AppDynamics Business Transactions represent the critical end-to-end paths that a user request follows through an application, such as login, checkout, or search operations. Instead of monitoring isolated technical components, Business Transactions focus on how these real user actions perform across services, databases, APIs, and backend systems. This approach makes it easier to pinpoint where slowdowns or failures occur within the full application flow. They matter because they bridge the gap between technical performance and business outcomes, allowing teams to prioritize issues based on real customer impact. By monitoring response time, errors, and throughput at the transaction level, organizations gain clearer visibility, faster troubleshooting capabilities, and improved user experience, ultimately supporting better performance and revenue protection.
