When you do not know what you are looking for

A multi-agent workflow in CrewAI, which used to take 90 seconds to complete, now takes four minutes without any apparent issues, prompting an investigation using a new metrics browsing feature that simplifies the process of identifying performance degradations. This feature allows users to select a namespace and a metric without needing SQL, providing visual breakdowns to quickly pinpoint issues, as demonstrated by tracing a retrieval latency issue back to a fragmented index that, once reindexed, restored the workflow to its original speed. The system groups metrics by namespaces like http or system and offers a seamless transition from discovery to detailed SQL analysis, ensuring users can efficiently identify and resolve performance problems without learning new query languages. The Metrics explorer is available for all Logfire projects, with precautions for avoiding double-counting in host metrics and a reference guide for automatically-collected metrics, and the platform also offers a free tier for new users.
