In this digital era, the use of software has considerably simplified our business transactions and general experience. The user journey, on the other hand, isn’t always straightforward. Businesses must constantly monitor their software packages to ensure that they are performing as expected.

Any application’s success is dependent on its performance. As users rely on web applications to meet their daily demands, a company’s success is now proportional to the performance of its applications. As a result, for any company to provide and manage a top-notch user experience, Application Performance Monitoring (APM) is essential.

Application performance monitoring (APM) enables companies to measure the performance of software applications in order to discover and investigate problems that arise during development and execution. With the growth of SaaS apps and cloud-native infrastructure, application performance monitoring has become a critical tool for guaranteeing high-quality service for online and mobile apps.

APM metrics are strongly focused on performance, evaluating the number of transactions processed per second by the application and the cumulative response time for each of those transactions. APM can also be used to evaluate hardware performance problems that may result in obstacles and to test the efficiency of devices executing those transactions. APM tools, on the other hand, are specifically intended to precisely measure application performance on a detailed level, and depend on AI-driven insights to understand immediately any problematic infrastructure dependencies.

Organizations may make greater use of the data they currently have by detecting issues before they affect users, minimizing the recovery period when errors occur, responding faster and achieving service-level contracts with the help of an application performance monitoring tool (SLAs).

 

In this blog, we’ll go over the different sorts of structures and processes that APM monitors, the different types of metrics that APM tools provide and the essential characteristics to look for when selecting top-tier APM solutions for businesses.

1. What is Application Performance Monitoring (APM)?

The process of monitoring, maintaining, and keeping on top of an application’s performance is known as application performance monitoring (APM). The application’s technical performance, as well as its perceived performance by users, are both monitored by APM.

Since today’s apps run on a highly distributed infrastructure, all of their elements are constantly changing and extremely difficult to track. As a result, in order to debug and control an application’s performance more effectively, APM software must look at its important components.

2. What does APM track?

APM does not directly assess the network’s quality, but instead the performance of an application that runs on it. APM analyzes a web application’s transactional speed, as well as the pace at which separate services execute their parts of the transaction and other app performance data. While APM systems vary in terms of architecture and feature set, the basic purpose of APM is to gather all of the elements of every transaction produced by an application and its users, giving companies meaningful insights into every aspect of the application. APM can also detect and report on deviations that the application produces, allowing developers and site reliability engineers (SREs) to find and troubleshoot unexpected issues concealed inside the application design.

The goal of APM tools is to answer a few important questions such as:

• Is the application responding and functioning as it should?
• Is the application being hindered by performance bottlenecks or other errors?
• If that’s the case, what’s causing the bottleneck or error? Is it the application on its own?
• Is it the dependencies among the various services that make up the application? Is there an issue with the infrastructure?
• What impact does this bottleneck have on end-users and the company?
• Is it possible to eliminate this bottleneck?

3. What are the most important APM metrics?

APM tools often monitor three categories of metrics, which are referred to as RED metrics:

• Rate: The rate at which a transaction is completed is referred to as the rate.
• Inaccuracy: If any errors are produced.
• Total time: The amount of time it takes to complete a transaction.

APM is approached differently by different technologies, offering developers and SREs a better insight into application performance concerns. The following metrics are commonly collected by APM tools:

• Average reaction time: How quickly does the app reply to user requests and complete transactions, and how quickly is it slowing down?
• Entire user traffic/request rate: As the number of concurrent users grows, performance often suffers. APM solutions measure the progress of each transaction at a detailed level, allowing SREs and developers to determine the cause of performance issues.
• Rate of Errors: Does an application produce errors, and if so, how severe are they? What part of the application is causing these errors? This data can be used to speed up debugging and track the application’s overall reliability.
• Business KPIs and SLOs: Is the app achieving the needed business key performance indicators (KPIs), service level agreements (SLAs), and service-level objectives (SLOs), which may include aspects like checkout time, number of logins, and duration or frequency of downtime? Any deviations from your SLO error budget — the rate at which you can miss those goals could cost your company a lot of money.

4. What exactly is an APM solution?

An application performance monitoring (APM) solution is software that includes numerous critical application monitoring functions. These characteristics include:

4.1 Front-End Monitoring

Both real user monitoring (RUM) and artificial transaction monitoring are supported on the front. As client-side code like JavaScript frequently generates blind spots in the business customer experience, real user monitoring becomes even more critical, and artificial monitoring can effectively uncover vulnerabilities before code is deployed, real user monitoring becomes even more crucial.

4.2 Analytics

Developers, SREs, and entrepreneurs can use APM solutions to watch performance data over time in order to assess whether an application achieves its SLOs and keep track of processes as the conditions change. A spike in the number of users, a decline in service, or modifications to the source code are all examples of such changes. Artificial intelligence (AI) and machine learning techniques can then anticipate whether and why performance is likely to decline using root cause analysis and anomaly detection logic. Application logs can also be used and analyzed by APM technologies to produce insights and locate trouble regions.

4.3 Application discovery, tracing, and diagnostics (ADTD)

APM solutions identify and map all the microservices that make up an application, as well as web servers, application servers, application frameworks, and other platforms on the network including on-premises servers, cloud-based servers, and hybrid infrastructure systems. ADTD does this by combining bytecode instrumentation (BCI) which can dynamically profile applications, with distributed tracing approaches.

While APM solutions differ in terms of complexity, design, scope, and cost, it’s important to remember that the purpose of an APM solution is to provide developers and SREs with advanced analytics into not only application performance issues, but also the causes behind those issues. It’s not really beneficial to simply know that an application is slow or has issues. The most useful aspect of APM is that it allows teams to swiftly identify the core cause of slowdowns and errors. A good APM tool will visualize this data in the form of a dashboard that shows the performance of each service and its dependencies over time.

5. Advantages of Application Performance Monitoring (APM)

APM offers a number of obvious benefits to organizations that use these tools, including:

5.1 Increased profits

Customers may become dissatisfied and seek an alternative if an application or service is unavailable, affecting revenue. APM can assist you not only keep your applications up and running but can also speed up essential application loading times.

5.2 Service degradations and SLO breaches are reduced.

One of the main reasons organizations use APM is to swiftly troubleshoot problems and restore full functioning to systems in order to fulfil SLOs in the event of a problem, while also preventing future problems. APM is an important tool for minimizing mean time to resolution (MTTR) from application-related faults and performance concerns.

5.3 Effective digital experience and customer experience

The sooner your application responds, the pleased your clients will be. Customers’ judgments are influenced by latency, which is used as a determinant of performance in both desktop and mobile searches. You’re probably going to lose end-user consumers if you don’t evaluate mobile and web application performance on a regular basis.

5.4 Increased competitiveness and speed

APM ensures application optimization, allowing firms to stay up with the industry’s increased needs by enhancing speed and agility. Latency is on par with downtime in most businesses, thus the enhanced speed and agility give you a competitive advantage.

6. What is the difference between application performance monitoring and infrastructure monitoring?

Both application and infrastructure monitoring assist admins in identifying and resolving performance and productivity issues that might obstruct business operations. They may both compile user experience data and determine whether an IT system is meeting or falling short of performance targets, as well as whether bugs and other disruptions are present. Both monitoring systems, however, are approached differently.

As previously said, application performance monitoring examines how applications operate and whether they are functioning properly. If they aren’t, the monitoring tool gathers data on the cause of the problem and alerts IT personnel, allowing them to link the performance of a given application or set of applications to business or result metrics. It also enables them to detect and resolve performance issues on the backend before they significantly affect the end-user experience.

IT infrastructure monitoring, on the other hand, automates the collecting and analysis of data for numerous components of an organization’s computing environment. Once an issue has been detected, the infrastructure monitoring tool notifies IT personnel so that they may more quickly and effectively address the problem before it hinders or lowers productivity. Infrastructure monitoring also ensures that network resources are performing at their best and in accordance with their specifications.

8. How to Choose the Optimal APM Solution?

There are numerous APM solutions available, each with its own set of benefits and drawbacks. Below are some essential considerations to assist you to choose the proper APM solution for your organisation, bearing in mind that budget will also be an issue.

Questions to answer about your organisation:

• Are your apps made up of a single block of code that runs on a single virtual machine (VM), or do you use a microservices-based design?
• Is your company implementing a DevOps culture and employing current software development methodologies?
• Do you want to look for any anomalies and provide a wonderful experience to a wide range of users, or are you satisfied with only serving a small percentage of your clients well?
• How “real-time” do you need your insights to be?  Do you require alerts within seconds of an issue developing, or can you live with alerts that arrive after five minutes?

Look for the following characteristics:

• Support for applications created in a number of programming languages and deployed both on-premises and in cloud-based environments.
• Reporting and management are centralized, with an intuitive dashboard included.
• Code-level visibility into all apps, relevant services, and their dependencies throughout the entire stack (such as databases and external services).
