A Comparison of Top Application Performance Monitoring Tools

In the competitive business world, building a robust software application becomes a vital part of the business. Ensured application performance requires consistent monitoring across several aspects. However, building dedicated tools from scratch is time-consuming and likely unviable.

Several application performance monitoring (APM) tools are available to make it easier for development and operation teams. But before diving into that – what does an APM tool essentially do? Well, as the name suggests, it monitors the performance of your application – primarily by detecting issues, recognizing patterns, and providing insights that enable developers to focus on the most important aspects of their application. This makes sure that performance issues in your application don’t go unnoticed and can be worked upon to improve the overall customer experience.

This post will go through some of the top APM tools and compare them based on specific criteria. Here’s an outline of what we’ll be covering so you can easily navigate the guide:

Important Criteria for Evaluating APM tools

Each software application has a different kind of requirement and business problem to solve. For example, one application would want to focus on high availability, whereas another would like to scale well. Based on the application’s requirements, your monitoring preferences may vary.

When choosing or evaluating an APM tool, it is essential to consider multiple factors based on what you want to achieve. Below is a list of some of the most important aspects to consider for evaluating APM tools:

  1. Traceability & Root Cause Analysis.
  2. Data Granularity
  3. Security
  4. Ease of Use and Implementation
  5. Programming Language Support
  6. Tool Integrations

Let’s look at them in detail.

Traceability & Root cause Analysis

When an error occurs, the APM tool is supposed to effectively trace the location and cause of the error and send out corresponding alerts. Traceability is a crucial aspect of monitoring tools that can save a lot of time in debugging issues.

Performance Monitoring

Quantitative metrics that allow developers to benchmark their application’s performance play a key role in evaluating performance over time. Therefore, it is vital to look out for the most important metrics to our application before choosing an APM tool.

Here are some common yet essential metrics that APM tools can provide:


Data security is one of the most important aspects to consider when choosing an APM (or, for that matter, any software) tool. Monitoring tools should not only follow proper security standards and protocols to make sure that your application data is safe but also be able to effectively detect and alert about potential security anomalies or breaches in your application.

Ease of Use / Implementation

APM tools, like any other software application, should be user-friendly and easy to set up. The easier it is for teams to work their way around these tools (for example, through neat dashboard UI and UX, clean visualizations, graphs, data representations, etc.), the better their overall experience.

Programming Language Support

Another criterion by which we can evaluate APM tools is the number of programming languages that it supports. More language support allows developers to rest assured that if they were to switch to (or incorporate) another programming language in their stack, they could do it without worrying about setting up another APM tool from scratch.  

Technical Support

Technical support is an important aspect while choosing an APM tool. Depending on your APM tool, support is offered through chat, email, or phone. The more technical support developers have, the easier it is for them to navigate issues and challenges that might otherwise hinder action.


As the name suggests, this criterion represents how well the tool integrates with other applications and services. Easier integration with third-party tools can make the overall monitoring process much more flexible and effective. For example, think about integrating the APM tool with a messaging platform like Slack and configuring it, so your team receives a notification each time there is a performance bottleneck.

Top 9 APM tools out there

Now let's look at some of the best APM tools in the market and discuss them based on the criteria discussed above.

Scout APM

ScoutAPM is a leading-edge APM tool that focuses on helping developers identify and resolve performance issues with minimum effort.
