What is Application Performance Monitoring (APM) Software?

Application performance monitoring (APM) software allows users to consistently track performance metrics for mobile, web-based, and desktop applications in real time. These metrics can be displayed as reports or on a visual dashboard. Baseline performance metrics can be customized to meet the minimum requirements of maintaining uptime and performance of applications. APM software helps identify failures or slowdowns within the overall application topology (the way all components supporting an application are connected). When applications are only as strong as their weakest topological component, identifying and bolstering that component is paramount to optimal function. Root-cause analysis (RCA)—the process of determining and fixing the underlying cause of an issue—becomes simpler when APM software reveals the exact failure points, which yields a quicker return to normal function. End-to-end visibility is another vital component of APM software. Solutions should be able to track full transactions regardless of where components are hosted, so buyers should consider infrastructure needs on this front. Smaller companies generally require only a few servers and databases, and therefore relatively small-scale monitoring and shorter transactions. Conversely, larger enterprise companies tend to have numerous, complex production environments, vast databases, and longer transactional chains. These larger companies require a high volume of virtual servers and services to perform all these tasks efficiently. More powerful APM solutions are designed to scan and monitor on a greater scale. Scalability should be an important consideration when choosing an APM solution. Whether a company’s requirements are vast or small, an APM solution exists to meet the buyer’s needs. Basic solutions are better suited for monitoring one or a few applications, but should a large number of applications need monitoring, companies should consider APM software that can scale while maintaining high performance. Companies planning on developing while growing should especially consider scalable APM software that can keep up with expanding infrastructure needs. What Types of Application Performance Monitoring (APM) Software Exist? Modular APM solutions Modular APM products—sold function by function, as opposed to as a full package—allow buyers to select exactly the functionalities necessary for their company when purchasing, such as database analysis, web transaction trailing, or network forensics. This is highly beneficial to smaller companies that might not need extensive features. For growing companies, modular APM solutions are particularly beneficial, as new features can be added piecemeal during the growth process. All-in-one APM solutions All-in-one solutions, by contrast, tend to be more beneficial for larger companies, as all the features are available in one package. All-in-one APM solutions tend to be feature-heavy and can be expensive, so acquiring a solution that overperforms might lead to fiscal waste. Open-source APM solutions Open-source products often have a lower price point than proprietary software and may even be free. These options may be better for smaller businesses that do not need expansive, feature-rich products. Most open-source products have small or no support staff behind them, so buyers should make sure that they have a good in-house development team when implementing one. Proprietary APM solutions Proprietary software, while more expensive than open-source software, is often more powerful and robust in its performance. These products tend to have stronger, larger support structures in place for implementation and long-term use. Buyers should be cautious that they don’t spend more for a brand name than the functions they need when selecting a proprietary solution.

What are the Common Features of Application Performance Monitoring (APM) Software?

The following are some core features within APM software that can help users interpret data, manage key alerts, and more: Metric dashboard: A metric dashboard is an easily digestible, graphical representation of current functionality data. This can include response time meters, use load charting, or other key data. Alerting: APM software’s alerting features give users an immediate warning when performance dips below baselines. The software can email teams automatically, show heads-up desktop notifications, or even automate text notifications to key engineers and management. Comprehensive tracking: Comprehensive tracking refers to the ability to follow all applications, regardless of where they are hosted. Users can optimize hosting options without worrying about lost information by following their cloud application infrastructure in real time, side by side with their local infrastructure. Transaction and topology analysis: Transaction and topology analysis allows users to present details for every step of a transaction. With end-to-end visibility, there are no secrets about any application functionality at any step. Users can make informed decisions about optimizing functionality with comprehensive data.

What are the Benefits of Application Performance Monitoring (APM) Software?

Improve application performance: Nothing creates more technological headaches than applications that function suboptimally. APM solutions reduce the strain on a system with immediate alerts when performance dips below a certain threshold, allowing companies to address problems as they happen. Increase consumer satisfaction: A quick turnaround on functionality issues leads to happier consumers. APM solutions assist in identifying stress points and bottlenecks within application topology to focus on troubleshooting exactly where it is needed. Save money: Application downtime can be costly, both in the time lost to product or service provision and in the resources needed to resolve it. APM solutions help create an environment for applications to run optimally, thereby improving reliability and helping drive customer acquisition and retainment.
