ATS doesn't keep track of the bytes exchanged at the TCP layer - you may need
to dig into some of the available network tools (e.g tcpview, netstat etc) on
how they collect this information and write a plugin that can do that on ATS.
Below is a link with some useful/relevant tips:

Subject: how to get the more accurate bytes of each client's usage
Hi:
I am using following set of api long clientReqHdrBytes =
TSHttpTxnClientReqHdrBytesGet(txnp); long clientReqBdyBytes =
TSHttpTxnClientReqBodyBytesGet(txnp); long clientRspHdrBytes =
TSHttpTxnClientRespHdrBytesGet(txnp); long clientRspBdyBytes =
TSHttpTxnClientRespBodyBytesGet(txnp);to get the usage byte numbers of all
client related request and response.but obviously I have not counted all the
TCP bytes using these API.Is there a way I can get the usage including the TCP
layer.I have used wireshark to track the real bytes transferred.it looks the 66
bytes of TCP layer (IPV4) is not counted in both request and response.also all
the other 66 bytes TCP ACK, SYN, FIN are all not counted.I would like to have
a way to count all the bytes communicated with the client.
Shall I use the code in plugin/tcpinfo?Thanks.Cheng Yi
