10 Best Synthetic Monitoring Tools in 2022

Better Stack Team
Updated on May 4, 2022

Synthetic monitoring is a part of APM, or application performance management, set of practices. Meaning, that it serves to ensure that you will always deliver the expected level of performance to your customers. By itself, synthetic monitoring is a pretty vast term, since it includes dozens of practices of website and server monitoring solutions. However, it could be best described as bots, or intelligent scripts, that simulate real human behavior patterns to the point of failure, and that's good. Because if your bot encounters an error before your human customer, you have time to fix it. Synthetic monitoring tests your website, web services, APIs or servers under different conditions like geolocation, time of the day, type of device/browser, or applies a behavior specific to a certain customer type based on other metrics.

Synthetic monitoring vs RUM

In synthetic monitoring you simulate the interaction with your customers - you create a synthetic scenario, in real user monitoring, you collect data from the customer to service interaction. RUM is therefore a passive testing method, meaning, that you have to wait for a customer to start collecting data, Synthetic monitoring is scheduled, but also independent and faster, so in many ways more reliable. It is a proactive approach to monitoring. You can read more about synthetic monitoring in our community guides.

How can synthetic monitoring benefit your project?

Keep your word - verify SLAs

Service level agreements or the SLAs are essential, the modern-day gentleman's word keeping your good reputation on the line. You need to understand what is your software actually capable of, how well it performs and if it performs sufficiently. All this can be found out via synthetic monitoring.

Keep an eye on your partners

Synthetic monitoring allows you to monitor if you deliver the promised quality of service, not only from your side, but also from the side of your partners. With synthetic monitoring you can keep an eye on all your third-party partners like payment processors, business analytics solutions, or various plugins. Their performance significantly affects the final result, and therefore, client satisfaction, so you better keep an eye on them. Trust, but verify.

Prepare for expansions and overloads

Synthetic monitoring helps you benchmark and baseline your software architecture. Benchmarking helps you to understand how effective your service actually is under different circumstances (like time of the day, location of your clients, number of requests, etc.), to estimate its performance after modifications or transitions, and to reveal its strong and weak aspects.

Understand, what it's like to be your client

Sometimes, you are just way too close to the problem and can't see the bigger picture. After all, how could you, you made the project, you know almost every line of the code. While that's great, it could also be a problem. Try to actually work with your own architecture from the user’s perspective, try different browsers, try different hours, locations, requests. And try dozens of different combinations.
