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

The Opposite of War Room Isn’t Peace Room

Last week, I was trying to come up with a term for the opposite of war room. Why? I made a note a few months ago while reading a Gartner paper extolling the virtues of wire data, specifically as applied to the modern data center’s availability and performance management disciplines. Among other insights, the authors recommend convening frequent war rooms “…to encourage cross-team exploration” of performance data. Since the term … read more

Where APM Agents Fear to Tread

How important is APM to your organization? Assuming you’re reading this in the 21st century (if not, come back to the future!), the answer is probably pretty important. Your applications are the business. The digital experiences of your customers depend on them, as does the productivity of your employees. And, according to a Gartner Survey on End-User Experience Monitoring, companies with between 1,000 and 10,000 employees have an average of … read more

WAN (sic) is it a good time to optimize?

As a Dynatrace Guardian Consultant for the past three years, I’m posted on long-term engagements that allow me to sink my teeth into interesting technical and business issues that are at the very core of the organization. In this instance, the question arose as to whether and when it was appropriate to optimize a WAN? Most recently I’ve been on a dedicated assignment with a large European pharmaceutical company. They have offices … read more

Wire Data: A 20-year history & a bright future

While the term “wire data” may be relatively new, the concept isn’t; probes and capture agents have been collecting and examining network traffic almost from the beginning of network time. The term has been used casually by many network analysts, is particularly popular with Wireshark users, and – in a very casual Google search – was referenced in vendor documentation as early as March 2012. In fact, wire data has … read more

Top APM Acquisition Criteria and Behavior – and a Key Inhibitor

Lately I’ve been looking at some APM-related trends – specifically APM Acquisition Criteria and Behavior — to determine, to some degree, what motivates an organization to purchase. I’ve also been reading blogs, reading between the lines of vendor messaging, and of course relying on analyst research; it is this last bit of (relatively) unbiased insight that I’ll emphasize here, using it as a framework to highlight a few key features … read more

Application Performance Analytics: A Network Framework

So, why a discussion around Application Performance Analytics? Well, there’s a lot of buzz in this industry around the topic of performance analytics – an informal subset of IT operations analytics (ITOA) – as a solution to the growing mountains of monitoring data and the increasing complexity of application and network architectures. At the same time, there exist many purpose-built performance analysis solutions. Many are domain-centric – server monitoring and … read more
