Latest Articles from Application Performance Engineering
Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software developm...
Cloud-based application performance monitoring and management provider Stackify announces the launch of their APM+ (Application Performance Management) solution for Microsoft® ASP.NET, a cost-effective solution offering real-time, code-level insights for business-critical applications....
Security is one the more prominent of the application service categories, likely due to its high profile impact. After all, if security fails, we all hear about it. The entire Internet. Forever. So when one conducts a survey on the state of application delivery (which is implemented...
A well-oiled APM solution comes from correlating bottom-up monitoring (infrastructure monitoring) with insights from top-down monitoring (real-time application monitoring) all within the context of the end-user-experience (EUE). But from what angle should we be looking at APM as it rel...
Application Performance Management (APM) has been bred with all the right elements to give us the insights we need to see the health of our applications. Similar to your most trusted watch dog, it alerts us to anomalies when events occur, providing awareness to the environment that onl...
My favorite war room accusation is: “It’s always the network at fault!” Whether you’re the one taking the blame or the one pointing the finger likely has everything to do with which seat you occupy in that war room. I suppose that comes with the territory, because at the same time ther...
Transaction management is not just for technical geeks; it is very much a subject that ‘business suits’ should be focused on. But should it be seen as a business issue for technologists or a technology issue for business people? Or doesn’t it matter and should transaction management...
More and more Web sites and applications are being moved from Apache to nginx. While Apache is still the number one HTTP server with more than 60% on active Web sites, nginx has now taken over the 2nd place in the ranking and relegated Microsoft’s IIS to 3rd place. Among the top 10.000...
In Part 6, we dove into the Nagle algorithm – perhaps (or hopefully) something you’ll never see. In Part VII, we get back to “pure” network and TCP roots as we examine how the TCP receive window interacts with WAN links. Each node participating in a TCP connection advertises its avail...
In Part V, we discussed processing delays caused by “slow” client and server nodes. In Part VI, we’ll discuss the Nagle algorithm, a behavior that can have a devastating impact on performance and, in many ways, appear to be a processing delay. Beyond being important for (reasonably) a...
“Vote early and vote often.” Back in the 1920s and ’30s, when neither election technology nor oversight were as effective as they are today, and the likes of Al Capone were at work gaming the system, this phrase wasn’t a joke. It was a best practice. If you want guaranteed results, wh...
Implementing high performance in enterprise storage is a constant battle to find and eliminate the next system bottleneck. Normally this alternates between limits of the underlying media and the computational overhead of metadata management, but choosing the wrong approach to deduplica...
A look into ITIL's Continual Service Improvement (CSI) model and the Application Performance Management (APM) framework indicates they are both focused on improvement. If you’re thinking about how to build a sustainable APM solution and how it can be anchored into the IT culture, cons...
Have you seen this error message before “java.sql.Exception: ORA-00060: deadlock detected while waiting for resource”? This is caused when parallel updates require locks on either rows or tables in your database. I recently ran into this exception on an instance of an IBM eCommerce Se...
Maximum productivity can be achieved more efficiently through event correlation, system automation and predictive analysis. Making that a reality however, requires consideration on how to manage the integration touch points from multiple toolsets and openness to the intrinsic value tha...
Application Performance Management (APM) may be brought in to help resuscitate an application that has recently become lethargic or assist the team in rehabilitating an intrinsic codebase. Once the goal is attained however, the propensity to pigeonhole APM as a point solution is high. ...
Over the last three years, the number of IT decision makers who believe their business has more applications than it needs has increased from just over a third (34 percent) to nearly half (48 percent). Apps bloat is a huge problem. Especially when the apps are non-mission critical, or...
Convincing the astute executive who is cautious in not making an impetuous decision on an APM investment can prove to be challenging. Consider the amount of due diligence that is brought to bear in the decision making process. The wide array of APM technologies that need to be reviewed...
APM is entering into a period of intense competition of technology and strategy with a multiplicity of vendors and viewpoints. While the nomenclature used within its space has five distinct dimensions that elucidate its meaning, the very acronym of APM is in question: Application Perfo...
Far too often “the database” is blamed for impacting performance and scalability of applications. In many cases, however, it turns out that it’s not the database itself, but the way the database is accessed by the application. Common problem patterns are requesting too much data, ineff...
Compuware on Monday announced new innovations to the Compuware Workbench, a modern, intuitive Eclipse-based mainframe development environment. First released in 2010, the Workbench has evolved into a dynamic solution that's made application development, testing and tuning faster and mo...
Over the last three years, the market has been abuzz with the news that deduplication technology was going to change the economics of flash-based storage systems forever. In fact just recently, in his article War Between SSDs and HDDs Will Escalate Through 2016, industry analyst Ben Wo...
As e-commerce continues to widen its reach beyond the traditional browser onto connected devices – smartphones, tablets, laptops, etc. – ensuring that you are ready to handle peak season traffic has become a very important consideration for retailers. It is critical to plan appropriate...

The argument that system monitoring is just a nice to have, and not really a core requirement for operational readiness, dissipates quickly when a critical application goes down with no warning. Can event management help foster a curiosity for innovative possibilities to make applicat...
Performance is your website’s first impression to visitors. Almost 50% of users expect a web page to load within two seconds. The move from a shared server to a dedicated server can alleviate many of a website’s performance issues and improve overall revenue and user experience. Share...
At times, I can be a bit of a procrastinator. If there is no pressing need to clean out the garage this week, shop for holiday gifts, or do my taxes, I can easily be convinced to let it go until next week or next month. Inevitably, though, something happens that makes me wish I hadn’t ...
Recently, one of our customers, let’s call him PointInFact, had a very typical problem. After deploying a new version of its software, some user requests degraded horribly. Requests that should have taken half a second took up to a minute. Interestingly, the PointInFact team runs a mul...
By embracing End-User-Experience (EUE) measurements as a key vehicle for demonstrating productivity, you build trust with your constituents in a very tangible way. The translation of IT metrics into business meaning (value) is what APM is all about. The goal here is to simplify a comp...
There has been a lot of talk among vendors and industry experts in the last year about how APM fits in with the DevOps philosophy. There have been many claims that because a vendor is easy to install and use, it automatically make it a solution catered for a DevOps crowd. This can’t be...
If transaction times jump from less than one second to more than 60 seconds after a software upgrade, it is evident that there is a problem that needs investigation. This scenario was experienced by a customer with its time-tracking application. Our customer identified this performance...
