Seagence is a tool that helps developers detect and debug concurrency issues in Java applications by analyzing how requests are processed in real-time. It integrates with Datadog, allowing developers to track defects as events and visualize the root cause in out-of-the-box dashboards. The integration includes a preconfigured monitor that can notify users about Seagence's findings in real time. By using Seagence and Datadog together, developers can proactively detect and debug code-level issues in their Java applications before they affect end users.
