New Relic One has introduced programmability to its observability platform, allowing users to connect their observability data to their business and make data-driven decisions. To demonstrate this, New Relic has created several open-source applications, including Status Page, GitHub Integration, Agent Groundskeeper, and Customer Journey, which can be deployed locally or in a New Relic account. These apps provide various features such as aggregating system status, integrating with GitHub, displaying real-time version information, and examining customer journeys. Users can deploy these apps using the New Relic CLI and require access to New Relic One, a personal API key, and Node v10 or higher. New Relic also provides resources for building custom applications, including the Developer Edition, GraphQL Explorer, and NR1 Workshop. The company welcomes contributions to its open-source projects and encourages users to join the Explorers Hub for support and discussion.
