Obtain Diameter Average Response Time with Wireshark

Obtain Diameter Average Response Time with Wireshark

To get the average response time of diameter credit control requests using wireshark do the following:

1. Open a capture file in wireshark

2. From the "Statistics" menu select "I/O Graph". If wireshark starts to parse the content you may cancel it.

3. On the "I/O Graph" window, under the "Y axis" section,  set for the Unit field the value "Advance"

4. On the "Graphs" Section we need to fill the fields as follows:

• Filter: (diameter.flags.request == 0 && diameter.cmd.code == 272)
• Calc select: AVG(*) type: diameter.resp_time

What we are doing here is that we are filtering all the requests and getting only the responses (diameter.flags.request==0) and making sure that the requests are credit control requests (diameter.cmd.code==272). 

5. Click on "Graph 1"

That's it.
