I am very new to SW and a bit overwhelmed. I previously used Cacti and was easily able to create a page that showed bandwidth usage for various interfaces. This would give me historical up to months (at a reduced granularity) and close to real time (5 minute intervals. I am looking to set up something like that now, as we have started using VOIP and I want to set up some other monitors and make sure that I don't negatively affect the bandwidth.
So far the only thing I find that is close, only goes back a week at the most and shows EVERY interface on a firewall. I can delete but it is tedious and I have to re-delete every time. I have many different areas that I want to monitor, so I may end up with several pages; one for internet, one for internal wan, one for voip, one for VPN and so on.
I don't mind reading and watching videos, but I feel that most of the time I am learning other things and I don't seem to find the video that shows what I want to do. Can someone point me to the right resources? And or tell me what terminology I need to be searching for?
