Lessons for Building and Monitoring Scalable ASP.NET Services!

Handling requests from Web Server (IIS) to Application Server (ASP.NET) can lead to performance and scalability issues. Often caused by misconfiguration — not scaling IIS and ASP.NET modules or custom code built without fully understanding what IIS & ASP.NET are executing behind the scenes — when handling requests. While this is not a new problem, it is a problem that software architects or lead developers often ignore. They ignore it … read more

Six mistakes in your OpenStack monitoring process…and how to fix them

Many cloud admins unwittingly sabotage their OpenStack monitoring processes. I collected a few common mistakes and what to do instead to make your OpenStack troubleshooting easier. Mistake #1: Investing a lot of time and effort into configuration Let’s get this straight: most commercial and open source monitoring tools avoid talking about how much effort you must invest in their configuration, let alone in their maintenance. So first try to find … read more

OpenStack monitoring beyond the Elastic Stack – Part 3: Monitoring with Dynatrace

This post is the third and final installment in our OpenStack monitoring series. Part 1 explores the state of OpenStack and some of its key terms, Part 2 is about the OpenStack monitoring space and how open source tools like the Elastic Stack (ELK Stack) compare to Dynatrace. In this last part let’s take a closer look at how Dynatrace monitors OpenStack. Since we started our journey with OpenStack, we … read more

OpenStack monitoring beyond the Elastic Stack – Part 2: Monitoring tool options

This article is the second part of our OpenStack monitoring series. Part 1 explores the state of OpenStack, and some of its key terms. In this post we will take a closer look at what your options are in case you want to set up a monitoring tool for OpenStack. The OpenStack monitoring space: Monasca, Ceilometer, Zabbix, Elastic Stack (ELK Stack) – and what they lack Monasca Monasca is the … read more

OpenStack monitoring beyond the Elastic Stack – Part 1: What is OpenStack?

We’ve been talking a lot about OpenStack over the past few months, and with good reason. Its explosive growth in popularity within the enterprise has enabled large, interoperable application architectures and, with this, a need for app-centric monitoring of the OpenStack cloud. There are several open source monitoring tools for OpenStack out there – like the Elastic Stack (ELK Stack) – but are they mature enough for the challenges posed by … read more

Dynatrace is first monitoring solution to provide full-stack insight into Cloud Foundry

Dynatrace support for Cloud Foundry applications has been available for some time now, helping application teams better understand and optimize their distributed microservices environments. As we work tirelessly to provide you with full insights into your technology stack, I’m happy to announce that Dynatrace is the first monitoring solution to provide full-stack insights into Cloud Foundry clusters — automatically and with no configuration. This includes monitoring of both Cloud Foundry cluster … read more

OpenStack Summit Boston Recap

The OpenStack Summit at the Hynes convention center earlier this month was a blast. Exciting keynotes where we heard that we’re in the age of 2nd generation private clouds, where everything is virtualized and the focus shifts on the applications again. That enables the OpenStack community also to engage with other OpenSource projects like Kubernetes or Cloud Foundry. On the second day there was a live interview with Edward Snowden, who … read more

Hybrid Cloud Problem Patterns: Chasing DNS Lookup Times from AWS EC2

As a performance architect, I get called into various production performance issues. One of our recent production issues happened on Tomcat AppServer running on an AWS EC2 instance in a VPC. VPC is joined with an on-premise DNS server. This service calls another micro service. When service went live, we noticed a high response time from a downstream micro service, and the downstream service logs did not show any performance … read more

Don’t just move your servers to the cloud

The cloud has now been around for a while and has transitioned from being a place where the cool kids play to an integral part of any companies IT and application strategy. The first and most obvious step is to handle compute power not within the own data center but rather the cloud. Spinning up a server in the cloud is just quicker and especially for very large corporations adding … read more

DockerCon 2017 – A Tale of Three Demos

DockerCon 2017 was three days of jam-packed action. As each day closed, I took some time to reflect with my colleagues on the hottest elements of our demos and discussions. We ended up with three solid demo videos covering key aspects of our solution for Docker environments. Auto-discovery and the power of Smartscape At previous employers, I’ve demonstrated a number of products, but I’ve never focused on the deployment of the … read more
