It really depends on what you are trying to do and what you are willing to spend. If you are looking for APM, take a look at New Relic. I've used both in production at similar (~1m requests/hour (DD) and ~10m requests/hour (NR)) scales. They are both good and expensive. If you just want logs, metrics, dashboards, and alerts, there are tons of alternatives that are cheaper and better.
