Application Performance Monitoring – Tools and Best Practices

In this information technology era, people rely heavily on various software applications to make their lives easier. Many new applications are launched every day, increasing the competition in the market.

You may find thousands of applications for a single task. However, the success of an application heavily depends on its performance.

Therefore, it’s essential to keep track of how an application performs regularly.

What is Application Performance Monitoring?

Application performance monitoring (APM) is continuously monitoring the performance of software applications to ensure they meet the required performance standards. APM helps businesses track key performance metrics of their applications using different monitoring tools and identify any performance issues affecting app performance.

Nowadays, application performance management has become increasingly complex with emerging application architectures like SaaS, PaaS, and IaaS, high usage of microservices and functions, and modern development practices like agile and DevOps. This complex and dynamic nature of software applications is one of the primary reasons behind the popularity of the APM market.


Why is it Worth it to Monitor Application Performance?

Application performance monitoring allows you to have an accurate view of what’s going on with your application as a whole. It also provides you with scores that your application obtains against different metrics. Those scores help to measure your application performance along different grounds.

Metrics such as response times, request rates, CPU and memory usage, server load, application throughput, and server health allow organizations to understand what contributes to the performance or failures of their applications.

Furthermore, these metrics bring clarity and help discover various performance bottlenecks, bloats, memory leaks, unnecessary execution cycles, and slow database queries in your application.

Some APM tools like ScoutAPM even track the root cause of these issues up to the specific code line. Thus, it saves the time developers spend on debugging.

This way, application performance monitoring brings numerous benefits to application owners such as helping resolve performance problems faster, avoiding interruptions, boosting performance, increasing conversion rates, and ultimately offering a great end-user experience.

The specific metrics you should monitor depend on the type of application. The above are the most popular in typical applications.


5 Best Practices for Application Performance Monitoring

1. Ensure that you have selected the right monitoring tools tailored to your needs

There are several aspects you need to consider before choosing an application performance monitoring tool. You should analyze your application requirements, customers, and service level agreements (SLAs). Moreover, you have to consider some factors related to the tool, such as its features, cost, supported programming languages, flexibility, ease of use, technical support, and integration with other tools and services.

Some APM tools will target monitoring minimal yet critical functionalities, while others may surpass your expectations by offering an extensive feature set. So, having a clear understanding of what you expect from these APM tools will help you make the right decision regarding selecting tools.

2. Set proper metrics for monitoring

Application performance management may seem overwhelming with the abundance of available data. Therefore, it is vital to focus on proper metrics for a successful monitoring process. Following are some critical metrics that are helpful for identifying application performance issues.

  • CPU usage – Monitor CPU usage to evaluate its effect on performance.
  • Error rates – Track how often the app performance fails or degrades.
  • Uptime – Track the availability of the application to verify the overall reliability and compliance with service level agreements.
  • Response times – Check if the speed is affecting the performance of the application by measuring the average response time.
  • Request Rates – Monitor the traffic for your application for spikes in traffic, inactivity, and the active number of users.
  • The number of app instances – Monitor the number of app or server instances running simultaneously. You can scale your app with auto-scaling to meet the actual user demand based on that number.
  • User experience – You can measure customer satisfaction or tolerance using a combination of SLA thresholds and Apdex scores. Thereby you can understand and improve the user experience.


3. Set up custom alerts and Notifications

Applications may differ in various aspects. Thus, you might need to set up your own custom alerts and notifications based on your requirements. When performance issues arise, team members should be notified about them and understand their impact before the end-user notices anything. APM tools enable you to create custom alert tools by defining thresholds on different metrics such as application response time, error rates, and ApDex score.

In addition to email notifications, some APM solutions even allow you to integrate these notifications with communication platforms like Slack. It helps IT teams to stay updated about performance issues and collaborate easily.

4. Periodically, manually analyze basic and advanced metrics and make conclusions

It is a good practice to manually assess some basic and advanced metrics periodically, rather than solely depending on APM tools. It will help you make some informed decisions regarding the applications that will positively impact your business outcomes.

5. Have a dedicated, responsible person for performance monitoring

You need to make some configurations to APM tools to properly utilize the numerous features they offer. Besides, you will need some hands-on experience and knowledge of the best practices to follow in order to get the most out of these tools. So it would be a wise idea to train an individual on your team on operating these tools and have a dedicated person responsible for performance monitoring.


Developing advanced applications we know how crucial aspect is performance. We advise our customers to plan performance monitoring and optimization matters from the very beginning. Thanks to that, the architecture and used technologies are closely matched to the future needs and scaling of the apps. As it usually happens – it is better to anticipate than to react to later events. Paul Jackowski CEO, ASPER BROTHERS Contact Me
