This has led to the recent release of our new Lambda monitoring extension supporting Node.js, Java, and Python. This extension was built from scratch to take into account all we’ve learned and the special requirements for monitoring ephemeral, auto-scaling, micro VMs like AWS Lambda. A look under the hood of AWS Lambda.

During the implementation of the real-time visualization I presented in part three , I had an idea for another visualization; I wanted to visualize the number of detected problems globally, for a longer timeframe. I wanted to understand how I could tune Dynatrace’s problem detection, but to do that I needed to understand the situation first.

The shortest possible time to value offered by Dynatrace is one of the most important reasons that our customers select Dynatrace over other monitoring solutions available on the market. Dynatrace OneAgent offers unprecedented ease of deployment and activation of monitoring. It will definitely find its way there before the GA release.

To achieve this in a secure and efficient manner, a key requirement for any database monitoring and management software is to have robust access management features. Monitored data may contain sensitive data that needs to be protected, and label-based access control can be used to ensure that only authorized individuals can access that data.

More modern tools can provide runtime insights into certain platforms, like Kubernetes or containers, but are still limited in their ability to detect which libraries are actually used vs. those that are present, but unused.

This can make it difficult to draw sound performance-tuning conclusions.

This is a lot slower than the serial batch mode query (2523ms/2522ms), as expected. The second problem.
