# Monitor & Manage

You can monitor wait list size of your flow control key's from the console `FlowControl` tab. The console also allows you to pin, unpin, and reset rate for flow control keys directly.

Also you can get the same info using the REST API.

* [List All Flow Control Keys](/workflow/api-reference/flow-control/list-flow-control-keys).
* [Single Flow Control Key](/workflow/api-reference/flow-control/get-flow-control-key).
* [Global Parallelism](/workflow/api-reference/flow-control/get-global-parallelism).

## Manage

You can manage flow control keys by pausing/resuming delivery, pinning/unpinning configurations, and resetting rate counts.

These operations are available via the SDK, REST API, or directly from the **Flow Control** tab in the [Upstash Console](https://console.upstash.com).

Since Upstash Workflow uses QStash under the hood, flow control management is done through the QStash client. See the [QStash Flow Control Management API](/qstash/features/flowcontrol#management-api) for full details and code examples.
