Hello Abhishek,
I don't think there is a feature available with DevTest that would allow you to keep a record of all the transactions ID with a service image file.
The VSI is a XML file. You should be able to open it using a text editor, Notepad++ for example.
When opening it, you will see something like:
...
<t id="9" nd="true" ads="true">
<sp>
<t id="16">
<rq id="17" op="addUser" tl="EXACT">
...
Where t id=9 is the transaction ID (META), and t id=16 is the specific transaction ID.
Hope it helps.
