There's a vast number of applications in the world. However, only a small percentage of apps meet the needs of users. Those pieces of software that satisfy users are the ones who win the game in the world of the software industry. Application Performance Monitoring (APM) is the collection of tools that professionals use to optimize and monitor the performance of apps.

What is APM Or Application Performance Monitoring

What is APM? APM is an industry jargon that involves anything to do with managing or monitoring your code, transaction times, application dependencies, and overall user experience. One can divide application performance monitoring tools broadly into three types, and they are:

App Metrics Based: Plenty of tools in the market use numerous server and app metrics and then name it APM. These tools are only capable of showing the number of requests your app receives and displays any URL that might be slow. However, they can't identify the root cause of the problem.

Code Level Performance: These tools rely on code profiling and transaction tracing for improving app performance.

Network-Based: The network-based tools or NPM are used to measure the performance of apps based on network traffic volume.

Components Of APM

Developers can exercise caution by avoiding common mistakes related to minimizing lags in applications. That said, even experienced developers can't build a perfect app. It's the reason why application performance monitoring is essential.

You need to monitor the performance of apps based on various factors, which is why application performing monitoring has different components. Here are the different parts of APM:

Runtime Application Architecture

In this part of application monitoring, the tool checks related hardware and software components during an application's execution. IT professionals can identify problems via pattern recognition.

Furthermore, it also helps in anticipating future issues.

Real User Monitoring

Another term for real user monitoring is the end-user experience. It's a process of collecting user-based performance data to know how well the application serves the users. It helps in finding out potential performance issues.

Real user monitoring enables organizations to respond to flaws of applications quickly and understand their impact.

Business Transactions

Business transactions aim to examine specific user interactions and repurpose them for testing and understanding conditions to identify performance problems. One can also call it user-defined transaction profiling. By running this test, organizations can trace events while it comes across different app's components.

Moreover, you can also find out when and where events occur to find out whether performance efficiency is optimized.

Component Monitoring

Component Monitoring involves the deep-diving of each application component. In this test, you include tracking every element of the IT infrastructure. The test covers extensive and in-depth monitoring of all used resources and experienced events within the infrastructure. It comprises all servers, middleware, operating systems, application components, and network components.

With component monitoring, you get a more in-depth understanding of how various IT infrastructure elements work together.

Analytics and Reporting

The final component of application performance monitoring is analytics and reporting. In this part, the system collects all the information that it gets from its previous components. It helps organizations in setting standards based on historical data. You can also find out the potential areas of applications that you can improve.

With smart usage of analytics and reporting, you can tremendously boost your organization's return on investment, and it also ensures that you're continually improving your product.

Application Performance Monitoring

What Should You Look For In Application Performance Monitoring Tool?

Selecting the best vendor for application monitoring tools is crucial. Here are some features you need to seek out in APM:

Support For A Wide Range Of Apps

Your business will be working with a variety of pieces of software. And your APM must evaluate each application based on your organization's needs. For instance, your APM shouldn't only monitor your web server, but also your network and custom-built applications.

Single Console For Monitoring

It's not pleasant to switch tools for measuring and optimizing application performance. Your APM should ensure all-round monitoring, alerting, and reporting.


ADDM stands for Application Discovery and Dependency Mapping. It's one of the most desired features in APM. What this means is your APM should be capable of discovering every application and server within your network.

Moreover, your APM tool must also categorize applications (servers, database, etc.), enabling users to visualize application interdependencies. Having this feature will help you save a lot of time for your organization.

Key Performance Indicators

Your application monitoring tool must present key performance indicators regularly. The key performance indicators mean metrics, such as response time, CPU usage, requests per minute, error states, etc.

Code Level Insights

There are network application performance management tools that will offer you insights into the source code. It will help you discover problems that might go unseen. You can take snapshots of individual transactions and identify codes that result in slower app performance. A DevOps team can benefit a lot from this detailed insight.

Alerts And Automated Actions

Alerts can save you a lot of time. APM tool should allow alert thresholds to users for configuring individual metrics and applications. It will let you find issues quickly. However, these alerts must also be able to process pre-configured actions for quicker troubleshooting. Some of the examples of automated activities can be notifications (email, SMS), generating thread dump/Garbage collection, implementing an MBean operation, etc.

Cost And Scalability

It's essential to see how your APM tool allows you to scale based on cost. You should see the increment in price while you enlarge your organization. Ensure your budget is enough to fit the cost of scaling.


Reports allow you to analyze and share insights regarding the app performance. These reports can help identify underutilized and overutilized servers, understand APM trends, predict future trends, and so on.

Final Thoughts

The advancement of information technology has made users more demanding than ever. It's essential to monitor your applications to ensure that you keep your customers intact. The only way to keep your customer happy is via application performance monitoring.

Application Performance Monitoring (APM) tools are not only meant for huge IT giants now. You can also choose a plan that is suitable for your organizational needs.
