Hello All, Up to today, I just tried to work with live profile and analyse, filter or list its content. Now I'd like to use the profile function but I don't know how to configure sources to create interesting graphs and profiles. Here is the situation. We have a big 6513 router connecting all internal Vlans. One of this router interfaces is plugged (across a firewall) to our front router (a cs7200 connected with a Gigabit interface on Renater). Both are netflow enabled and, at the present time, my main sources in the live profile. So here is some questions : - Have you an idea of the conf I should use (using samplicate and maybe nfsplit) to get representative graphs in nfsen ? - What the most used filters you use to manage your network ? - Do I have to create a source containing only the output traffic and an other input representative and how (nfsplit interfaces separation or other method) ? - How do you actually configure your routers, is only "ingress" traffic collected or both "ingress" and "outgress" ? - Which solution is the most effective ? What else do we have to know ? Thanks in advance for your answers. I think it could be usefull that the nfsen-masters explain how they work to the newbee like me. I'm a beginner in metrology science and dont know realy what are the important things I should manage and supervise. If an other newbee has other questions ideas, they are welcome :). Bye C=E9dric |
