What Is End User Performance Monitoring?

End-user performance monitoring, often called end-user experience monitoring, is how users interact with your application. When you build and deploy an application, users start engaging with it in various ways, including:

These interactions give you valuable insights into their experience and how well your application meets their needs.

User Interaction Tracking

At its core, end-user performance monitoring involves tracking and analyzing these interactions. By understanding what users are doing and how they’re doing it, you can get a clear picture of how your application performs from their perspective. But it doesn’t stop there. 

This type of monitoring also looks at how well your application is delivered to the user. For instance, if your app takes too long to load or crashes frequently, it can negatively impact the user’s experience.

Why Does End User Performance Monitoring Matter?

AWS cites that 88% of us won’t return to a website after a bad user experience. Visitors will likely get frustrated and leave if your website is slow or buggy, hurting your business or brand. Browser monitoring allows you to catch issues before they become big problems, ensuring your site is always performing at its best. 

It’s like having a backstage crew working around the clock to ensure the show goes off without a hitch, keeping your audience happy and engaged.

How Can End User Performance Monitoring Improve My Application?

By gathering this data, you can pinpoint areas that need improvement, ensuring your application runs smoothly and provides a positive user experience. Whether fixing bugs, optimizing load times, or enhancing functionality, end-user performance monitoring helps you create a better, more efficient application that meets user expectations.  

Why Do You Need End User Performance Monitoring?

User experience is everything. End-user performance monitoring provides critical, actionable insights into how your application performs from the perspective of your users.  With this intelligence, you can identify which parts of your application are performing well and which parts aren’t.

Identify the Parts of the Application That Perform Well and Poorly

When you build an application, it’s common to have different parts based on your service. If you’re building an e-commerce website, you probably will have categories for:

  • Men
  • Women
  • Kids
  • Special offers, etc.

Design Performance Analysis

Through end-user performance monitoring, you can identify which parts of the website are more pleasing to the user. Another example would be if you have used different designs (colors, templates, widget shapes, etc.) in your application. 

End-user performance monitoring would help you understand which design gives the user a better experience.

Understanding the Performance of a New Feature

Knowing how well it works is essential if your application has been online for quite some time and you’ve added a new feature. End-user performance monitoring helps you analyze the performance of the newly added feature.

Identify Page Load Problems and Script Issues

When you get information on user experience, you will also find details regarding the time the page takes to load. This can help you identify and fix page load and other network issues. An application's load time is important in user experience because no user wants to keep looking at the loading icon for long.

End-user performance monitoring will also identify script issues that will help you fix navigation problems and any possible glitches in the application with respect to how it’s designed to perform under ideal conditions.

Decide Where to Invest More

Knowing the user’s experience will give you an idea of what the user does and doesn’t like. This will help you prioritize your plan and decide which part of the application to focus more on.

How Can End User Performance Monitoring Help Your Business?

End-user performance monitoring (EUM) is like having a backstage pass to see how your customers and employees interact with your digital platforms in real-time. It goes beyond just tracking if your website or app is up and running; it dives into how users experience your services from their end. This kind of insight is crucial because, in today’s world, a smooth user experience is directly tied to your business's success.

Imagine you’re running an online store. If your site is slow or glitchy, customers will likely leave before completing a purchase. EUM helps you catch these issues early by monitoring everything from load times to the actual performance of your web pages or applications as experienced by users.

Remote Performance Analysis

It’s especially important now, with more people working remotely, where performance can be affected by factors outside your control, like their internet connection or home Wi-Fi.

What’s excellent about EUM is that it doesn’t just focus on problems within your own network. It also considers the broader environment, including cloud services and external providers, giving you a complete picture of what your users are experiencing.

Business Value Analysis

This level of detail helps you fix issues faster and understand how your digital tools perform in real-world conditions. 

For businesses, this means happier customers, more productive employees, and better business outcomes. When you can monitor and improve the end-user experience, you’re not just keeping your systems running smoothly but also protecting your brand’s reputation and driving your business forward.

5 Common End User Performance Monitoring Methods

1. Real User Monitoring: Accurate Insights on Actual Users

Real User Monitoring (RUM) delivers precise data about how real users interact with your application. As the name implies, RUM tracks the actual performance of your application as experienced by your users, allowing you to gather the most reliable information about the end-user experience. 

Also known as passive monitoring, RUM collects user experience data directly from the user's browser or via the cloud. The most common way to capture real user data is by using JavaScript injections.

How Does This Work?

While building an application, you determine which parts of the application you want to capture data from and inject some JavaScript code to monitor user actions in that part of your application. When the user accesses your application, the JavaScript code will be triggered on specific user actions and capture the required data.

Real-World Accuracy

Because RUM tracks performance based on user actions, it provides the most accurate results. When you write a script to mimic user behavior, like synthetic monitoring, you might overlook a few user actions. Real user monitoring will cover those actions.

When you use real user monitoring, you don’t just capture information about the user activity. You can also capture information such as:

  • Page views
  • Browser versions
  • User location
  • Page load time

What About The Drawbacks? 

Implementing real user monitoring does not affect the application's operation. The main drawback is that the results are only reliable when there is a decent amount of traffic. If no or very few users are using the application, the results are insufficient to take action.

2. Synthetic Monitoring: Simulating User Actions

Synthetic monitoring, also known as active monitoring or proactive monitoring, involves using a robot to monitor the end-user experience. To use synthetic monitoring, you must write scripts to simulate the user’s actions in your application.

You might be wondering, “How would simulating help? If we need to monitor end-user behavior, then why would we use a robot to simulate user actions?”

Synthetic Testing Benefits

You don’t need a real user to analyze the performance of your application. You can write a script to do what a real user would do and see how your application behaves. So, when you use synthetic monitoring, you learn about the availability of your application and its performance. 

As a bonus, if you use synthetic monitoring, you can fix any issues found before making the application available to your real users.

3. Application Performance Monitoring: Tracking Apps to Improve the End User Experience

Application performance monitoring (APM) tracks IT services through the performance of:

  • Web applications
  • Mobile apps 
  • SaaS applications

APM Metrics

APM tools help track metrics like:

  • Error rates
  • Downtime
  • Response time

These metrics give service providers insights into application performance and availability and how quickly they troubleshoot issues as they occur.

4. Device-Based End User Monitoring: Tracking the User's Device Performance

Using a heavy application utilizes a lot of system resources, which in turn affects user experience. You can use device-based end-user monitoring to monitor the load your application is putting on the device being used by the user.

The user might be using one of various devices, including:

  • Laptops
  • Mobile phones
  • Tablets, etc

Resource Optimization

You can use a light code to check the resources being utilized by your application on the user’s device. This will help you optimize your application for different devices. When you optimize your application, it runs smoothly on the user’s system, improving the user’s experience.

5. Business Activity Monitoring: Tracking Performance to Improve Applications and Ensure End User Satisfaction

Business activity monitoring (BAM) involves tracking critical business processes in real-time to gain insights into organizational performance and health. It encompasses collecting, analyzing, and presenting data related to various business activities, enabling stakeholders to make informed decisions promptly.

BAM integrates data from diverse sources across an organization, including:

  • Enterprise applications
  • Databases
  • Sensors

Holistic Data Analysis

This holistic data aggregation provides a comprehensive view of ongoing activities, facilitating the identification of bottlenecks and inefficiencies. By monitoring these activities in real-time or near real-time, BAM enables proactive intervention to address issues promptly and optimize processes for enhanced performance and productivity. 

Key types of business activity analytics that BAM can monitor include:

  • Process Governance: Monitoring adherence to defined processes and workflows to ensure consistency and efficiency. 
  • Compliance Monitoring: Tracking regulatory compliance and internal policy adherence to mitigate risks and ensure legal conformity. 
  • Process Completion Rates: Analyzing the rate and efficiency of completing business processes to improve operational effectiveness and resource allocation.

3 Common End User Performance Monitoring Metrics

1. What is Network Latency, and Why Does It Matter for Monitoring End User Performance?

Network latency refers to the time it takes for data to travel from one point to another across a network. EUEM tools monitor network latency to detect slow applications and improve end-user performance. 

High latency can cause frustrating delays for end users, damaging their experience and hurting business outcomes.

2. Application Downtime is the Enemy of Good End User Performance

Application downtime can occur for many reasons, including:

  • Network interruptions
  • Coding errors
  • Cloud vendor failures
  • Scheduled updates
  • Security breaches

No matter the cause, extended application downtime can negatively impact user experience (to say nothing of lost revenue and clients). The following are crucial to minimizing downtime:

  • Monitoring the mean time to detection (MMTD)
  • The time it takes to detect an issue
  • The mean time to, remediation (MTTR)
  • The amount of time it takes to troubleshoot an error once it is detected

3. Bandwidth and Throughput: What’s the Difference?

Bandwidth measures the volume of data that can pass through a network at any given time, an important metric when monitoring application performance. Unlike latency, which measures a system’s speed, bandwidth measures capacity. Organizations want to ensure their network can handle traffic and user activity, particularly during peak use.

Throughput Analysis

Understanding throughput is often even more valuable. While bandwidth measures possible capacity, throughput measures the average amount of data that passes through a network in a specific timeframe, considering the impact of latency. It reflects the number of data packets that arrive successfully and the amount of data packet loss. 

Monitoring tools can monitor network traffic and system storage, allowing IT teams to optimize systems and plan to keep applications running efficiently, even during peak traffic periods.
