    Container monitoring with Grafana: Helpful resources to get started

    Containers enable consistent application performance across different environments and are often organized into microservices for better efficiency and scalability. Grafana is a powerful tool for monitoring these containerized environments, offering capabilities to visualize, query, and analyze metrics and logs. Comprehensive documentation is available for deploying Grafana with Docker, Kubernetes, and Helm Charts, covering configuration, customization, and troubleshooting best practices. The community is also invited to contribute feedback and join the Grafana Champions program to support wider documentation efforts.

    Memory Leak Profiling and Pinpointing for Node.js

    We identified and fixed a memory leak in a Nest.js application running on Kubernetes, which was caused by open handles not being properly closed during proxy requests to Grafana. Using Prometheus and Grafana for monitoring, along with custom modifications to the wtf-node dependency, we pinpointed the issue and adjusted the middleware to prevent the memory leak. Key steps include integrating prom-client with Grafana and using wtf-node to diagnose active handle issues.

    Grafana dashboards are now powered by Scenes: big changes, same UI

    Grafana has migrated its dashboard architecture to use the Grafana Scenes library, making the dashboards more stable, dynamic, and flexible while maintaining the familiar UI. This change enables several improvements, such as a new `Edit` mode, fixed positioning for template variables and time picker, faster PDF export times for enterprise users, and additional features like the `timezone` parameter in URLs and Kiosk mode enhancements. Despite the significant under-the-hood changes, users will experience a consistent interface with enhanced performance and new functionalities.

    Grafana's Prometheus libraries: How we built libraries to create a truly vendor-neutral data source

    Grafana Labs has decoupled its Prometheus data source from Grafana, enabling the creation of vendor-neutral data sources. This update includes a dedicated Amazon Managed Service for Prometheus plugin while maintaining core functionalities and stability. The change aims to foster better observability and reusability in the open-source community. Key principles like DRY and modularity were emphasized, and significant efforts ensured the code's independence and scalability. The project required extensive internal collaboration, POCs, and CI/CD enhancements to achieve this milestone.
