What is Synthetic Transaction Monitoring?

Synthetic transaction monitoring, or web application monitoring, is a proactive method designed to measure and test web application performance through simulated transactions. Synthetic monitoring evaluates web application performance by simulating user interactions. During these simulated interactions, synthetic monitoring tools collect data on the web application's performance, including responsiveness and load times. This approach is about identifying and preventing issues before they affect end users.

Synthetic monitoring proactively detects performance bottlenecks. By replicating the end user's experience, synthetic monitoring assesses the application's performance to identify potential issues before they impact users. Custom scripts simulate user actions in business-critical scenarios, identifying potential issues before they affect users. Configured to operate both within a company's network and from external locations, synthetic monitoring provides comprehensive performance insights.

Synthetic monitoring tools:

  • Execute tests continuously, tracking performance around the clock.
  • Assess an application's responsiveness and availability from various geographic locations.
  • Provide businesses with a holistic view of their application components' performance.

How does Synthetic Transaction Monitoring Work?

Synthetic monitoring (a.k.a. web transaction monitoring) involves a robot client application that automates user transactions, simulating real user interactions with a website or application. This process generates network traffic and server calls to simulate real user activity and test application responsiveness. It is essential for identifying potential issues before they affect actual users. TEA (Transaction Execution Agents) play a crucial role in this setup by executing the scripts and reporting the results, ensuring that the simulated transactions closely mimic real user behavior.

One key advantage of synthetic monitoring is its ability to test application behavior from various geographical locations, including multiple locations. Synthetic monitoring can be configured to test interactions with remote servers and within different test environments, helping to identify issues before they impact customers.

It is important to whitelist the IP addresses used by synthetic monitoring tools to ensure that security systems or firewalls do not block the tests, which could otherwise prevent accurate performance assessments. Strategically chosen monitoring locations allow businesses to assess application performance across different locations, offering a comprehensive view of potential issues.

Continuous testing with synthetic monitoring tools ensures consistent application performance monitoring. This ongoing assessment alerts businesses to service outages or performance degradations promptly, facilitating quick responses and minimizing downtime with a robust monitoring system.

Types of Synthetic Transactions

Synthetic transactions come in various forms, each serving a specific purpose in assessing application performance. API monitoring, for example, includes methods that assess the availability and performance of specific api endpoints used by applications. Synthetic tests within API monitoring can include HTTP, SSL, and DNS tests, ensuring that different aspects of API functionality are monitored. Additionally, synthetic monitoring can test web services as part of transaction scripts to verify that APIs and related web services are functioning as expected.

Browser tests are another critical type of synthetic transaction. These tests simulate user actions in an actual browser monitor, allowing for the evaluation of webpage functionality and performance across different browsers. Browser tests also monitor client-side performance metrics, such as page load times, to ensure optimal user experience. By mimicking real user interactions, browser tests help identify any issues that might affect the user experience, ensuring that web pages perform optimally.

Multi-step user journey simulations provide insights into how different user interactions unfold. These simulations are crucial for identifying bottlenecks within complex workflows, ensuring that the entire user journey is seamless and effective. Synthetic monitoring can simulate the end user's clickstream to track web transactions and interactions within a web app, helping to identify issues at each step. By tracking a complete workflow of an application process, multi-step API tests ensure that everything functions correctly from start to finish.

What is the Difference between Synthetic Transaction Monitoring and Real User Monitoring?

Synthetic transaction monitoring and real user monitoring each offer unique advantages in web application monitoring. Synthetic monitoring lets organizations identify performance and user experience issues before they impact real users. Synthetic monitoring can proactively identify issues and provide immediate alerts about service outages by simulating user journeys in a controlled environment, enabling quick responses and reducing downtime.

In contrast, real user monitoring tracks actual user interactions, providing insights into how real users interact with the application and utilizing real user data. While synthetic monitoring can test scenarios in pre-production environments to ensure new features perform well before they go live, real user monitoring cannot operate in such environments. Integrating synthetic monitoring with real user monitoring and other analytics tools offers a comprehensive view of application performance and real user traffic.

One key benefit of synthetic monitoring is its ability to test new features in a controlled environment, ensuring they perform well before being released to real users. This proactive approach fosters collaboration between technical and non-technical teams by focusing on user-centric performance metrics. Combining synthetic and real user monitoring provides a holistic view of performance, capturing both simulated and actual user experiences.

By emulating user actions, synthetic monitoring ensures that potential issues are identified and addressed before they impact real users. This proactive monitoring, combined with the reactive insights from real user monitoring, creates a robust application performance monitoring strategy that ensures optimal user satisfaction.

Application Performance and Synthetic Monitoring

Application performance is at the heart of delivering exceptional digital experiences, especially for businesses that depend on web applications to serve their customers. Synthetic monitoring is a powerful technique that enables organizations to monitor web applications by simulating user interactions, such as logging in, browsing, or completing a purchase. Using synthetic monitoring tools, businesses can proactively identify performance issues before they impact actual users, ensuring a seamless experience even during low real user traffic periods.

One of the key strengths of synthetic monitoring solutions is their ability to monitor web applications from multiple locations around the globe. This approach provides a comprehensive view of application performance, helping to uncover issues that may only affect users in specific geographic locations or under certain network conditions. By monitoring web applications from different locations, organizations can ensure consistent performance for all users, regardless of where they access the service.

Synthetic monitoring tools also allow businesses to monitor specific workflows, such as checkout processes or login procedures, to verify that these critical paths function correctly. This targeted approach to monitoring web applications helps maintain high standards of reliability and user satisfaction. Ultimately, synthetic monitoring empowers businesses to deliver robust, high-performing web applications and maintain a competitive edge in today's digital landscape.
