Performance Monitoring Network

Q&A: What is the best software for network performance monitoring?

Problem by Jon O: What is the greatest computer software for network efficiency checking?
What software package is regarded as the ideal for complete network efficiency checking. I am in search of a computer software that will keep track of our switches, routers, firewalls, and the total overall performance of our network. This is a network working Win 03 as the OS, and has around sixty-eighty servers. Any ideas? What are the pros and cons of this kind of computer software?

Very best solution:
