Hi thailamng-9584,
I’m afraid that no such tool for Skype for Business on-premises.
Skype for Business server 2019 has the following service management tools:
- Call Quality Dashboard
- KHI Resources
- Statistics Manager for Skype for Business Server 2015
- Manage Skype for Business Server 2019 using SCOM Management pack
- Skype for Business Server Capacity Planning Calculator
We recommend you that please give a feedback to https://www.skypefeedback.com/forums/299913-generally-available/suggestions/41190922--microsoft-skype-for-business-network-assessment-t.
Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
