The best part is, it allows us as developers or system administrators can monitor our applications in real time without having any technical expertise of stack state itself! It also provides all necessary metrics for business decision making which was not available earlier with other tools like New Relic etc. I would say there are no downsides at present but we will try harder if anything comes up during its use (it does have some learning curve). We used this tool from past 3 years now so far everything seems fine though nothing much new came out after using these few months only.
