I use snmpc, manage engine netflow (also csmars sometimes) to monitor the network wan links. But i need something that can do automated reports on monthly utilisation for about 20 router wan links.
Has anyone tried anything thats really good. I heard Cacti might be an option?
I need this to be automated so i can just hit a button and get the reports nice and easy after i have it all setup and syslog traffic going back to the server.
