Business Innovation through APM Metrics-Driven DevOps

Innovating faster to meet end-user demand is one of the challenges addressed by DevOps. DevOps bridges the knowledge gap about the impact between business and application teams. Application teams have to better understand the impact they have on business with code or deployment changes. On the other hand, business wants to better understand the impact on current development commitments when they come up with new requirements and a tight schedule. The … read more

Detecting the N+1 Asynchronous Thread Problem Pattern

I’ve been offering my help in analyzing performance data for quite a while now. Most of the time when analyzing PurePaths, load testing outputs or production log files, I find very similar problem patterns. This fact inspired us to automate problem detection in Dynatrace AppMon 6.5. Even though I think we cover a big part of common patterns, I am always on the lookout for something new – something I … read more

Monitoring ASP.NET Core applications

One of the hot topics currently in the .NET community is CoreCLR and ASP.NET Core. As most probably you already know: Microsoft decided to create a cross platform, high performance version of ASP.NET, which they even open-sourced. What is ASP.NET Core? There are many great posts about the basics of ASP.NET Core, so in this post we do not talk about the programming model and the differences between ASP.NET Core … read more

Sitecore Performance Tips: What’s Geography Got to Do with It?

It’s not very often that data aligns perfectly to illustrate a topic. Typically, there are very clear trends among the outlying data points that clearly support the topic in question, but it’s rarely absolute. So, while researching Sitecore performance topics this week, I spotted data points that almost perfectly align to support the premise of Geographical Performance Variance in User Experience, that is, in layman’s terms, the further away the … read more

Tracing is the new Debugging in Distributed App Development

Debugging is the developer’s best friend when it comes to understanding how code really executes – especially when trying to figure out why the code is not behaving as expected. Debugging works exceptionally well in monolithic apps or in service-oriented apps when you know exactly to which service instance you need to attach your debugger. In modern application architectures that embrace micro-services which either run on your machine, in a … read more

Adding the ‘How’ to ‘What’ for Sitecore Helix Test Automation

Prologue Following the introduction of the Sitecore Helix framework at Sitecore Symposium 2016 in New Orleans, and after attending Sitecore User Groups where Helix has been discussed, I wanted to take this opportunity to share insights on how to achieve the automation aspects outlined in Helix. By adding Dynatrace AppMon into your DevOps Continuous Integration (CI) / Continuous Deployment (CD) processes, you automatically ensure the highest levels of quality, performance, … read more

Defending the Network: Flow vs. Wire Data

In recent months, at multiple customers, I’ve had the opportunity to observe shockingly similar problems that follow an unfortunately common scenario: There is a perceived site issue A war room or incident is started The network is quickly thrown under the bus Why? Because the complaints are only coming from one site; therefore, it MUST be a network issue This predicament results in the network team reeling backward as they scramble … read more

Why WAN optimization requires performance management

WAN optimization can only be as efficient as you let it be. Recently I’ve seen a good example that illustrates how, without diligent application performance management, multi-million WAN optimization investments can quickly turn into a lukewarm “implementation completed” outcome, to say the least. The challenge at one of our customers started in a typical way: a large company, with operations around the globe, facilitated by a large SAP ERP and … read more
