Monitoring response times helps you identify potential latency issues that might affect user experience. Understanding how your application behaves in different locations and under various loads is essential for delivering consistent and reliable service.

Monitoring Complex User Flows

Modern web applications often involve multi-step user interactions, such as logging in, navigating through complex workflows, or completing transactions. Synthetics can simulate these interactions by using scripted browser tests.

By setting up multi-step synthetic tests, you can monitor critical user flows and identify any bottlenecks or errors that may occur. This allows you to optimize the user experience and improve conversion rates.

Tracking API Performance and Functionality

For applications that rely heavily on APIs, monitoring API performance is of utmost importance. Synthetics Monitoring allows you to validate API endpoints and ensure that they meet your response time expectations.

By tracking API performance, you can gain insights into how your application interacts with external services and detect any issues that may arise from API latency or functionality.

Analyzing Synthetics Data and Reports

Identifying Performance Bottlenecks

After running synthetic tests over time, you’ll gather a significant amount of performance data. Analyzing this data helps you identify performance bottlenecks, such as slow-loading pages, inefficient database queries, or third-party service dependencies.

Identifying these bottlenecks enables you to prioritize optimizations and allocate resources effectively.

Troubleshooting Errors and Issues

Synthetics tests might occasionally detect errors or failures. When this happens, it’s essential to investigate the root cause promptly.

By examining the test results, logs, and any error messages, you can determine whether the issue lies with your application code, server configurations, or external dependencies.
