Grafana Tempo 2.9 introduces a range of new features and improvements, including MCP server support, TraceQL metrics sampling, and enhanced operational capabilities for multi-tenant environments. The release marks the inclusion of Model Context Protocol (MCP) server support, allowing large language models (LLMs) to securely connect to tracing data, facilitating easier service diagnostics and interaction analysis. Additionally, the update offers probabilistic sampling in TraceQL queries to speed up data retrieval, albeit with a tradeoff in accuracy, and includes new metrics for monitoring query I/O and span timestamp discrepancies. Operational enhancements improve trace performance visibility in multi-tenant settings, and new features in the cost-attribution usage tracker allow for more specific resource and span-level tracking. Looking ahead, Grafana is developing an experimental vParquet5 block format and a new architecture, Project Rhythm, aimed at scalability and reduced ownership costs. Users are encouraged to engage with the community through Grafana Labs channels and consider the free tier of Grafana Cloud for accessing Tempo.
