Netflow gives you all the flows so it's just about organizing it. Personally I use scrutinizer, the free version only keeps 24 hours of data but it's great for real time.

Hello<br />
I am looking to see what can I use other than netflow to monitor bandwidth. In other words, How can I tell whether traffic is generated internally or is it an ISP issue?<br />
I can implement the netflow top-talkers but I am not exactly sure what is a lot and what is normal usage. How can I differentiate that? What if I do “show interface fa0/0 for ex. What am I looking at there and what numbers should be treated as normal? And what numbers are beyond normal usage?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
