Engineer at Airbnb, but unrelated to this launch. We use both products extensively internally; datadog for custom metrics deployed next to features and alerts in code (https://github.com/airbnb/interferon https://github.com/airbnb/interferon), and New Relic for opinionated application health/performance and client side monitoring. Two talks we've done about our usage of Datadog and New Relic (respectively): https://www.youtube.com/watch?v=MYmVu_IMC20 https://www.youtube.com/watch?v=MYmVu_IMC20 https://www.youtube.com/watch?v=fd_Kla4f86E https://www.youtube.com/watch?v=fd_Kla4f86E Disclaimer: I'm the presenter in the second talk.
