Where did you find this "Data rate" if it is not a field? Columns are generally fields shown for all packets (unless a packet doesn't contain that specific field). answered 13 Sep '13, 02:52  Jasper ♦♦ |
Find the field in the proto tree, then right click it and select "Apply as Column". answered 13 Sep '13, 02:54  grahamb ♦ |
There is no general data rate field (at least I don't know one), with some minor exceptions, where a protocol provides some kind of negotiated data rate. See
So, if you are looking for one of those exceptions, please add details about the protocol you are interested in. If you looking for a general data rate fields, i.e. number of bytes/second: Fields are properties of frames/packets. A data rate would be an information about the amount of data (bytes/frames) transmitted in a defined time interval. It would not make sense to add that information to a single packet as a field. So, if you need information about the data rate over time in a conversation, I suggest to use IO graphs.
That will show you the packets/bytes per tick (seconds) over the lifetime of the conversation.
== UPDATE == According to the screenshot, I'd say that the "Data Rate" is actually the field radiotap.datarate So, here we go:
Click Add and then change the fields type to Custom. Insert the following into 'Field name:': radiotap.datarate. Finally rename the Column from 'New Column' to 'Data Rate'. Hint: That field will only be there if a Radiotap header is available (wifi traffic in certain capture environments)!! BTW: If there is a radiotap header, you can just open it and click on "Data Rate:". Then right click and choose 'Apply as column'. See also:
