipeline's performance and stability. It surfaces internal metrics through the same infrastructure you use for your own data, allowing you to build dashboards and set up alerts for specific Channels using familiar Sift tools.

**sift\_app** is organized into four subsections, each representing a different layer of the ingestion journey:

* [**data\_import**](/documentation/reference/asset-settings#data_import): Metrics for data imported via file upload. Use this to confirm an import completed successfully or to understand why it failed.
* [**dlq\_ingestion**](/documentation/reference/asset-settings#dlq_ingestion): Metrics for records that failed to ingest. Use this if data is not appearing in Sift as expected.
* [**ingest\_grpc**](/documentation/reference/asset-settings#ingest_grpc): Metrics for data streamed through the gRPC APIs. Use this to confirm data is actively flowing into Sift.
* [**stream**](/documentation/reference/asset-settings#stream): Metrics for the Rust `sift-stream` client. Use this to monitor client-side ingestion behavior.

## Access sift\_app

1. Select **Assets** in the navigation.
2. In the **Asset name** search box, enter **sift\_app**.
3. In the **Assets** table, click **sift\_app**.
4. Click **Explore**.

## Monitor ingestion metrics

Once in Explore, the **sift\_app** subsections appear in the <Icon icon="wave-pulse" /> **Channels** tab.

1. Expand the subsection you want to monitor.
2. Click a Channel to plot it.
3. Review the plot to understand the current state of that part of your pipeline.

## Next steps

* To review and reingest data that failed, see [Recover failed ingestion data](/documentation/manage/identify-and-recover-failed-ingestion-data).
