Dynatrace news. Observability as a topic is becoming more important as applications are using microservice architectures and are deployed in Kubernetes environments. In a recent real-world use case , a team of application developers were relying on metrics and log data alone to diagnose memory issues and they had a hard time identifying the root-cause of the issue.

The behavior of the Windows scheduler changed significantly in Windows 10 2004, in a way that will break a few applications, and there appears to have been no announcement, and the documentation has not been updated. This isn’t the first time this has happened , but this change seems bigger than last time. The short version is that calls to timeBeginPeriod from one process now affect other processes less than they used to, but there is still an effect.

In the modern world, websites have turned out to be very crucial and every single company or business or even individuals own websites. The huge demands of commercial enterprises make it compulsory for every company to have a site or web app. The quality of the application or website plays a crucial role in how clients perceive the business and, in turn, how much trust they have in its services or products.

In my experiences of planning for testing in various environments, and across several teams and organizations, the value of that planning was never the document itself; rather, it was the thoughts and consideration of the activities, resources and potential risks and issues yet to be discovered. Thinking deeply about all of those things and writing them down, in whatever form the final document took, was the real value of the exercise.

According to a survey conducted on software test automation , 51% of organisations prefer to retrain existing staff in test automation skills. While there are still 49% that would like to hire them specially for test automation related tasks. Other findings from the same survey confirmed that organisations want to move to more of test automation and a minimum of manual testing.

Over the last several months we’ve been noticing that some of our customers were having trouble with the performance of some of their sagas. Invariably, the sagas that were at fault were examples of the scatter-gather pattern, and the ultimate culprit was contention at the storage level due to the optimistic concurrency strategy that was being used.

Dynatrace news. The challenge with ASP.NET Web Service Observability, Diagnostics and Performance Optimization is that most monitoring & diagnostic tools only provide global Service Level Indicators metrics (SLIs) such as response time, failure rate, and throughput, but not metrics for each individual service endpoint. The reason for this is because a classical ASP.NET SOAP Web Service (ASMX) exposes its individual endpoints through the same URL and using the SoapAction HTTP Header to determ

Application development has evolved, and therefore new needs have arisen when it comes to testing and new tools to deal with them. Let’s take a look! We have gone from having monolithic architectures to applications based on (micro) services. Why do I say (micro) services instead of microservices? Because although the literature talks about the evolution of development from monolithic applications to applications based on microservices, in reality, we often find ourselves with the integration of

Don’t let the tools you use overly-constrain your thinking. Use them as a starting point for design and discovery, and then bend them to your needs. Alberto Brandolini says that EventStorming is his pizza and you can add your own topping. Every tool you use is somebody’s pizza, and you should always look for opportunities to tweak the recipe and find something that tingles your modelling tastebuds.

Testers, in their day-to-day lives, have to do many types of tasks. And to enable them to do those tasks there are many tools in the market too. These tools usually specialize in helping the testers perform a certain task. Sometimes these tools can be used to completely automate the tasks while at other times these tools can make the tasks easier. In this article we will try to broadly categorize these tools.

Dynatrace news. Kubernetes at scale in the enterprise is complex. Systems are constantly changing, with pods existing only briefly to perform tasks before they’re terminated. In such circumstances, it’s challenging to investigate the reasons for unexpected behavior or traffic between pods. Dynatrace is the only Kubernetes monitoring solution that provides continuous automation and full-stack automated observability without changing code, container images, or deployments.

So when I discovered that you can now rent by the hour massive instances within Google Compute Cloud that support 224 virtual cores based on AMD EPYC 2 Rome processors, I had to jump at the opportunity to see what kind low hanging fruit might be out there. Low and behold I found it! The record for MySQL on a single server stands at 2.1M QPS without using Unix sockets , and 2.25M QPS with Unix sockets.
