The fieldname that you are counting should be part of the filter string. So either you can count tcp.len or you can change the filter to "tcp and tcp.len>0 and tcp.dstport==4176"

 

Hope this helps,

Cheers,

Ronnie,

 

The filter is tcp.len>0 and tcp.dstport==4176 and the COUNT(*) variable is "tcp".

 

The graph is a flat line at 0.

 

If I apply the filter as a display filter, I get lots of packets displayed, so I know the count isn't really zero.

 

What did I miss?

 

Chuck

If you want to count how many packets there were  just specify "tcp" (or any field really would work) and it will count how many frames there are containing tcp.

If you want to count how many bytes were carried inside tcp use SUM(tcp.len) since this will add toghether all tcp.len fields it finds.

In an Advanced IO Graph, I have set the filter to tcp.len>0 to give me packets that have data. Now, I want to display how many in each time period made it through that filter. I presume I use a COUNT(*) graph, but what variable do I use?
