I suspect there's advantages and disadvantages to each... -Jon Hartman -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Masood Ahmad Shah Sent: Friday, March 26, 2004 12:51 PM To: Zeeshan Ahmed; Victor Souza Menezes; [EMAIL PROTECTED] Subject: [mrtg] Re: monitoring bandwidth per protocol yeah Zeeshan is right you can use ip nbar. if your router did not support ip nbar then run cache flow on required interface and get statistics via netflow or you can write your own expect script to get statistics from router. I'm sure you can find tool or script via search on net that can be use to get cache flow statistics. Rule of thumb if you have data u can generate graph :) Best Regds, Masood Ahmad Shah Nexlinx http://nexlinx.net.pk ----- Original Message ----- From: "Zeeshan Ahmed" <[EMAIL PROTECTED]> To: "Victor Souza Menezes" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Thursday, March 25, 2004 11:21 AM Subject: [mrtg] Re: monitoring bandwidth per protocol > i do it in the way that i have enabled the NBR o my cisco router that > differentiate the traffic per protocol then i get stats throygh mrtg > from NBR. > > Regards > Zeeshan Ahmed > ----- Original Message ----- > From: "Victor Souza Menezes" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Thursday, March 25, 2004 2:31 AM > Subject: [mrtg] monitoring bandwidth per protocol > > > > Hi all, > > > > I'm running mrtg-2.10.13 on a Red Hat 9 system to monitor a router > > of my > network > > and it works fine. > > > > If i want to monitor, for example, the traffic on my network per protocol > , i > > mean, TCP, X11, HTTP, ARP, POP, etc, what should i do??.
