What is Synthetics Monitoring?

Synthetics monitoring, also known as synthetic monitoring or active monitoring, is a powerful technique used to monitor the performance, availability, and functionality of applications, websites, APIs, and other digital services. Unlike traditional monitoring methods that rely on real user interactions, synthetics monitoring involves simulating user behavior and transactions to proactively test and monitor critical workflows.

In synthetics monitoring, synthetic transactions are created to mimic user actions, such as visiting web pages, submitting forms, clicking buttons, or interacting with APIs. These transactions are performed at regular intervals from various geographical locations, enabling organizations to gain insights into the end-to-end performance of their applications and identify potential issues before they impact real users.

The primary goal of synthetics monitoring is to ensure that applications and services meet predefined performance and availability thresholds. It allows businesses to detect and address issues like slow response times, downtime, broken links, and other performance-related problems that could lead to a poor user experience.

Synthetics monitoring plays a crucial role in the overall monitoring strategy, complementing other monitoring techniques such as real user monitoring (RUM) and server monitoring. While RUM provides insights into the actual user experience, synthetics monitoring offers a proactive approach by simulating user interactions and validating critical workflows from predefined locations.

By leveraging synthetics monitoring, organizations can gain valuable data to optimize application performance, improve reliability, and enhance the overall user experience. It enables teams to identify and resolve issues in a timely manner, minimizing the impact on users and maintaining the reputation and trust of their digital services.

In the context of New Relic, a leading observability platform, synthetics monitoring is a core feature offered through New Relic Synthetics. It provides users with the ability to monitor applications and services proactively, helping them ensure optimal performance, identify bottlenecks, and deliver exceptional user experiences.

How does Synthetics Monitoring work?

Synthetics monitoring works by simulating user interactions and transactions to monitor the performance and availability of applications, websites, APIs, and other digital services. Here\’s a high-level overview of how synthetics monitoring typically functions:

  • Define Synthetic Transactions: In synthetics monitoring, you start by defining the synthetic transactions or workflows that you want to monitor. These transactions could include actions like loading a webpage, submitting a form, clicking buttons, or making API calls. You specify the steps involved in each transaction and the expected outcomes.
  • Configure Monitoring Settings: Once you have defined the synthetic transactions, you configure monitoring settings such as the frequency at which the transactions should be executed, the geographical locations from which they should be performed, and the thresholds for performance metrics (e.g., response time, availability) that indicate potential issues.
  • Synthetic Agents: Synthetic agents or bots are deployed across different geographical locations or cloud providers. These agents are responsible for executing the synthetic transactions as defined in the monitoring configuration. They simulate user behavior by interacting with the applications or services and recording the response times, error rates, and other relevant data.
  • Transaction Execution: At regular intervals, the synthetic agents execute the defined transactions from their respective locations. They measure the response time, capture any errors or failures encountered, and collect performance data such as network latency, DNS resolution time, and server response times. These metrics provide insights into the health and performance of the monitored applications.
  • Alerting and Reporting: As the synthetic transactions are executed, the monitoring system compares the measured metrics against the predefined thresholds. If a transaction exceeds the specified thresholds or encounters errors, alerts are triggered to notify the relevant teams or stakeholders. Detailed reports and dashboards are generated to provide a holistic view of application performance over time.
  • Analysis and Troubleshooting: When alerts are triggered or performance issues are detected, teams can analyze the monitoring data to identify the root causes. They can investigate the specific steps of the synthetic transactions that experienced delays or failures, helping them pinpoint the areas that require attention. This analysis aids in troubleshooting and taking proactive measures to resolve issues and optimize performance.
  • Continuous Improvement: Synthetics monitoring enables organizations to continuously monitor their applications and services, gaining valuable insights for ongoing optimization and improvement. By analyzing the collected data, teams can identify patterns, trends, and potential bottlenecks, allowing them to make informed decisions to enhance the user experience and ensure reliable service delivery.

Why should you use Synthetics Monitoring?

Synthetics monitoring offers several compelling reasons for organizations to incorporate it into their overall monitoring strategy. Here are some key benefits of using synthetics monitoring:

  • Proactive Issue Detection: Synthetics monitoring allows you to proactively detect and address potential issues before they impact real users. By simulating user interactions and monitoring critical workflows, you can identify performance bottlenecks, slow response times, and other issues that may degrade the user experience. This proactive approach enables you to take corrective actions early, minimizing the impact on your users.
  • End-to-End Application Visibility: Synthetics monitoring provides end-to-end visibility into the performance and availability of your applications. By monitoring from multiple geographical locations, you can assess how your applications perform in different regions and ensure consistent user experiences globally. It allows you to gain insights into network latency, DNS resolution times, server response times, and other performance metrics that can affect user satisfaction.
  • Validation of Service Level Agreements (SLAs): Synthetics monitoring helps you validate and enforce your service level agreements (SLAs) with your customers or stakeholders. By continuously monitoring and measuring performance against predefined thresholds, you can ensure that your applications meet the agreed-upon service levels. It provides objective data to demonstrate compliance and maintain customer satisfaction.
  • Improved Incident Response and Troubleshooting: When incidents or performance issues occur, synthetics monitoring data can be invaluable for incident response and troubleshooting. By analyzing the monitoring data, you can pinpoint the specific steps or transactions that are experiencing delays or failures. This information helps in identifying the root causes and taking prompt corrective actions, minimizing downtime and improving mean time to resolution (MTTR).
  • Benchmarking and Performance Optimization: Synthetics monitoring enables you to establish performance benchmarks and track progress over time. By collecting historical data and comparing performance metrics, you can identify trends, patterns, and areas for improvement. This data-driven approach empowers you to optimize application performance, enhance resource allocation, and prioritize performance enhancements based on real usage scenarios.
  • Enhanced User Experience: Delivering exceptional user experiences is paramount in today\’s digital landscape. Synthetics monitoring helps you ensure that your applications are performing optimally and meeting user expectations. By proactively monitoring critical workflows, you can identify and address issues that may impact user satisfaction, such as slow page load times, broken functionality, or downtime. This leads to improved customer retention, higher conversions, and a positive brand reputation.
  • Insights for Capacity Planning and Scalability: Synthetics monitoring provides valuable insights for capacity planning and scalability initiatives. By monitoring application performance under different loads and transaction volumes, you can identify performance bottlenecks and determine the optimal infrastructure requirements. This helps you plan for future growth, allocate resources efficiently, and ensure that your applications can scale seamlessly to meet increasing user demand.
