# Debug (in a stream)

Once a stream is uponed in the stream designer the debugger can be opened/activated via the "Debug" icon in the upper bar.

This open a debug overlay that shows the realtime output of streams (during execution), limited to the currently open one. The size of the debug overlay can be extended to full screen by clicking on the arrow on the right side.

Additionally it is possible to access a global view of the [Stream Debugger](/helmut4-releases/v4.7.1/helmut4-components/streamdesigner/stream-debugger.md) to monitor and control all processes according to stream. For that the "Debug Streams" button which can be found in the Streams tab of FX, IO, CO and HK should be clicked. This leads to the action that the stream debugger will be opened.&#x20;
