Description

This example demonstrates how to integrate Galileo observability with a Mastra agent project. The example is based on Mastra's CSV to Questions Generator template and has been updated to support the latest version of Mastra using the new observability property configuration with OTel exporters. The agents process CSV files from URLs and generate comprehensive questions using OpenAI GPT-4o, with full trace logging to Galileo.
