The New Relic One observability platform is now programmable, allowing users to connect their observability data to their business and make data-driven decisions. The platform provides tools for building custom applications that can analyze and visualize data from various sources, including third-party open-source data. Three popular contributed apps are highlighted: Top, Datalyzer, Browser Analyzer, and Cloud Optimize, which offer interactive views of data, process monitoring, customer experience analysis, and cloud instance optimization, respectively. These apps can be deployed locally or through the New Relic One CLI with a paid account and supported browser. The platform also welcomes contributions from the community, with resources available for building custom applications and using the GraphQL API.
