Are there application performance analysis tools (Windows + RPD + MS SQL)?

Question

User interface

Good afternoon!
Faced with the problem that we can not measure the quality of the application.
The application itself is running remotely, on a terminal server.
Users complain about periodic brakes in the operation of the interface, but
we cannot understand this problem in RDP or in the application itself.
Can someone tell me some tools for analyzing the performance of the interface?
I don't know, moving the mouse from corner to corner, handling the keyboard, rendering the screen, etc.
The problem can be both in the network, in the load of the terminal server, and in the load of the application, and it is a 3-link one. In moments when it slows down, in general, all indicators and graphs are normal. There are no visible splashes.
And we can monitor such cases only by calls from users.

Answer 1

administration, system monitor watch memory, disk

Answer 2

Unfortunately, this has no effect. How can monitoring understand lags in an application that is in an RDP session and understand why they are?
