Synthetic monitoring feels like the safest layer in the observability stack. It uses artificial users. It runs scripted journeys. It never touches real customer accounts. Yet this is exactly why many teams overlook the privacy exposure hidden inside it. Synthetic tests often produce screenshots, network captures, HTML snapshots, console logs, authentication artifacts or even short screencasts.

Synthetic Transaction Monitoring is a technique that uses automated scripts to simulate user activities on an application to test performance and functionality. By using automated scripts, it creates fake transactions such as logging in, searching for a product, or completing a purchase without requiring real users. These transactions are executed regularly from various locations to ensure the application is performing smoothly and as expected, even during off-peak hours.

ServiceNow is one of those platforms that looks simple from the outside but turns into a labyrinth the moment an organization starts customizing it. What begins as a service catalog or an HR portal quickly evolves into a tangle of custom tables, UI policies, business rules, Flow Designer actions, and scripted REST endpoints. None of this is bad. In fact, it’s the whole reason companies choose ServiceNow: you can build anything.

To have a fast and reliable experience digitally you would need to do more than resolving issues. This is why people prefer synthetic monitoring which simulates real user actions with regular intervals. Using this method, businesses can detect performance shortcomings and any technical issues. From testing website load to full flow checkout, everything can be tested before users face any issues.

Modern IT teams know the story by heart: uptime dashboards look green, the public website is fast, yet somewhere inside the corporate network, the finance team can’t submit purchase orders and the factory floor’s ERP terminals are frozen. What broke isn’t the internet—it’s the internal backbone. These internal systems—SAP, Oracle, Microsoft Dynamics, homegrown ERPs, HR and payroll platforms—keep the business running.

Synthetic Monitoring is a proactive approach to testing a website or web server to ensure that digital services stay available, responsive, and functional at all times. Instead of waiting for real users to encounter a problem, synthetic monitoring uses automated scripts to imitate user interaction, such as visiting pages, submitting forms, or performing transactions from multiple global locations.

When an application slows down or fails, pinpointing the cause isn’t always simple. Is it a backend regression, a misbehaving API, or a bottleneck somewhere deep in the network? Without full visibility, teams waste precious time troubleshooting across disconnected tools and layers. Datadog Synthetic Monitoring now supports Network Path to help you proactively identify whether user-facing issues stem from your code or from the underlying network.

GraphQL isn’t just another API protocol—it’s a new layer of abstraction. It collapsed dozens of REST endpoints into one flexible interface where clients decide what data to fetch and how deep to go. That freedom is a gift for front-end teams and a headache for anyone tasked with reliability. Traditional monitoring doesn’t work here. A REST endpoint can be pinged for uptime.

Testing ecosystems contain massive amounts of data, including outlined test scenarios, prerequisite configurations, and the tests themselves. As a result, these ecosystems are prone to data sprawl. This makes it difficult to prevent configuration drift and quickly spin up new tests, especially at the frequency needed to support a fast-growing application. Teams can handle these challenges by treating their tests as part of their application infrastructure.

We've been running Playwright in production since the beginning. Today, we're going all in. When we first launched Browser Checks with Playwright support, we proved something critical: the most popular test automation framework since Selenium isn't just for testing—it's the foundation of modern production monitoring. But that was just the beginning. Today, we're announcing Playwright Check Suites—our bet on the future of monitoring and the most significant evolution in Checkly's history.
