I'm only replying to state that this post is incorrect as I'm reading through this thread. If someone has already pointed this out later in the thread I apologize.

Parsers look at a .log file text document which you're receiving from the server, they don't interact with server network traffic at all. They look at when incoming damage posted in the log and then do math to give you a slightly behind look at damage being done real time from the messages as they're added to the log. Technically anyone could do this without a parser if they wanted to open up a spread sheet and take the relevant information.
