Are log parsers ok or are they in violation of the rules?

[Sinaz]

As the title says, is it ok to create and use log parsers or are they against the rules?

Specifically im looking to build a real time log parser to automatically keep track of buff durations. This will only access the physical eqlog.txt file on the local machine and nothing else.

Would be great to get an official Yay or Nay.

Cheers
