GrayLog Newcomer Questions

Hello Graylog community!,

I am a new system administrator that will be working with Graylog, however, I do have some questions on some situations that I need to debug quickly:

How do you debug a DoS or similar attack?, the think is that we hold several sites on one server so, querying gets a little messy, and identifying one of these attacks gets hard.

Are they any good ways to tag certain ‘anomalies’, programming language exceptions or other useful debugging information?, for example, if I have a request for nginx that generated an exception so, it returned server error as a response, how can I ‘link’ these together so I can debug successfully?.

Thank you in advance for looking into my question, looking to learn the most of this amazing tool!
