Meeting user experience demands across software development organizations has made application monitoring and performance a crucial business development strategy.

With software development tilting toward wide-scale automation in testing and deployment, several application performance monitoring tools are designed to help DevOps (development and operations) engineers and software testing teams monitor and track application performance.

Application performance monitoring tools help businesses remain on top of the situation when there are perceived bottlenecks in application performance. Unfortunately, there is a proliferation of these tools, making it more difficult for IT teams to select the best solution for their business.

What is an APM monitoring tool?

APM tools are solutions designed to aid in the monitoring, tracking and reporting of application performance metrics in order to help DevOps take necessary actions to ensure applications meet business and user demands. They are solutions designed to automate the process of application performance monitoring by ensuring parameters that provide insight into the state of the application are tracked and reported.

In other words, application monitoring tools are software solutions that can provide digital experience monitoring, application tracking and diagnostics to support IT business operations.

With application monitoring tools, it becomes easier for DevOps to figure out issues within their application through the performance report generated and displayed on the dashboard.

Core features of APM monitoring tools

These core capabilities should form the checklist for development team leaders, software engineers and software testers when selecting APM tools for their projects:

  • APM tools should be able to carry out impact and causative analysis of application performance to facilitate the resolution of issues in the application.
  • APM tools should be able to automate the integration of other third-party software to accommodate evolving infrastructure.
  • APM tools should be able to handle the end-to-end observability of transactional behavior in the application to reveal how these transactions affect user experience.
  • APM tools should be able to mount real-time and automatic discovery and mapping of application components for easy discovery and resolution of application bottlenecks.
  • APM tools should support cross-platform monitoring across mobile and desktop to access, track and report end-user experience.
  • APM tools should be able to provide insights into how new integrations in the application infrastructure affect performance indicators.

How does APM monitoring work?

APM tools are configured to observe how applications behave in operation and how the app performance affects business goals as well as to gather data that provides a detailed explanation of where issues exist in the app for easy resolution. This may seem like a long crawl around the application, but it’s not, as the tool automates these processes to save IT teams from manually searching for issues on event logs.

Application performance monitoring works by measuring different application key performance indicators (KPIs) to understand how the application performs in real time. All APM tools work by checking whether an application is performing optimally. This includes running an end-to-end assessment loop through key components of the application.

If an issue is detected during one of the checks, the tool alerts the team of the root cause of the problems. Then, it goes further to measure the impact against the key business performance metrics.

Some of the core metrics measured by application performance monitoring include:

  • CPU Usage: APM tools measure how an application uses CPU and memory capacity to determine if they affect application performance.
  • Request Rates: APM tools measure the volume of traffic an app receives to help reveal periods of inactivity and spikes in traffic.
  • Application Uptime: APM tools monitor an app’s availability to end users and alerts IT staff during periods of downtime.
  • Error Rates: This metric indicates how often an error can occur in the application. APM tools work by tracking how often an application fails during usage.
  • Response Times: The average response time (ART) is another metric APM tools measure to reveal how speed may affect the application performance.

Why businesses need APM

The importance of application performance in the present-day business landscape cannot be overemphasized. As the world is increasingly being driven by digital transformations, many businesses depend mainly on applications to meet the needs of their customers.

SEE: Research: Digital transformation initiatives focus on collaboration (TechRepublic Premium)

However, there are situations where these applications malfunction, leading to glitches in end-user performance. These glitches could include load time issues, delayed response time or app crashes. APM tools can help mitigate malfunctions altogether as well as provide quick resolution times if they do happen.

APM cuts off operational silos

Operational silos are business operations or units that cannot easily interact with one another. APM breaks down these silos by unifying visibility across the entire application infrastructure, making it easy for different teams to know what’s happening in the application.

APM makes it easy to meet end-user expectations

Nothing brings down a business like leaving a customer base frustrated. APM enables businesses to be on top of the situation when there are performance issues with the application. In some cases, APM tools can provide an alerting system to notify key team members when there is a potential issue.

APM helps businesses resolve issues faster

APM makes it easy to figure out where an issue is within an application, facilitating quick resolutions.

APM solutions connect app performance with business analytics

APM solutions provide analytics showing how application performance affects some business areas. With this analytics, businesses can easily focus on critical areas that require urgent attention.
