As a result, the demand for producing high-performing applications is also increasing. And to produce a successful app that users can’t get over with, you need to ensure it performs efficiently without giving a hard time to users.
But how would you know that?
Is there a way to determine whether or not the users are happy with your app?
Yes, there is a way – by using Application Performance Monitoring (APM) software.
APM software plays a significant role in making sure the app performance is solid and meets user expectations. It can identify issues and notify you so you can make quick fixes and improve its performance.
In this article, we’ll dive deeper into what APM software is all about, its benefits, and the top open-source APM software to help you monitor, troubleshoot, and optimize your apps.
Let’s jump in!
What is APM Software?
Application performance monitoring (APM) software is a tool that can monitor and track an application’s performance to identify performance issues quickly and solve them.
An APM solution shows app performance metrics with insights such as the volume of transactions it processed, response times, request rates, error rates, application availability, and more.
The software displays all the metrics in different types of data visualizations in a clear dashboard to detect issues quickly before the users do. APM solutions are used mainly by app administrators and developers to manage applications, find out possible reasons for errors, and troubleshoot them to optimize the user experience.
Why Do You Need Application Monitoring Software?
If you deal with application development and deployment, APM software is a must-have for your organization regardless of its scale or type of project. It executes intensive monitoring, collects logs, and converts them into valuable insights to improve your app performance.
Here are some of the benefits of using APM software:
- Clearer visibility into applications: If you use a powerful APM tool and implement it well, it will provide clear visibility into the applications existing in your complete tech stack. It will highlight how they perform, where they are located, and what devices users use to access them. In this way, you can learn the bottlenecks and map user satisfaction to improve its performance.
- Meet customer expectations: Using APM software makes your organization more customer-centric and indicates that you care about the end-users. With high visibility, the more issues you can catch, the more improvements you can make to meet the user expectations and elevate your brand reputation.
- Better security: By identifying issues and improving them sooner, you are making your application stronger. In this way, your applications won’t be vulnerable enough to let hackers exploit them. As a result, you will make your app more secure and compliant with regulations while maintaining the end-user trust.
- Accelerate innovation: If you can reduce the time required to solve issues by monitoring apps using APM solutions, your team will get more time to spend on innovation. They can research and experiment with adding new functionalities rather than just fixing bugs or investigating the cause all the time.
- Manage IT costs: APM software helps manage your IT costs better as you can leverage its powerful insights to make informed decisions. It can predict how application usage varies and helps you manage your resources, including your IT infrastructure, tools, and employees. As a result of automation, you can also optimize your team’s efficiency and operating cost and boost ROI.
Apart from all these, APM software can also help enhance app development lifecycle, understand dependencies, audit code execution, monitor network performance, and more.
Now, when you search for APM software, you will get plenty of them, both free and paid. You may find many cloud APM; however, some open-source APM solutions are also fantastic and in no way lesser.
So, let’s look at some of the best open-source application performance monitoring (APM) tools to help you monitor your apps, find issues, and fix them to deliver the best possible user experience.

Metrics also tracks 1, 5, and 15-minute moving averages. Console Reporter lets you access reports which you will receive every second. The MetricRegistry class is the centerpiece used to store each application’s metrics, while Gauges are used to measure the value instantly. It helps in running the number of works in the queue.
Furthermore, Counters are also in the list that is similar to Gauge but used to increment and decrement the value. Metrics presents data in histograms that show the statistical distribution of the data and maximum, mean, minimum, etc. With the timer, you can measure the time needed to process a request.
The Metrics-health checks module is used to centralize service health, while the Metrics-JMX module is used as a dependency. Once started, you can see the registry via VisualVM and JConsole.
