As exciting as it can be to write new features in your ASP.Net application, our users inevitably encounter failed requests. Do you know how to troubleshoot IIS or ASP.NET errors on your servers? It can be tempting to bag on your desk and problem your annoyance. However, Windows and ASP.NET provide several different logs where failed requests are logged. This …
.NET Profilers are a developer’s best friend when it comes to optimizing application performance. They are especially critical when doing low level CPU and memory optimizations. But did you know that there are three different types of profilers? Traditional .NET profilers that track process memory usage, time spent per line of code and frequency of method calls. Lightweight profilers or other …
Managing an application’s performance, and specifically keeping it in good condition, is one of the hardest challenges in software development. That’s true for virtually any programming language and platform. Java is no exception to this rule. But beyond that, Java also presents some unique challenges of its own. For instance, one of those challenges has to do with garbage collection. …
Being able to execute a SQL performance tuning is a vital skill for software teams that rely on relational databases. Vital isn’t the only adjective that we can apply to it, though. Rare also comes to mind, unfortunately. Many software professionals think that they can just leave all the RDBMS settings as they came by default. They’re wrong. Often, the …
The last decade has ushered in a golden era of software engineering. The rise of cloud computing freed companies from managing their own data centers and provided on-demand scaling. These services allow for provisioning servers on the fly using configuration and code. Treating that task as just another type of software development led to the advent of DevOps. Cloud computing and …
The shift to cloud computing and the DevOps revolution have fueled some important changes in the way we think about software development and monitoring. It has delivered huge benefits to the companies that have fully embraced the approach. In fact, the DevOps Research and Assessment (DORA) 2018 industry survey found a new small group of “elite” performers that are deploying code far more often …
Mean time to resolution (MTTR) is defined as the sum of the total amount of time that service was interrupted divided by the number of individual incidents. The unit of measurement is some quantity of time. Ideally, you can use minutes as the unit. total downtime / # of incidents That is, unless you blacked out the eastern seaboard for weeks! …
There are many things to praise about the Ruby language: adherence to the object orientation paradigm, simplicity, elegance, and powerful meta-programming capabilities. Unfortunately, performance isn’t top of mind when people think about the many qualities of the language. For years, people have been denouncing the Ruby programming language as slow. Is it? Sure, some people will spread a fair amount …
Small changes for big wins At Stackify, we have the privilege of talking with hundreds of companies that have similar software challenges. We found that the #1 challenge is to deliver more value, faster, and with higher quality… while controlling cost, headcount, and complexity. How do you squeeze more out of every delivery cycle with less? There are ways to …
Microsoft’s Application Insights provides a basic application performance monitoring solution for .NET applications. For some types of .NET projects, Visual Studio will automatically add it to your solution. In this article, we are going to cover how to disable Application Insights. Why disable Application Insights? When considering to remove a tool that helps with monitoring, it’s worth thinking why you …
Metrics are how we assess aspects of our business, applications, and infrastructure. They allow us to measure and report on key indicators, and we can then use that information for making decisions, or to adjust for improved performance, stability and overall quality. While collecting and analyzing metrics can be hard work, in many respects, the most challenging aspect of working …
In the real world, a lot of mission-critical business logic lives in background services. Buying something from an e-commerce website, like Amazon, kicks off a wide array of tasks that must be completed after you click to confirm your order. Monitoring the performance of your web applications is only part of the puzzle if you want to proactively ensure your …
The Choice: Security or Visibility Stackify was founded because we were frustrated that our development team didn’t have the tools that they needed. We used a variety of tools like Nagios and Splunk, but none of our developers had access to them. What’s worse, even if they did, the tools only told part of the story and presented a unique …
Overview Monitoring the metrics and runtime characteristics of an application server is essential to ensure the adequate functioning of the applications running on that server, as well as to prevent or resolve potential issues in a timely manner. As far as Java applications go, one of the most commonly used servers is Apache Tomcat, which will be the focus of …
More information is always a good thing—especially when it comes to application performance monitoring (APM). One way to gather more information for APM purposes is to leverage application information in addition to environment data. In-context information generated and logged by the application itself can be invaluable when trying to diagnose and resolve anomalies during an application’s lifecycle. This article explains …
It seems like everyone these days is writing cool ASP.NET web applications. However, we all know that a lot of the real work is still done behind the scenes in background services. Buying something on Amazon no doubt kicks off a waterfall of tasks that are done behind the scenes to fulfill a single order. Including verifying stock, shipping, contacting …
“Shift left” is a relatively new term that means activities and responsibilities are moving earlier in an application’s lifecycle (that is, moving left on the delivery chain). The shift left concept has been applied to practices like security and QA. But its usefulness is not limited to those processes. This article discusses three reasons why application performance monitoring (APM) can …
Internet Information Services (IIS) uses a pool of worker processes (w3wp) to run ASP.NET web applications on Windows servers, but dealing with them crashing is no fun. The good news is, we are here to help provide you with resources on how to isolate and solve these issues, including how to identify crashes, capture crash dumps, and interpret them. Stackify …
