The combination of Tracing, Logs, and Application Metrics is what moved Sentry beyond basic error monitoring for us. Since the .NET SDK began supporting metrics and Application Metrics became generally available, we’ve been able to track counters, gauges, and distributions, break them down by attributes like region or plan, and then pivot from an anomaly straight into the related trace, log, or error—without having to manually line up timestamps across multiple systems. We ran into this recently when auth failures started creeping up. The metric made the trend obvious, but the real value was being able to jump into the affected requests and see exactly where the failure was occurring. Monitors & Alerts have also become easier to manage because the signal and the notification path can be handled separately. A threshold can create an issue with the right context, while Slack, email, or PagerDuty routing is maintained independently. That separation helped us eliminate several duplicated alert rules that had slowly accumulated across projects. Cross-Event Querying is another feature I’m using more during technical reviews now, not only after incidents. Being able to search across spans, logs, and metrics makes it much easier to investigate a suspicious pattern early, before it turns into something urgent. The API improvements around traces, profiles, and attachments have also been helpful when we want to pull parts of that investigation into our own internal tooling, rather than forcing every workflow through the dashboard.

Sentry makes it easier to find and fix bugs; everything is clean and fast in that software.

What I like most about Sentry is how effectively it helps me identify and fix issues in real time. Its error tracking is very thorough, with clear stack traces, helpful context, and visibility into user impact, which makes debugging much faster. The performance monitoring and alerts also make it easier to catch problems early, before they affect too many users. Overall, it saves developers a lot of time and helps improve application reliability.
