Automating Shared Infrastructure Impact Analysis: Why Monitoring Backend Jobs is as important as monitoring applications

This posting illustrates how to effectively automate shared infrastructure analysis to support both your back-end jobs and your applications. Last week Gerald, one of our Dynatrace AppMon super users, sent me a PurePath as part of my Share Your PurePath program. He wanted to get my opinion on high I/O time they sporadically see in some of their key transactions on their Adobe-based documentation management system. The hotspot he tried to … read more

Using the Dynatrace DevOps Pipeline State UFO

The Dynatrace DevOps Pipeline State UFO was built out of the necessity to visualize alerts, problems, health and CI/CD pipeline state within the Dynatrace R&D organization. It sparked a cultural transformation as it made code quality that we pushed more frequently through our Delivery Pipeline more visible. You should read the background story from our Chief Software Architect Helmut Spiegl who invented the first versions of the UFO. We officially … read more

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

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

Scaling DevOps Deployments with AWS CodePipeline & Dynatrace

AWS CodePipeline is a more recent addition to Amazon Web Services – allowing development teams to push code changes from source check-in all the way into production in a very automated way. While code pipelines like that are not new (e.g: XebiaLabs, Electric Cloud, Jenkins Pipeline), Amazon provides seamless integration options for AWS CodeCommit, S3, CodeDeploy, Elastic Beanstalk, Cloud Formation as well as integration options for popular external DevOps tools … read more

From 0 To DevOps in 80 Days: The Dynatrace Transformation Story!

Market disruption can spark innovation and radical change, and DevOps — as a set of best practices — has emerged from software industry disruptions. Why? Because, over the years, delivering software in many organizations has become harder, slower and more error prone. Outdated technology became a disadvantage for older, established companies competing against startups without years of accumulated technical debt. Rigid processes and an old fashioned mindset blinded these enterprises to new business models … read more

Transformation to Continuous Innovation and Optimization

Businesses have always had to transform to find better and more efficient ways to deliver value faster to their users, customers or consumers. The motivating factors are shorter lead times, automated and streamlined value flow, as well as reduction of overall costs and bound capital, requiring enterprises to transition to a continuous innovation and optimization model. Prominent examples can be found when studying the last decades in the automobile industry with Toyota and … read more

Analyzing DNS Outage Impact on 3rd party Applications

Many blog posts have been written about the Dyn DNS DDOS attack  on October 21st. Dyn itself was very open with the problem and kept updating their customers and users impacted by the attack through their blog and twitter feed. My colleague David Jones (aka Jonesy) blogged about how our Dynatrace Synthetic monitoring picked up the problem for our customers. Here is a screenshot showing how, for instance, product downloads were … read more

Get Ready for DevOps: Remove Code & Architectural Bottlenecks

I was honored to do a DevOps Handbook Lessons Learned webinar with the DevOps “Godfather” Gene Kim earlier this month. In preparation for it I not only started reading his new DevOps Handbook, but also revisited the main messages of his previous DevOps book – The Phoenix Project. Gene (and co-authors) talk about the three ways which represent a maturity path of organizations from a rigid, slow and manual value chain, towards … read more
