Determining cause of network traffic - wireshark
Hello. We have an application running on ServerA that is connecting to a SQL2005 database on ServerB. There is a constant (24x7x365) 30-50mb/s of network traffic generated between these two servers. Shutting down the application on ServerA causes ALL network traffic to cease. The vendor who supports the application on ServerA has NO idea what's going on and is blaming our SQL server (ServerB). Is anyone here knowledgeable with reading log files from Wireshark to determine what's going on and WHAT this traffic is/why? I have several packet captures available that shows the network traffic but my Wireshark skills aren't top notch. Curious if anyone here might care to take a peak for fun?

RE: Determining cause of network traffic - wireshark
I think I figured out what is causing this... the network trace is referring me to a log file generated by the application when i'm investigating.

RE: How much network traffic per app?
You think ntop would show me bandwidth usage on a lan or vpn?

As others have said, ntop does a good job. Another option I have used is mrtg. You could have mrtg monitor the bandwidth to the port where the server plugs into the switch, or monitor the server nic itself.

I hate to suggest this as it's so rudimentary, but isolate the server (or have a test server) and bring up the connection status and then benchmark the # of packets sent/received during a client/server session ... I like the MRTG option, you could monitor the router/switch port, and could also enable SNMP on the server and monitor there too... and several packet capture/sniffer type tools could also help to isolate your info, I think OmniPeek Personal would do that amongst others _ From: Benjamin Zachary - Lists [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 27, 2008 11:37 PM To: NT System Admin Issues Subject: How much network traffic per app?

Re: How much network traffic per app?
ntop is your friend. It can use bpf filters (same as Wireshark) to measure traffic and graph it between two (or more) machines, as opposed to all traffic on the wire that it sees. Placement is important - you'll need to put it on a monitor/span port, but it works really well for this purpose.

Re: How much network traffic per app?
mrtg is an option, but if you have other traffic on the wire, such as broadcast packets, etc., then it will artificially inflate the packet count. The bpf filters in ntop can be very specific, counting exactly what you want, including the correct port(s). It's the better tool for this pupose.

For example we wanted to track down a user that was pegging our T @ 97% utilization (he had 15 family guy downloads on morpheus at the same time) and TT did not tell us much.

Application software to monitor network traffic
Hi everyone, I am looking for a software that will monitor the network traffic on our LAN/WAN . Sometimes I find the network is very sluggish and at other times, it is normal, I want to pin down the problem. I also expect the software to be able to identify which workstation is transferring big files, such a ppt file etc. Thanks for your info.

RE: Application software to monitor network traffic
Two programs you can check are Sniffer Pro and Network Monitor. I am not sure if they can tell you what file, but they can identify workstations via IP address.
