Grafana Agent v0.40 introduces enhanced customization options with the addition of custom components and a revamped module configuration system, aimed at simplifying the configuration process for users. Custom components allow users to create reusable components by utilizing existing elements and the standard library, which is particularly useful for tasks like reusing specific URLs across different pipeline stages. The release also includes Modules 2.0, which facilitates configuration reuse among multiple pipelines, especially in environments like Kubernetes, by enabling standardized labeling across applications and infrastructure. This update supports remote updates via import functions, allowing Grafana Agent to automatically load changes, and encourages community feedback through Grafana Labs Community Slack and the Agent repository. Grafana Cloud offers an accessible entry point for users with a free tier for managing metrics, logs, and more.
