What is the best software for monitor network?

Solarwainds Network Monitoring

Wireshark program

it depends upon whre you are confgiuraing.

For industrial use it is my assumption that

observium(Network monitoring server ) is the best solution. the point is that you  have to make it professional version not community version.

Hope it helps.
