Why is Monitoring Your Application Important?

Why is Monitoring Your Application Important

Scott Pickard UPDATED: January 25, 2024

Outages of any kind can cause significant issues for a business; costs could be incurred in the form of potential lost customers, the mitigation of any issues, lost transaction data, and customer support for the aftermath; the costs can quickly add up from even a single outage, and aren’t always obvious when looking at just the numbers. But while outages are obvious, server infrastructure can suffer from more than just blackouts—brownouts, and performance degradations that often go unnoticed by the hosts but are noticed by end users, and can be just as costly in the long run.

Maintaining consistent performance on your network is critical to keeping customers. Think of it like a restaurant: if customers aren’t able to get a table, or if their meal takes too long to serve, it doesn’t matter how good the food is, as it will be marred by the frustrations caused by the service that was delivered. In this example, while you’re going to get a sale out of this one visit, they’re less likely to come to the restaurant in the future. Performance leads to retention.

Depending on your infrastructure, performance issues, and black/brownouts will also undoubtedly affect the productivity of your internal users too. While retention isn’t a concern, according to a recent OnePoll study, employees waste 44 minutes each week on average because of slow network performance and connectivity.

These issues are especially true of your application infrastructure since this is typically what your end users are interacting with directly. Poor application performance also often goes unnoticed, since it is often monitored as part of the larger network infrastructure, instead of being monitored independently. This means that the data being monitored doesn’t always tell the full picture.

Performance Metrics

So distinguishing between Application Performance Monitoring (APM) and regular Network Performance Monitoring (NPM) is important because the data sets are innately but subtly different—but how are they different?

To provide visibility into the performance of the application components, APM is carried out by delving deeply into the application itself and its live code. They could be on a single machine or widely spread, and more sophisticated technologies will perform end-to-end transaction tracing. Ultimately, NPM prioritizes the focus on the conditions of the hardware, while APM is instead focused strictly on the related software.

The most important metrics that your application monitoring should focus on are average response time; error rates; request rate; application and server CPU and memory; and application availability. Some app languages such as Java also use something called Garbage Collection, which is the process of cleaning up memory usage in your applications; which is also the kind of thing you should prioritize monitoring as part of your APM.

Apdex is another important performance metric to track that is unique to application performance monitoring. It is a decimal score that ranges between 0 and 1, and it serves as an abstract indication of your end user’s overall experience, namely relating to the ability to access your services smoothly, quickly, and consistently.

Security Risks

Monitoring your applications goes beyond merely ensuring solid performance—it is also vital to the security of your network infrastructure. Most hacks and exploits will take advantage of your application software, meaning these kinds of vulnerabilities aren’t always detected as part of traditional network monitoring. But anomalous readings generated as part of your software metrics are straightforward for software-focused APM solutions to identify.

This is especially important when using third-party applications since vulnerabilities are more likely to be found and exploited in broadly used applications. You are still responsible for ensuring the safety of your application data even when the code was created by a different organization.

By analyzing transaction data, anomalous readings, usage spikes, and other metrics; you can quickly identify where malicious access is affecting your network. There is even a whole branch of monitoring called Application Security Monitoring (ASM) that sits alongside APM as an important part of your monitoring duties.

How to Monitor your Applications

So how do you go about monitoring your application data? Well, this is where application monitoring tools come into play. Application monitoring tools fulfill the requirements for accurate APM and ASM in the same way that network monitoring tools provide accurate data on your hardware. There’s a lot of overlap between these kinds of tools, and some of the best network monitors on the market also handle application monitoring either as part of their core lineup or as side products that can be expanded into your network.

These tools integrate with your applications on a software level, analyzing the infrastructure on a code level, using plugins and logging metrics. When determining which application monitoring tool to choose, the available integrations are often the deciding factor, since you need to ensure that all of your applications are compatible with the tool you’re using.

If you are using third-party applications that aren’t compatible with a certain tool, or you use bespoke or in-house-produced applications, then this is where APIs come into play. You’ll need to have the capabilities and know-how within your team to handle the development of API integration with your products, but many application monitors come with an API to ensure you can integrate with their solution.

The Leading Application Monitoring Tools

When it comes to finding an application monitoring tool, we have you covered with three excellent recommendations from three of the best application monitoring tools on the market. Each of these tools boasts scalable, widely integratable solutions that are perfect for your monitoring requirements. Ensure that you look through our full run-throughs of each of the products below to determine which is the best product for you.

If you’re struggling to decide what to even look for in an application monitoring tool, then note that there are a few key components to keep in mind. As mentioned above, one of the most important options is the available integrations—if the solution can’t handle your applications, it’s probably not the one for you. All three of the solutions we have listed below also include rigorously documented APIs.

It’s also important to distinguish application monitoring from the often confused application performance management—since ‘APM’ is an acronym used for both, they’re often conflated with one another, but this doesn’t really matter too much, since they both ultimately do similar things. Just note that managing your application data through things like load balancing, is also presented as a feature of a number of these application monitoring tools.
