Synthetic Monitoring Management Using Playwright, @elastic/synthetics and Semaphore

Developers and Site Reliability Engineers (SREs) traditionally use different tools to emulate user workflows, with Synthetic Monitoring and End-to-End (E2E) testing being key approaches used by each group respectively. This text highlights the importance of unifying these processes under DevOps principles to enhance application stability and user experience monitoring from development to production. Synthetic Monitoring, which involves executing automated scripts to check application availability, can be used throughout the software development lifecycle to preemptively identify issues. E2E testing, on the other hand, mimics user actions to ensure workflows function correctly before changes are deployed. By leveraging tools like @elastic/synthetics, Playwright, Semaphore, and Elastic Synthetics, both developers and SREs can collaboratively validate and monitor user journeys using a single set of tools. This alignment not only improves the reliability of software deployments but also fosters a shared understanding of user-exposed features. The integration of these tools into CI/CD pipelines further supports consistent application monitoring, enabling quick identification of failures and performance issues in production environments.
