The power of observability The power of observability becomes visible when you combine signals and put it all together. Checks performed by Checkly can provide a piece of the puzzle that gives you a better view of what is happening. For example, suppose you have a load balancer failure that prevents traffic from reaching your application. A check with Checkly will fail and you will see a dip in your application metrics.

Updates from Checkly Based on my previous post I have been in contact with Checkly about two parts that were not working as expected. I have some updates on these topics today. Sending traces from Checkly to Tempo In the previous post I mentioned that the traces in my Grafana environment showed root span not yet received. The root span was not available. This requires Checkly to send these spans to my environment as well.

Checkly This week I came across Checkly, a code-first synthetic monitoring solution that can do API checks and browser checks using PlayWright. It would have saved me a lot of time if this had been around 8 years ago. At that time I was working on a project where we were doing some external checks with a vendor like Checkly, but it was all manual configuration in a web interface. And internally we had a checker tool running that did all sorts of internal checks, both HTTP checks and database checks.
