What is APM? Application Performance Monitoring Guide

In an effort to create a standard definition for grouping software products, Gartner introduced a definition that we will review here. In doing so, it’s easier to drill down root causes and automatically addressing key issues before they effect end-user experience. Innovate faster, reduce operational cost and transform IT operations (ITOps) with an AIOps platform that delivers visibility into performance data and dependencies across environments. With these questions answered, a business can make decisions to move forward with an APM deployment. It’s often best to start small — with a single application or service — develop expertise with the APM tool and practice, and then systematically expand APM use as required.

In addition, the teams will integrate new features and functionalities to improve the end-user experience, as well as ensure that the applications adhere to industry standards and compliance regulations. Application performance management (APM) software helps an organization ensure that its critical applications meet established expectations for performance, availability and customer or end-user experience. Also known as application component deep dive, this aspect involves tracking all components of the IT infrastructure. Extensive, in-depth monitoring is performed on all the used resources and experienced events within the app performance infrastructure.

They were throttling us and the only way we would have ever known is because track all of the exceptions and can see in our APM that those affected transactions were also failing. APMs help you identify what’s working just as much as what isn’t working–that way, you can replicate your successes elsewhere. See why developers love using Retrace to proactively find and fix APM issues.

Given the large number of potential tools, organizations should be sure to invest time and effort in feature evaluation and product selection. The analytics and reporting components are essential to ensuring the organization receives a good return on investment (ROI) from both the application and APM. Some vendors have put a huge focus on making their products affordable and very easy to use so they can be available to the development and operations teams of all sizes. For example, a development or operations team can instantly tell from this visual that their database is causing some performance spikes. They can also leverage their APM to identify exactly which database query and web requests were affected.

Passive monitoring is usually an agentless appliance implemented using network port mirroring. A key feature to consider is the ability to support multi-component analytics (e.g., database, client/browser). Active monitoring, on the other hand, consists of synthetic probes and web robots predefined to report system availability and business transactions. Active monitoring is a good complement to passive monitoring; together, these two components help provide visibility into application health during off-peak hours when transaction volume is low.

Now, on one level, delivering the technical functionality of Gartner’s five dimensions is relatively straightforward. Most performance monitoring tools rely on automated methods of packet capture, endpoint instrumentation, and JavaScript page-tagging or code injections into a browser or application in order to collect data. Plus, the proliferation of SaaS solutions for APM, which take only minutes to set up, means that users are always running the latest version of the software and should never have to update tagging scripts or other components themselves. We all know from firsthand experience that nothing irks end users more than unexpectedly slow response times. In fact, slowness is arguably a bigger problem than application downtime and unavailability. Research on ecommerce websites shows that slowdowns occur ten times more often than outages, and those cumulative slowdowns add up to twice the impact to an online store’s bottom line.

Teams can use synthetic testing to proactively detect user-facing issues and prevent breaking changes from reaching production. They can also leverage deployment tracking tools to ensure code changes have not introduced performance regressions. This enables them to sustain a rapid development pace and bring more features to market. IT professionals can create rules and select monitoring parameters so the APM tool alerts them when a problem arises or when an application’s performance dips in a specific area — or deviates from an established baseline. They can also prioritize applications based on how business-critical they are.

So, What Exactly Is APM

Simply put, application performance management is the art of managing the performance, availability, and user experience of software applications. APM monitors the speed at which transactions are performed both by end-users and by the systems and network infrastructure that support a software application, providing an end-to-end overview of potential bottlenecks and service interruptions. Load testing, synthetic monitoring and real-user monitoring, and root-cause analysis are a few of the primary tools to be found in a well-rounded approach to APM. Another significant component of APM is web performance monitoring (WPM), or the use of web-monitoring tools to gauge app speed and uptime. In less pragmatic terms, however, APM is ultimately a perspective—an analytical view brought to bear on every aspect of software performance in order to clearly understand, and continuously improve, the end-user experience. Developers, for instance, can use popular APM software suites to collaborate more effectively with operations teams, manage the quality of their work through code-level troubleshooting, and monitor project progress with easily generated reports.

In doing so, your APM greatly reduces your mean time to resolution (MTTR). This is due to root cause analysis, which allows you to winnow down to the heart of the issue. That way, you don’t have to fight your way through manual troubleshooting–you just get it right the first time. APM systems monitor almost any form of information that plays a role in application availability, all with the goal of improving the application for the business using it. Think of it as a smarter way to see the big picture–and correct the big picture before your customers notice any flaws. Teams can leverage a service inventory and distributed tracing to ensure that crucial transitions, such as cloud migrations or modernizations, do not introduce regressions.

The terms application performance monitoring and observability are often used interchangeably, but they can diverge in scope. Automated load balancing has the potential to trick IT professionals into thinking everything is working properly because the combined performance of the servers appears to be fine. In reality, the automation could be masking issues where some servers are carrying more of the load than others.

However, they are not always aware of the resources the software may take up, such as using an excessive amount of memory (RAM). DEM suites typically include Real User Monitoring (RUM) and synthetic testing, which both play an important role in detecting and reducing user-facing issues. RUM not only allows teams to collect and alert on real-time metrics such as load times, error rates, and Core Web Vitals, but also captures video recordings of user sessions to help teams better understand the specific conditions around frontend problems. Synthetic testing, meanwhile, simulates user traffic in order to help teams proactively detect issues with key endpoints and user journeys. A service inventory provides high-level visibility into the health metrics, dependencies, deployments, and monitors of all services in a given application—and allows you to search and filter specific services and their dependencies. It also typically includes service maps, which help developers visualize the topology of applications in order to monitor service health in context.

Knowing your server CPU or average response of your webserver is important and helpful, but APM aims to go way deeper. If you provide support for application components or the infrastructure components that service the applications then APM is an invaluable tool for your job. If you are a developer the absolutely yes, APM fits right in with the entire software development lifecycle. If your company is adopting a DevOps philosophy, APM is a tool that is collaborative at it’s core and enables developers and operations staff to work more effectively. Companies that are using APM tools consider them a competitive advantage because they resolve problems faster, solve more issues over time, and provide meaningful business insight. This helps lay the foundation for event correlation and provides the basis for a general understanding of how network topologies interact with application architectures.

• It also typically includes service maps, which help developers visualize the topology of applications in order to monitor service health in context.
• Continually optimizing the end-users’ actual experience of your application’s performance, reliability, speed, and functionality is not merely a minor footnote in the annals of APM—it’s the moral of the story.
• Their prescriptive/predictive capabilities will often highlight issues before they impact the end user, and although these types of tools can be pricey, the opportunity cost will almost certainly be greater.
• EAM utilizes your existing monitoring stack so there’s no need for any news agents, databases, or infrastructure.

Since DDCM is closely related to the second dimension in the APM model, most products in this field also provide application discovery dependency mapping (ADDM) as part of their offering. No matter whether you’re creating smartphone apps, service-oriented software, or online video games, you’re bound to be bitten by multiple components of your system architecture throughout any application development life cycle. Just a single weak link in the chain can negatively impact your application’s performance, instantly resulting in a slew of unhappy end-users downstream. Again, APM gathers software application performance data, analyzes it to detect potential performance problems, and provides information or takes action to accelerate resolution of those problems. The chief difference in how they gather and analyze the data is the difference between application performance monitoring and observability. An enterprise workload that functions poorly, experiences frequent software or infrastructure issues or poses availability challenges will incur costs to troubleshoot and remediate.

You’ll also hear the term Application Performance Monitoring used interchangeably and that is just fine. Some will debate the details of monitoring versus management and in reality there is an important difference but from a terminology perspective it’s a bit nit-picky. Not a major one, but a small bug that could fester into https://www.globalcloudteam.com/ a much larger problem. Only a few users notice it at first, but it can easily turn into a performance issue if left unchecked. Once it identifies a problem, it alerts administrators so that they can quickly fix the issue before it can spiral. This website is using a security service to protect itself from online attacks.

Analytics – This term leaves a lot to be desired since it can be and often is very liberally interpreted. To me, analytics (in the context of APM) means baselining, and correlating data to provide actionable information. To others analytics can be as basic as providing reporting capabilities that simply format the raw data in a more consumable manner. I think analytics should help identify and solve problems and be more than just reporting but that is my personal opinion.
