Building an observability system that provides accurate alerts with a high signal-to-noise ratio can be overwhelming, especially when maintaining configurations across a large organization. To address this challenge, software teams are adopting the practice of "observability as code," which treats observability ecosystem configurations as code and automates their management through infrastructure as code (IaC) tools like Terraform. The New Relic Terraform provider allows teams to define and provision their New Relic resources in a declarative language called HCL, enabling them to create monitoring and alerting configurations that can be easily managed and updated through automation. By using Terraform and the New Relic provider, teams can define alert policies based on four golden signals of monitoring (latency, traffic, errors, and saturation) and link them to notification channels, making it easier to manage their observability system in a scalable and maintainable way.
