Event parameter change

Hi!
Is there a way to find out about changing a parameter in a family?
I’m talking about running the script in the background immediately.
Suppose I changed the length parameter in the family and I would like to see this change.
Perhaps someone solved this problem?
I will be pre-emptive of any help.

PS
I know that you can get access to an event such as saving a file or adding a family to the project.

Is there any way to see the change of a parameter in a particular family?
Or is it impossible?
How much I understand it is necessary to look aside “events”?

Dynamo will detect that a parameter is changed and in automatic mode it will update the graph:

How does this code look like in C # or Py ?

Take a look at one of the event samples in the Revit SDK. It can be downloaded from here: https://www.autodesk.com/developer-network/platform-technologies/revit

Is this a Dynamo related question? If no, then you might be in a wrong place. If yes, then I think that @Einar_Raknes answered it pretty well. Dynamo already does the monitoring for you. Please accept a solution or provide more information.

Thanks to all who responded.
The problem is solved.
