Checkly is a tool that helps engineering teams shorten their mean time to detection (MTTD) and resolve incidents faster by using synthetic monitoring, which simulates real user paths through an application to reveal integration problems with third-party services. Checkly Traces provides backend data to help diagnose root causes of issues, reducing the mean time to resolution (MTTR). By integrating backend data with synthetic monitoring, users can get a complete view of their service's performance and identify potential issues before they become major problems. This allows teams to respond quickly and effectively to incidents, maintaining their Service Level Agreement (SLA) with users. With Checkly Traces, teams can reduce their time to detection, diagnose root causes more efficiently, and resolve incidents faster with minimal resource demands on network and storage.
