APM monitoring tools

While traditional application monitoring techniques have supported the software lifecycle for decades, automated APM tools have streamlined the practice and made it even more efficient.  

DevOps teams utilize automated APM tools to receive alerts and notifications more quickly, enabling them to resolve performance issues before they impact the end-user experience. Thus, these tools enhance the effectiveness of the entire application monitoring process.  

Before we dive into APM tools and some of the best APM tools available in the market, let’s understand what application performance monitoring is and how it benefits a business.  

Application Monitoring and Tracing 

The software development lifecycle has always included application monitoring as a component. Moreover, under application monitoring, a business monitors its entire application as a whole. This practice allows DevOps teams to track metrics and understand overall application availability and response time.   

While application monitoring has been a strong pillar of software development and deployment, the practice only monitors surface-level events of an application. Therefore, DevOps teams have adopted various other practices to complement application monitoring techniques. Tracing is one such practice.   

Tracing allows DevOps teams to track the data progression and also the program flow of an application. In addition, it offers insights into complex distributed software environments.   

The majority of DevOps teams employ application monitoring techniques and use tracing for a more granular understanding of the application performance, whenever an issue arises.  

Therefore, we will look at the benefits of application monitoring, and the tools used for such monitoring practice in the next sections of this blog.   

Application Monitoring Benefits:    

Application Performance Monitoring helps to identify and notify the exact failure point in an application, in real time. As a result, teams can respond immediately, they fix performance and stability issues, and restore services without delay or before any hindrance in user experience.  

Furthermore, application monitoring sets a standard for performance metrics and alerts teams when the performance varies. It does this in a way that is convenient for teams or administrators. It provides visual data for the performance metrics, thus, enabling users to better understand the data.   

Alaska Airlines wanted to gather insights that would help them bring costly performance issues down. So, Alaska Airlines went with the APM solution. It allowed the company to derive a holistic view of its ecosystem and also understand and target the root causes of issues. As a result, the company experienced a 60% reduction in outages, and MTTR went down from an hour to 10 mins.

Benefits Of Application Monitoring

Some other key benefits of application monitoring in DevOps are:   

  • It reduces downtime  
  • Facilitates better user experience (UX); APM ensures traffic continues to flow. It can further identify latency issues and map anomalies as well as other end-user performance indicators  
  • Facilitates faster Patching and Mean Time to Resolution (MTTR); tracks down the fault domain, thus, speeding up a business’s patch management process  
  • Enhances the productivity of the application  
  • Improves SEO and conversion rates  
  • Ensures compliance with government and SLA rules   
  • APM improves the overall security of the application by efficiently addressing performance bugs and closing security vulnerabilities, saving time, and utilizing fewer resources.  

Since application performance monitoring has extensive benefits, the practice has been in use for many decades. However, traditional application monitoring ways were not as efficient and fruit-bearing as the new ways that include the usage of tools.   

In the past, PING testing was traditionally employed for application performance monitoring, which posed challenges as it required running tests to identify performance bottlenecks or bugs. This limitation resulted in compromised application performance during off-hours, leading to inconvenience for businesses and users.

That’s why automated application monitoring tools came into existence, to give what the traditional ways lacked. APM tools modernized the way application monitoring is done, enhancing the efficiency and also productivity of the whole process and application as a whole.   

Some features make an application performance monitoring tool more effective. These essential and top features are:  

  • Ability to measure the performance of application transactions (request + response)  
  • The performance of application dependencies should be monitored for issues   
  • Ability to carry out profiling at the code-level   
  • Monitors server resource usage  
  • A centralized application logging dashboard  
  • Facilitate Real User Monitoring (RUM)  

These were some of the desired characteristics of an APM tool. These features allow a tool to efficiently monitor an application’s performance, thereby covering all the intended aspects.   

Let’s now look at the top application performance monitoring tools and help a business choose the one that best fits its needs.
