I'm getting an 500 error on my azure and I don't understand why. I can't find any information whats wrong except the following line:

2016-01-18 15:12:03 NOTESERVICEGERT POST /Document/Update X-ARR-LOG-ID=6011311d-7560-4d87-bccf-a411a03e2a0d 80 - 194.88.2.202 - - - noteservicegert.azurewebsites.net 500 0 0 489 27040 9344

What is an X-ARR-LOG-ID and what kind of information can I get regarding this request?

This is the IIS log, which cannot in itself tell the whole story. Most likely, your code was reached, and for some reason it returned a 500. e.g. it could happen if some exception was thrown in your code.

To get more information when that happens, you will need to enable Application logging and detailed error logging. This article describes how.
