automate network performance data collection

My goal

Use pre-existing capture files from Wireshark to extract data into a file that can be parsed by Excel or other style process.
Data collection format would be as follows if I was using the online option of IO graph

• Filter for Graph #1 ip.dst==10.0.2.15
• Filter for Graph #2 ip.dst==10.0.2.15

Special settings: Tick interval = 1 or 10 seconds Y axes is measured in Bytes / Ticks view as time of day Select graph 1 and graph 2 buttons Copy data from graph into a text style file.

I am trying to simulate manual interaction with Wireshark IO graph and the capture button.

right now I am using the following:

• tshark -r myfile -2 -w 10.0.2.15.dst -R "ip.dst == 10.0.2.15"
• tshark -r myfile -2 -w 10.0.2.15.src -R "ip.src == 10.0.2.15"
• tshark -q -z io,stat,10 -r 10.0.2.15.dst > 10.0.2.15.dst.txt
• tshark -q -z io,stat,10 -r 10.0.2.15.src > 10.0.2.15.dst.txt

The problem is I need wall clock time I would like to simulate the data generated by IO Chart in batch mode that would show Recorded Time, IP=dst, IP=src

I need wall clock time so I can compare results on other activities within the lab. If I could have an output of the first and last entry based on wall time I could re-calc the back into something useful.
