I'm a borderline fanboy at this point
What do you like best about the product?
Datadog is building out a platform that covers not only all logging and monitoring needs, but also integrates them together nicely. The interface has a consistent feel, and the support staff is generally well-above averagee.
What do you dislike about the product?
It is a bit on thee pricey side in some areas -- there are a lot of competitive open-source solutions but I'm thankfully at a business that allows us to get tools like this.
What problems is the product solving and how is that benefiting you?
We are leveraging Datadog for general metrics, APM, and as of recently... logs. The ability to view associations between these pillars is a great benefit that we didn't have when using separate tools.
