Graflog

In a distributed system, logging is hard. In order for distributed logging to be useful, it needs to contain metadata about what caused it. Ideally, a given logged event should tell us:

• what user input caused it
• what API call caused it
• whether it is an error or not
• its severity
• a correlative id that allows us to find other log events related to it

Graflog is primarily focused on the last piece.
