Best way to monitor network traffic

asked 2013-06-20 17:23:03 -0600

anonymous user



I would like to use a deep packet inspection tool to monitor worker-instance traffic in an OpenStack-cloud, and was wondering what the best way to capture network traffic would be.

At the first look, I guess my two options are- 1. Setup a virtual switch (using OpenVSwitch or Nicara's NVP) and using it's SPAN port to get a copy of the network data. 2. Have software installed at the AMQP brokers to forward traffic (since all traffic concering worker instances passes through these brokers).

Can someone kindly validate this, or please suggest an alternate approach?

Thank you.

I can offer to try Anturis which is not bad at monitoring networks and other IT infrastructure.

With a dense traffic Wireshark might not handle the stream and will quickly get slow and eat up the memory. In that case, look for tcpdump which is much more efficient.

Hi Anonymous,

you may consider "WireShark" (link text) for your purposes.

B U T, this implies, that you have the permission to observe the network-traffic. Here, in Germany, this may become a little difficult, due to several restrictions by law. So be careful!
