Mastra's New Integration with Arize AX and Phoenix for TypeScript Agents

If you are building agents with TypeScript... Mastra now integrates directly with Arize AX and Arize Phoenix! This means your agent traces automatically stream into Arize AX with minimal extra setup. You can start running evals right away. In the video, I walk through how to: - Instrument your agents for tracing - Define trace and span evaluations - Configure online evals that automatically run as your agent executes I’ve found this workflow to be a simple but powerful way to close the loop between building, observing, and improving agents.
