Thank you in advance for any help.
I run a network consisting of a Cisco 800 series router and about 75 workstations/servers. I'm gotten some complaints about network/internet performance which led me to research solutions available for monitoring bandwidth.
My research seemed to indicate that enabling netflow would be the best way to monitor internet usage. Would this be correct?
I went through the process of:
1. Enabling Netflow and streaming the data.
- interface Ethernet0
- ip route-cache flow
- ip flow-export 192.x.x.x 9996 version 5
2. I installed a program called ManageEngine NetFlow Analyzer. (Just picked it from a google search.
The streaming appears to be working because I'm getting some data... but the numbers don't seem entirely accurate? I tested by downloading files from various test stations and the totals being reported back are off. I've also found that the outbound traffic is not displayed (tested this with another analyzing application).
Any help would be appreciated. Any steps I may have missed when enabling netflow? Any suggestions for a better application to use? Better ways to monitor bandwidth usage?
