Need suggestions on Next generation monitoring network monitoring tools

We have moved from MPLS to SD-WAN network.

We are starting to have several issue with Solarwinds and Solarwinds support team has not been helpful either.

Also, we have gone to through 2 or 3 Solarwinds upgrade with software and hardware as well so far!!!

So I am looking to see if we can find another network monitoring tools that we can replace Solarwinds with it.

Please give me your feedback/suggestion on some good network monitoring tools.

Please send me the name of the network monitoring tools that you recommend so I will add it to my list to get review before we make final decision.

The new network monitoring tools needs to meet the following requirements:

Network monitoring tools need to be able to work/monitor the following network hardware:

1- SD-WAN connection using Silver-Peak device

2- LAN switch using Meraki switch

3- Wireless using Meraki access point

4- UPS using APC

5- Open-Gear and Trip-Lite

Network Size:

1- Around 475 branch offices

2- Two Data Centers

Monitoring requirements:

1- Monitor and send alerts for all network equipment for up and down status.

2- Be able to create monthly Capacity Management for all of our WAN circuits.

3- Managing the WAN with correct bandwidth size for each interface in the monitoring tools

4- Be able to create monthly Availability Management for all of our WAN circuits

for Monday through Friday between 7 AM and 7 PM ONLY.

5- Measuring VOICE quality at each of our offices and be able to send alerts pro-actively for any Voice issue.

6- Be able to find the slow response application from user point of view and find any network issue pro-actively.

Note: Network monitoring tools needs to be able to deliver the above basic functionality out of the box without writing any custom API.
