Synthetic monitoring

Synthetic monitoring is the process of using scripted transactions to simulate user behavior on a website or an application to identify and fix performance issues before they affect end users.

Using Site24x7's synthetic monitoring tool, you can record your important transactions with our robust recorder, playback the recordings on a real browser and analyze the performance, and functionality of all critical components that can help in delivering better site reliability and end-user experience.

Synthetic transaction monitoring

Detect and resolve issues for an optimal site experience

Simulate transactions

Use our browser extension to record critical business transactions, and check them from multiple locations by simulating traffic. Record typical user paths or actions like a form submission, add to shopping cart, or import Selenium IDE test scripts, and play them back at regular intervals on a real browser like Chrome or Firefox to ensure an error-free experience for your users.

API monitoring

Add JSONPath or XPath assertions to validate responses for APIs underpinning your mobile and web apps. Extract variables from a previous response, and create a chained API request to test real business workflows. Expand your coverage. Download our mobile network poller and test your mobile app APIs via networks provided by wireless carriers.

Proactively address issues

Quickly check whether the new functionalities of your web application and internal websites are working as expected by running tests from within your private network using our locally installable on-premise poller software.

Synthetic monitoring tool

Reduce the risk of downtime going unnoticed

Monitor site availability

Synthetic monitoring runs tests at periodic intervals as low as one minute from more than 120 global locations against your websites, APIs, and web applications to ensure a successful response. You can leverage historical data to identify monthly trends and seasonality.

Verify response

Use regular expression patterns or strings to check for the presence of a value in the returned response body. You can also verify web server configuration by adding response headers.

Go beyond website uptime

Monitor dependent resources like DNS servers, SSL certificates, mail servers, WebSocket endpoints, and more to get a complete view of all the resources powering your service

Synthetic performance monitoring

Benchmark and improve site speed and performance

Waterfall analysis

Understand the loading behavior of your page. Get a visual representation of all requests your page makes with timing breakdown and order.

Optimize every byte

Identify resources—CSS, web fonts, images, and JavaScript—that detrimentally affect loading and rendering performance.

PageSpeed Insights

Don't know where to start? From an efficient caching policy to deferring parser blocking resources, get all the recommendations you need to deliver better performance

  • Capturing the availability and performance of web transactions through Firefox or Chrome web browsers.
  • Recording web interactions with a robust recorder tool and replaying the results using a real browser to evaluate the end-user experience.
  • Improving the end-user experience by detecting and resolving potential transaction issues.
  • Providing your monitor's current operational status in the Site24x7 web client.
  • Graphically interpreting key metrics, such as transaction or page load time, obtained from various locations for analysis.

Synthetic monitoring overview

What is synthetic monitoring?

Synthetic monitoring is a way to monitor websites, APIs, web, or mobile applications, and intranet sites using simulated user actions without relying on real-user traffic. IT admins and webmasters use it to perform basic checks or complex simulations to ensure optimal site performance. Read the detailed introductory guide on synthetic monitoring to learn more about Site24x7's synthetic transaction monitoring tool.

Depending on the resources you wish to monitor, a comprehensive monitoring tool can offer different synthetic tests for uptime, web performance, and transactions.

  • Uptime Monitoring: Uptime monitoring checks the availability of a website. You can monitor websites (HTTP and HTTPS monitoring), REST APIs, DNS servers, ping, WebSockets, TCP/IP ports, email servers (SMTP, POP, and IMAP), NTP servers, and UDP ports.
  • Web Performance Monitoring: Web performance monitoring analyzes the performance of a website and its various page elements to improve page load time, reduce downtime, and provide a better end-user experience. With performance monitoring, you can monitor FTP, webpage speed, and email server RTT.
  • Transaction Monitoring: Transaction monitoring helps ensure that the application or website functions without any interruptions. Checking API responses, monitoring APIs in sequence, and analyzing web transactions are examples of transaction monitoring.

Synthetic monitoring is crucial for maintaining end-user satisfaction and brand value, and it provides a proactive approach to monitoring the performance and availability of websites and web applications. Here are some benefits of synthetic monitoring:

  • Ensure the availability of websites and web applications.
  • Resolve issues before they impact end users.
  • Analyze page load time and response time.
  • Check the performance of page assets and third-party services.
  • Establish realistic SLAs and hold third-party providers accountable for any breaches.
  • Track website performance during low-traffic hours.
  • Identify potential glitches during the pre-production stages.
  • Measure and compare baseline website performance to competitors.

Synthetic monitoring tool uses simulated transactions to provide valuable insights into the performance of websites, applications, and APIs. Here are the steps involved in synthetic monitoring:

  • Synthetic monitoring simulates user interactions with a website or application to assess performance.
  • Paths are created to replicate user actions on the site.
  • These paths are regularly monitored at set intervals from various operating systems and global locations.
  • The monitoring tests evaluate factors like functionality, availability, and response time.

Synthetic monitoring can be performed during both peak and low-traffic periods to obtain a comprehensive understanding of site performance.

Synthetic monitoring helps you identify and address various challenges in the IT and software development landscape. It helps you ensure that applications and websites perform well under various conditions, understand how real users experience workflows on a website or application, minimize downtime, guarantee the high availability of systems, and speed up issue identification and incident resolution.

With a synthetic monitoring tool, you can obtain

  • Proactive issue identification

    With synthetic monitoring, you can detect issues before they affect end users. By simulating user interactions and transactions at regular intervals, you can track and rectify performance bottlenecks, downtime, or functionality issues.

  • Around the clock monitoring

    Regardless of real-user traffic, constant vigilance ensures that your website or application is always available and performing optimally, even during off or peak traffic hours.

  • Multi-location perspective

    Understanding how your application performs across different geographies is crucial for global services striving to deliver a consistent user experience regardless of user location.

  • Performance benchmarking

    Consistent testing of your website or application allows you to benchmark its performance over time. This is valuable for tracking the impact of code changes, infrastructure upgrades, or third-party services on your site's responsiveness and loading times.

  • Comprehensive root cause analysis

    These advanced synthetic monitoring tools provide detailed reports and analytics, making it easier to perform root cause analysis for the identified issues. This helps you to achieve long-term improvements by efficiently fixing issues and optimizing the website.
