No problem, that does answer my question and thanks, now I know so won't keep trying to find a way.
I mostly have linux servers with a handful of win machines.

 My apologies; I suppose I did not really answer your question.
 
 So, I don't know of a way to monitor only, without saving a capture --
 unless you are just going to watch via wireshark live.
 That is to say, fire up wireshark or tshark, and just watch the packets go.
 
 If you are on a *nix client, just use tcpdump.
 
 Dumpcap is quit a bit easier on resources, because it does not load display
 filters, so it can be used somewhat more discreetly.
 
 I think I understand what you are saying, but I don't know of any other way
 to view packets on the fly without saving them for later viewing.
 The "quick view of what's going on", would be either wireshark, tshark or
 tcpdump, live without saving the packets anywhere.
 
 Hope that helps.

 Can you just use dumpcap with a ring buffer?  Then stop the capture once
 the event you are looking for is seen:
