Application Performance & Architectural Problems You Can Find in an Hour

A step-by-step guide

When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that show performance problems. We walk them through the different analysis options and add the findings to a final POC Presentation. In this blog I want to share some screenshots and findings of a typical Proof of Concept recently done in a heterogeneous .NET/Java Environment.

Out-of-the-Box Result Presentation
The screenshots are taken from the final POC Presentation that my colleague Francis pulled together after analyzing a one hour recorded dynaTrace Session with an Out-Of-The-Box dynaTrace Configuration.

4. Analyzing Database Activity

Analyze Database Activity per Transaction. Identify problems where SQL Statements are called multiple times with the same parameters

5. Identifying slow Remoting calls

Identify slow remoting calls including full call context and the ability to trace into the server-side implementation of this call

6. Analyzing hidden exceptions

dynaTrace captures exceptions including full call stack. Drilling to the actual PurePath (Trace) gives more input on the actual call context

Conclusion
As you can see – it is easy to get an overview of the performance hotspots. The typical problems that we always find are things like too many database statements, hidden exceptions or long-running remoting calls. Read my blog about the Top 10 Server-Side Performance Problems that we often find with our dynaTrace Installations.

With so much going on in this space you could be forgiven for thinking you were always working with yesterday’s technologies. So much change, so quickly. What do you do if you have to build a solution from the ground up that is expected to live in the field for at least 5-10 years? This is the challenge we faced when we looked to refresh our existing 10-year-old custom hardware stack to measure the fullness of trash cans and compactors.
The emerging Internet of Everything creates tremendous new opportunities for customer engagement and business model innovation. However, enterprises must overcome a number of critical challenges to bring these new solutions to market.

Cloud computing is being adopted in one form or another by 94% of enterprises today. Tens of billions of new devices are being connected to The Internet of Things. And Big Data is driving this bus. An exponential increase is expected in the amount of information being processed, managed, analyzed, and acted upon by enterprise IT. This amazing is not part of some distant future - it is happening today. One report shows a 650% increase in enterprise data by 2020. Other estimates are even higher....
Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

I wanted to gather all of my Internet of Things (IOT) blogs into a single blog (that I could later use with my University of San Francisco (USF) Big Data “MBA” course). However as I started to pull these blogs together, I realized that my IOT discussion lacked a vision; it lacked an end point towards which an organization could drive their IOT envisioning, proof of value, app dev, data engineering and data science efforts. And I think that the IOT end point is really quite simple…
Identity is in everything and customers are looking to their providers to ensure the security of their identities, transactions and data. With the increased reliance on cloud-based services, service providers must build security and trust into their offerings, adding value to customers and improving the user experience. Making identity, security and privacy easy for customers provides a unique advantage over the competition.
Is the ongoing quest for agility in the data center forcing you to evaluate how to be a part of infrastructure automation efforts? As organizations evolve toward bimodal IT operations, they are embracing new service delivery models and leveraging virtualization to increase infrastructure agility. Therefore, the network must evolve in parallel to become equally agile. Read this essential piece of Gartner research for recommendations on achieving greater agility.
