Grafana Labs has introduced Grafana Phlare, an open-source database designed for continuous profiling at a large scale, which integrates seamlessly with Grafana's existing tools like metrics, logs, and traces. This new backend aims to provide scalable, highly available storage and querying of profiling data, offering features such as native multi-tenancy and integration with object storage solutions like Amazon S3 and Google Cloud Storage. By visualizing profiling data alongside other data sources in Grafana, users can gain a comprehensive view of their systems, enhancing application performance and optimizing infrastructure costs. The release follows Grafana Labs' acquisition of Pyroscope and aims to address the challenges of continuous profiling in distributed, cloud-native environments, positioning it as the fourth pillar of observability. Grafana Phlare's ease of installation and its compatibility with various storage solutions make it a versatile tool for teams across different business units. The project reflects Grafana Labs' commitment to open source and community collaboration, with ongoing developments to enhance query capabilities and support profiling without application instrumentation.
