All Developer, Team and Business plan customers can send Metrics from the JS/Python code and track these Metrics in Sentry.

• Send counters, gauges, and distributions from your code to track things like email.sent, checkout.failed, queue.depth etc
• Easily Visualize and aggregate these metrics in Explore->Metrics
• See all relevant traces - So just zoom into any dip/spikes and find traces that contain errors, spans or logs to help you debug better
• Save your queries for quick reference later
