I look after a network of about 100 PC workstations, 60+ SUN/Microsoft servers. At the access layer I use 2960G's and 3560G's. My routing (inter-VLAN) is handled by the 3560G's (and it works quite well). At the core of my network I have a stack of 3750's. Beyond that I make use of Fortinet hardware for firewalls, etc.
For my monitoring I use the freeware version of OP Manager. It works well, gives me graphs in real-time, and basic reports.
My company is giving serious thought to relocating our datacenter from our building to a co-located facility.
I really want to get a better understanding of the flow of traffic at the core of my network. Netflow seemed like the perfect choice but it is not supported on any of the switches I use. The data I get from OP Manager really isn't enough. I don't have the time to evaluate lots of different products, and need something that I can get up and running quickly so I can begin to gather the information that is required to enable us to make an informed decision over the connections we will need from our building to the co-located site. Please do not worry about the detail of this. I know there is far more to this. At this stage I am just looking for a product that can detail the flow (volume) of data within the switch.
Hope this makes sense.
