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 …
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 …
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 …
Log management is a process of handling copious volumes of logs that are made up of several processes, such as log collection, log aggregation, storage, rotation, analysis, search, and reporting. Log aggregation, therefore, is a step in the overall management process in which you consolidate different log formats coming from different sources all into one place to make it easier …
In one of the previous posts, I showed you how to build a microservice with Java EE and JBoss Forge. But building one microservice is obviously not enough. The overall idea of this architectural style is to implement an application as a system of services. In the beginning, that seems like an easy task. As long as each service solves only …
At Stackify, we understand the amount of effort that goes into creating great applications. That’s why we build tools for Application Performance Management (APM), log management, and a whole suite of application support tools (in one solution) to make your life easier and your apps better. But every developer knows that the foundation of an outstanding application is its architecture. In …
Troubleshooting application problems are never fun. We would much rather be writing code on some cool new project. In this article, we will cover some tips on how to troubleshoot ASP.NET web applications. ASP.NET troubleshooting topics: Is Your Web Application Returning Lots of Errors? Entire application is slow Troubleshooting a specific web request Is Your Web Application Returning Lots of …
Application and server logs are the eyes and ears for most developers. Anytime there is a problem with software, the first thing developers want to see is the logs. Developers typically need access to multiple types of logs. Including logs directly from their application, but also logs from servers, web server access logs and more. Piecing this puzzle together across …
Because security is an increasing concern for developers, a new movement is emerging, known as DevSecOps, which encourages developers to bring security and standards to the forefront while building applications. That means there’s good reason to stay on top of security information and event management trends and best practices, as well as the solutions that support it. With that in mind, let’s …
Logback is a logging framework for Java applications, created as a successor to the popular log4j project. In fact, both of these frameworks were created by the same developer. Given that logging is a crucial part of any application for both debugging and audit purposes, choosing an adequate logging library is a foundational decision for any project. There are several …
The first thing every developer wants to see when their application isn’t working correctly is their logs. The only thing worse than not having any logging is not being able to access it quickly. How many times have you begged a system administrator or another developer to send you the log files? Talk about a huge waste of time! Log files …
Security Information and Event Management (SIEM) allows you to get real time analysis on threats and security alerts that are created by network applications and hardware. It controls the storage, manipulation, analysis, and reporting of different security data and enables you to correlate different events and alerts. SIEM plays a role in regulatory compliance and isn’t something that you should ignore. …
Syslog is a standard for sending and receiving notification messages–in a particular format–from various network devices. The messages include time stamps, event messages, severity, host IP addresses, diagnostics and more. In terms of its built-in severity level, it can communicate a range between level 0, an Emergency, level 5, a Warning, System Unstable, critical and level 6 and 7 which …
Log4j2 is the updated version of the popular and influential log4j library, used extensively throughout the Java ecosystem for so many years. Version 2.x keeps all the logging features of its predecessor and builds on that foundation with some significant improvements, especially in the area of performance. And of course, given how instrumental logging is for any application, both for …
Developing in .NET provides several powerful benefits, including less overall code, improved security, ease of updates/changes, and language independence. That said, the system isn’t without errors and problems. From common exceptions to coding mistakes to incorrect assumptions, most of these issues come down to programmer error. The list below shares the 50 top .NET software errors from around the web. …
Logging runtime information in your Java application is critically useful for understanding the behavior of any app, especially in cases when you encounter unexpected scenarios, errors or just need track certain application events. In a real-world production environment, you usually don’t have the luxury of debugging. And so, logging files can be the only thing you have to go off …
Gone are the days of painful plain-text log management. While plain-text data is still useful in certain situations, when it comes to doing extended analysis to gather insightful infrastructure data – and improve the quality of your code – it pays to invest in reliable log management tools and systems that can empower your business workflow. Logs are not an …
Microsoft’s IIS web server uses a non-standard file format that is rarely seen. IIS Log Files use a space-delimited file format and also contain comments in them. The column headings are defined in the comments. In this article, we are going to take a look at how to interpret IIS log files. By the way, if you need help finding your IIS log …
