Visualize network connections and devices

Hello, can any of you guys recommend a good software to visualize all network connections between network devices?

We have SolarWinds right now but I don't think it's doing a good job. It's kind of OK to monitor individual devices, but when you try to see the big picture - it's a mess, especially if I'm trying to see 50 VPN tunnels to 50 different locations. As far as I can tell it's almost impossible unless you do some voodoo custom stuff. As far as devices it mostly Cisco Switches and ASAs, couple Uniquity routers, a lot of HP blades, a few Nexus 5Ks.

Thanks,
