New Relic One is an observability platform built to help engineers create more perfect software. From monoliths to serverless, you can instrument everything, then analyze, troubleshoot, and optimize your entire software stack. Before you start, you should already have a NewRelic account and your environment setup and running. If not, head over to NewRelic to get things started. Once you're done, return to Sleuth so you can complete setup of the integration.
