Application Monitoring – Best Practices

UPDATED: September 10, 2025
To keep clients and ensure your business remains productive, your network must maintain consistent performance. Since your end users often engage directly with your application infrastructure, problems such as brownouts and overall performance degradation are particularly relevant to it. Poor application performance frequently goes unnoticed unless you properly integrate an application monitoring tool that can analyze your data traffic from a software level, and make rigorous observations into your live code.
But how should you approach application monitoring?
This article discusses some of the best practices that you should bear in mind when setting up an application monitoring suite. Make sure to read through these helpful tips thoroughly, and employ the tactics in your application monitoring. We’ve also included several application monitoring tool recommendations that can help you know exactly which is the right tool for your business demands.
Use Automation
By digging into the data at a more accurate and human-readable level, it allows you to use the data that is being presented in more substantial ways. More often than not, this data is going to be used in other responsive systems, and this is where automation comes into play. By understanding the trends in play within your systems, you can schedule automated responses to spikes and dips in the data.
This is typically done by feeding the data into other systems through integrations, but several APM or ASM tools come with inbuilt automation options available. Automated alerting is probably the most common form of automation you’ll rely upon, but we discuss that in more detail later. Another typical setup is automated load balancing, which can drastically improve application performance by responding to load demands on your infrastructure faster than a human notification.
Automated ASM (Application Security Monitoring) can also be used to increase security. By setting up automated detection systems that flag anomalous usage data, you can script responses like blocking IP or account access. While it typically falls under network monitoring instead of application monitoring, you can also set thresholds to counteract DDoS attacks, just to add an extra layer of prevention to your network infrastructure.
Ultimately, it’s the job of automation to perform actions that are either too immediate or too bothersome for your colleagues to have to perform. It’s up to you and your team to determine exactly what that might mean for your business.
Maintain your Monitor
Whatever tool you choose to employ, ensure that it is rigorously tested within your environment—which is where demos and free trial periods can shine as opportunities to test the features that are available within the available various tools. This helps prevent faults further down the line.
Because you’re using this tool to monitor the performance and security of your applications, it is wise not to try to build your application monitor, and instead rely on market-tested products. Otherwise, you’re simply creating more avenues for errors as the tool you create may even be less stable than the applications it is designed to monitor—the only way you’d know for sure is to monitor the monitoring software—which is ridiculous. Instead, go with products that are on the market and designed with APM first and foremost.
Depending on the automation processes you have in place, you will also undoubtedly have to maintain and adjust them as circumstances shift. Elements of your application may stop responding to the monitor as either it or the monitor is updated or changed; it is a good idea to keep testing your automation systems to ensure they’re still producing accurate responses.
Monitor the Right Metrics
Because applications are frequently monitored as a portion of the wider network infrastructure rather than separately, poor application performance frequently goes unnoticed. This indicates that the data being tracked doesn't always provide a complete picture—so it’s important to track the correct metrics using a properly outfitted application monitoring tool.
The most important data to pay attention to when monitoring your application are:
- Average Response Time
- Error Rates
- Request Rate
- Application and Server CPU
- Application and Server Memory
You might also want to prioritize monitoring Garbage Collection as part of your APM because some app languages, like Java, employ it as well—Garbage Collection is the process of clearing up memory use in your applications. Another crucial performance indicator that is specific to application performance monitoring is Apdex. It is a score in decimal form between 0 and 1, and it represents an overall representation of how well your services are accessed by your end users as a whole.
Alerting & Reporting
Setting up an elaborate system to monitor your numerous applications is pointless if the data that you are keeping track of goes unnoticed. Once you have set up all of the necessary automation and are tracking the correct metrics, you should also set up proper alerting. Almost all professional application monitoring tools come with highly customizable altering options that can detect anomalous or unhealthy spikes in your data—use these liberally.
It’s also vital to make sure these alerts are going somewhere that they’re going to be seen and acted upon quickly. Don’t be afraid to set the alerting for multiple destinations, like your Slack, email, and texts all in one alert. Making sure that the alerts are caught and handled will be the difference between outages and performance degradation that will cost your business substantial amounts of money and productivity.
On the other side of this methodology is reporting; namely scheduled reporting that you can use to consistently keep track of your performance and security data over longer periods. Reporting data can be plugged into any number of forecasting solutions to track trends in your application usage data, which can be especially useful when considering an upgrade.
Reporting is also useful because it can be used to present otherwise tech-heavy data in a more readable and non-technical way, which is useful when showing the data to your colleagues in other departments. Reporting data might also be necessary for certain compliance requirements, especially regarding user data security.
Communicate with your Vendor
A simple but crucial tip that goes for basically any big product that you’re adding to your network infrastructure: establish a line of communication with your vendor. This is useful across the board, but particularly for application monitors because of the sheer number of integrations and unique data sets, you’ll need to track.
This is the kind of thing that the vendor will be able to support you with, especially if you’re using their API to integrate your bespoke product requirements into their monitoring tool. They’ll be able to provide the right documentation, and even help out with some of the code required to get you properly set up and integrated—remember, they want you on their platform, so they’re going to be more than willing to help you stay.
Pick the Right Tool
In the same way network monitoring tools give correct data on your hardware, application monitoring solutions fulfill the requirements for accurate APM and ASM. There is a lot of overlap between these kinds of tools, and some of the top network monitors available today also deal with application monitoring, either as a part of their main offering or as a supplementary service that can be added to your network.
There are a few important factors to consider if you're unsure what to look for in an application monitoring tool. The ability of the solution to manage your applications is one of the most crucial alternatives; if it can't, it's probably not the right one for you. These software-level integration tools work with your apps to analyze the infrastructure at the code level while utilizing plugins and logging metrics. Since you need to make sure that all of your applications are compatible with the tool you're using, the availability of integrations is frequently the deciding factor when selecting an application monitoring solution.
