Anything you don't measure or test, you cannot improve. The wisdom applies particularly to web as we develop our websites and applications. Without any kind of monitoring solution in place, you are flying blind.
To learn more about the topic, I am interviewing Siva Kaliappan from Sematext.
My name is Siva Kaliappan and I am the Product Lead for Sematext Synthetics. I primarily work on the Sematext Monitoring product line across all parts of the stack from the front-end, backend, and agents.
Lately, I have mainly worked on the design and development of Sematext Synthetics. I am also an open-source developer and author of the popular LogTrail Kibana plugin included in Sematext.
Sematext Synthetics is like your trusted user who monitors your APIs/websites 24x7 from multiple locations around the globe and alerts you when things go wrong. Sematext Synthetics also provides detailed reports on the availability and performance of your web applications.
At a high level, Synthetics works by periodically sending requests to your HTTP endpoints or launching your website in an embedded browser from multiple locations around the globe and recording various performance metrics and errors, if any. Then we check if the actual results meet the expectations and also persist the results for reporting.
As a user, you start by creating an HTTP or Browser monitor, specify the interval to run, list of locations to run the monitor from, monitor specific details, and a list of expected conditions for the monitor to pass.
An HTTP monitor is used to monitor HTTP endpoints like APIs or Web URLs. HTTP monitor sends a single HTTP request to the configured HTTP endpoints with specified request details and records the response and performance timings.
A browser monitor is used to monitor a web page or user journey. Browser monitor uses a Puppeteer API based script to drive an embedded Google Chrome browser. Sematext Synthetics runs the script and records the various performance timings and errors, if any. It also captures one or more screenshots of the loaded page for visual inspection.
One of the major differentiators for Sematext Synthetics is it being part of Sematext Cloud, the integration it provides with infrastructure monitoring, log management, and real user monitoring.
While you can independently use each of these solutions, you can reap the benefits of their tight integration. Each of them is just a click away makes debugging a lot faster & easier. And with the flexibility to create custom reports and have data from all the above in a single dashboard, you could create a completely customized view of your application performance that suits your needs.
After releasing Experience, our Real User Monitoring solution last year, we felt Synthetic Monitoring would be the right addition to Sematext Cloud.
Now with Synthetics, our customers can get end-to-end visibility of their applications from a single place. Also, we needed availability monitoring for our applications. We have been using Synthetics to monitor our applications and also found it uncovering issues with our APIs on a few occasions.
We have lots of exciting features lined up for Sematext Synthetics. Consider a part of our roadmap below:
And of course, we listen to our users and customers always and will be adding features based on their input, too.
We see more interest in below areas in the future concerning Synthetic monitoring:
As far as web development trends are concerned, we see below area getting more interest:
As computers and mobile devices are becoming faster, the websites are becoming slower. It should be the other way around. The average page size keeps increasing.
As someone new to front-end development, I would advise you to think about the web performance from the beginning. A website that loads quickly and consumes fewer resources results in happier users and a lower carbon footprint. Let us all help build a more sustainable web!

We are excited about the release of Sematext Synthetics and its future road map. Thanks for having me and excellent work with SurviveJS!
Thanks for the interview, Siva! If you haven't already, adding a monitoring solution to your toolkit is a valuable asset for a web developer as that will allow you to put the effort where it matters and understand when things go wrong in a way you might not expect.
Sematext offers a free 30-day trial. Give it a go and send Siva your feedback!
