 Datadog Synthetic Monitoring (FREE TRIAL)

Datadog Synthetic Browser Test

Datadog provides cloud-based infrastructure and application monitoring services. Its Synthetic Monitoring package specifically focuses on web monitoring and performance testing features. Datadog Synthetic Monitoring tests are run from servers around the world.

Key features:

  • Performs uptime and response time monitoring from several locations around the world.
  • Enables user-journey modeling to check for load errors, programming mistakes, and poor website design.
  • Enables website tests to be compiled through browser recording.
  • Uses AI methods to vary user journeys during test runs.
  • Tests are run through actual browsers for real-life user experience modeling.

Datadog’s tests emulate user access rather than recording events during real user visits. This is a useful tool for checking important performance metrics on a new web page, such as response timesload error rates, and programming issues. Constant availability and latency tests highlight potential delivery problems such as load balancing or queuing problems. The tool will also log whenever the site becomes available. Uptime record-keeping is particularly important for those who need to prove compliance with SLAs.

The screens of the performance monitor include some great visualizations. An example is the waterfall root cause analysis view, which displays how one problem impacts many performance metrics. The service can pinpoint whether the performance deterioration is due to network issues, coding errors, or server problems.

Although the Datadog Synthetic Monitoring service performs its own check, you can design customized tests by recording walk-throughs. These simulations will then be implemented on the many Datadog testing servers to record the response-times of your webserver to those specific actions that you want to test. This is a great feature that will help you trial new features on a website to ensure that adding a button or a graphic won’t slow down the loading or navigation performance of that page.

The standard tests aren’t just repetitions of the same access runs. Datadog includes AI-based machine learning techniques that proactively seek out features in a page and attempt every combination of execution. Over time, tests establish what should be considered a typical performance of your site. This enables you to see a log of expected response times and it also adjusts alert thresholds so that you aren’t pestered by an overactive alerting system.
