Businesses need to monitor their system performance and resolve technical issues rapidly. For example, slowdowns or errors within the ERP system can stop the whole company from functioning: orders can not be served, suppliers can not be paid etc.

Companies can use APM tools to prevent these issues. APM refers to application performance management or application performance monitoring. Since APM tools facilitate monitoring the availability and performance of systems, they can help detect problems and run root-cause analysis to enable quick resolution of these problems.

What is APM?

An application performance management (APM) software tracks the performance and availability of digital assets like applications and websites. It notifies users if there are problems related to these systems. These problems can be response time disruptions or load time delays that prevent users from accessing task-related applications correctly. APM can also foresee possible problems by detecting early warning signs that might presage future issues. Here is Wikipedia’s definition of APM:

Application performance management (APM) is the monitoring and management of performance and availability of software applications. APM strives to detect and diagnose complex application performance problems to maintain an expected level of service.

How does it work?

APM tools can integrate into your digital assets and monitor every action in real-time. Here is how an APM tool works step by step:

  1. Monitoring businesses apps if they behave normally
  2. If something is not healthy, notifying related IT teams about the problem
  3. Collecting and analyzing the data in the context of the impact on the business and detecting the source of the problem
  4. Adapting the application environment to fix similar issues before they impact the business

Above, you can find an example of an APM interface. APM monitors information on almost any metric that play a role in application availability. Although metrics might change according to business needs, here are some performance metrics that APM collects:

  • Response time
  • Error rate
  • CPU usage
  • Customer satisfaction
  • User experience
  • Number of instances
  • Request rates
  • Application availability/uptime
  • Garbage collection (GC)

Why is APM important now?

APM helps companies manage their increasingly complex operations due to an increase in number of applications and increased data per application.

As we explained in detail in our RPA article, number of applications are increasing rapidly. Forbes states that there were more than 2.8 million apps available for Android users and more than 2.2 million apps for iOS users in March 2017. This number is much higher today with global businesses managing multiple apps. A similar situation exists for other cloud and on-prem apps.

The amount of data created in each app is increasing rapidly. A sign of that is the increasing amount of time people spend in front of their desktops and other devices. For example, people were spending more than 3 hours on their mobile apps in 2019 which is increasing ~5% per year.

The increased number of applications and populated data increases the need for monitoring because businesses own more applications to run and more users to satisfy. With performance monitoring and root-cause analysis becoming vital, companies need APM tools to collect and process the increased amount of application data so they can detect performance issues in a timely manner.

What is the APM Conceptual Framework?

Gartner designed the APM Conceptual Framework for an overall understanding of a five-dimensional APM model. The framework outlines five dimensions and describes their potential benefits:

End-User Experience

Real-time monitoring helps businesses to gain insights for performance trending and predictive analysis. According to Gartner’s framework, this dimension provides at least 80% of the APM value in terms of application visibility for the business. We also agree that this is the most impactful dimension. There are numerous public examples of end-user experience issues causing significant financial and reputational damage. 

This dimension has two main components: passive and active. Passive monitoring is usually an agentless appliance that can be implement with limited operational risk using network port mirroring. On the other hand, active monitoring, also known as synthetic monitoring, consists of artificial bots that help report on system availability and predefined business transactions. You can also read more about synthetic monitoring in this article.

These components are good complements: When used together, they help provide visibility on application health during both peak and off-peak hours.

Runtime Application Architecture

This dimension is vital for automating the process of mapping transactions and applications to underlying infrastructure components. While APM tools can identify the dependency mappings automatically, expert knowledge can be used to further refine the results with an understanding of how network topologies interact with the application architecture. It becomes a critical component to build on while implementing an overall runtime architecture solution because it helps lay the foundation for event correlation and provides the basis for a general understanding of how network topologies interact with application architectures.

Business Transactions

Not all application performance can be measured by end-user experience. For example, there are automated B2B processes where companies commit to SLAs. APM solutions can be used to monitor such SLAs and track root causes for issues in SLA levels.

Deep Dive Component Monitoring (DDCM)

This component usually targets the web, application, and messaging servers of businesses. It provides real-time information about the J2EE and .NET stacks. A robust solution shows a clear path from code execution to the URL rendered, and finally to the user request. 

Analytics / Reporting

Standardization of application performance data is essential for businesses. While raw data from digital assets provides flexibility in reporting, it allows for answering a wide variety of performance questions as they arise. However, too much information can make analytics harder. Thus, it is vital for APM tools to be able to identify key issues and summarize findings.

What are its benefits?


  • helps prevent issues before affecting a large number of users by alerting administrators regarding abnormal application behavior.
  • reduces Mean Time to Resolution (MTTR) enabling faster issue resolution thanks to root cause analysis capabilities
  • reduces manual troubleshooting effort by identifying root causes. APM saves time for IT professionals since they no longer need to search through each event log to identify root causes

What are the main capabilities of APM?

APM collects and analyzes application data to track application availability and performance. It foresees or detects technical problems and aims to solve them quickly. Below are the main capabilities of APM:

Anomaly Detection

An APM software identifies abnormal issues and responds to them rapidly. These issues are detected when performance metrics don’t conform to the usual patterns. The duration of the identification process depends on the depth of data collected, sensitivity and accuracy of the algorithms.

Root Cause Analysis

By running root cause analysis, APM aims to determine the probable cause of the problem within the business system.

To run a root cause analysis, APM constructs a causality chain linking cause and effect. The probable cause is connected to the impacted applications. With this methodology, APM can focus on the cause of the problem.

Root cause analysis also enables identifying the impact of system changes. IT teams can calculate the potential impact of any planned changes in this way and take action accordingly.


APM tools can support analytics capabilities of an enterprise with their data collection capabilities. Businesses can leverage APM tools to monitor their key performance indicators (KPIs), including financial metrics. For example, shopping cart abandonment rates, shopping cart conversions, and even the financial value of a transaction are some of the KPIs that can be tracked for e-commerce companies.

Who are its potential users?

Application Monitoring by IT Operations Teams

IT operations teams are generally tasked with keeping the system infrastructure operating efficiently and smoothly. The most common use of APM in IT operations is to track application health and to identify application problems. APM can achieve this by monitoring application performance and send early-warning notifications of performance issues. Plus, it can run root cause analysis to understand the reasons of performance issues and avoid them happening again.

Application support teams need  They have a wide range of tasks, from root cause analysis to code development that holds the application and infrastructure together. Thus, APM tools play a critical role in tracking application performance and identify root causes if any problems occur.

DevOps Teams

DevOps teams need to detect and diagnose issues quickly, as well. They need to ensure their code quality and effectiveness for recent releases. While planning deployments and changes, running tests and measuring performance metrics are essential. APM tools can be used to assess the risks in planned deployments and help DevOps teams to evaluate the impact of planned application or infrastructure changes.

Application Owners or LOB (Line-of-Business) Managers

While IT teams generally inform application owners and LOB managers about performance metrics, the information is rarely in the right level of granularity to make business decisions. With APM tools, managers can benefit from detailed metrics and end-user experience data to detect trends to improve their decision making.

What are the alternatives to APM?

Without an APM solution, here are a few alternative solutions that might help companies to detect and solve their performance issues in case of abnormal application behavior.

Synthetic transactions

A synthetic transaction means a transaction is created to execute against business software for performance measuring. Depending on the complexity of the software, building a basic program that calls a service and validates the response can run synthetic transactions.

However, synthetic transactions only detect performance issues and can’t identify the cause of the problem. Plus, it might not distinguish between a real problem or a usual slowdown in the system. Feel free to read our article about synthetic monitoring for more details.

Manual monitoring

Companies can manually monitor their systems by tracking real-time performance. For that, they can add performance monitoring codes to their system and record performance metrics in the database.

The challenge with this option is how to gain insights about collected real-time performance metrics. Developers need to determine what the standard parameters are, how to identify performance issues and how to discover root causes. Besides, the performance monitoring code added to the system might reduce your system performance, and the code might also include bugs.

Wait for customers to call customer support

While this is the easiest option, this option would reduce customer satisfaction and have a longer response time to solve performance-related issues.
