Stress/Load Testing Dashboards?

Product: PowerShell Universal
Version: 2.4.0

Any recommendations on tools that can load test PSU dashboards? More focused on server performance testing than client-side.

Due to the WebSocket interaction, just aiming a traditional HTTP stress testing tool at one doesn’t really cut it and I don’t really want to adapt a WebSocket load testing tool to whatever PSU does, I basically just want to launch N number of user-agents instances and have them open a PSU dashboard target and then begin monitoring server performance impact but I’m only aware of SaaS providers providers that sort of solution.

What do people here do and use?
