Determine data usage

I need to determine exactly how much data is moving during a perticular process.

If I want find out how much data moved from Server A through the UTM to Server B in a certain time frame, how do I get that data?

  • Hi Steve,

    I know this is a maverick answer, but just use tcpdump & wireshark.

    1) ssh-login into the UTM and execute (as root):
    tcpdump -pn -s 0 -w /tmp/sniff.pcap -i eth0 host A and host B
    (change eth0, A, B according your needs)

    2) Start your print job and if it's done, stop the tcpdump-job with CTRL-C. Then scp the /tmp/sniff.pcap file to your workstation and open it in wireshark

    3) In wireshark check the menu Statistics: Protocol Hierarchy... (Bytes for every protocol), Conversations (Bytes in every direction), Endpoints, IO Graphs (shows packets in a timegraph)
