Metrics, Sentry's new beta feature, is now available to help developers track key performance indicators (KPIs) and resolve issues quickly. It provides a unified platform for monitoring metrics, tracing, and debugging, allowing teams to pinpoint problems with correlated traces. With Metrics, users can create custom metrics, visualize data points over time, and set alerts to notify them of anomalies. The feature integrates seamlessly with Sentry's Performance offering, enabling developers to measure specific performance metrics and take action when issues arise. By providing a comprehensive solution for monitoring and debugging, Metrics aims to streamline the development process and improve overall product quality.
