What Is APM: Application Performance Monitoring Guide

These platform solutions offer more high-level tracking and end-to-end monitoring capabilities. Server monitoring involves collecting metrics that relate to infrastructure, such as Disk I/O, CPU utilization, memory usage, and throughput, to gain insight on web and application servers. Server monitoring facilitates troubleshooting by providing code level details as well as data that allows IT operations to track server metrics and trends over time. It is rare for applications at scale to not require some sort of network component. Whether it is communicating with dependent services or directly with the end user, reliable network communication is paramount to application performance. Because of this, most APM tools offer mechanisms for monitoring not only network latency, but also the number of requests — both incoming and outgoing — as well as the response status of those requests.

  • Application Performance Monitoring is the strategy and practice of continuously monitoring and tracking application performance and availability, as well as end-user experience.
  • As mentioned, application performance monitoring observes how applications are performing and if they’re functioning appropriately.
  • Modern applications such as mobile apps, websites, and business apps may seem simple on the surface, but they are actually highly complex.
  • Causes can run the gamut — from coding errors to database slowdowns to hosting or network performance issues.
  • These are typically mission-critical workloads that the business depends upon, and where disruption would affect the business.

APM solutions are always developing to keep up with the demands of the fast-changing technologies we use to construct applications. We’re on the verge of a huge shift that will propel APM forward to the next stage of its evolution at the time of writing. Logs are granular, timestamped, complete and immutable records of application events.

How does APM discover performance issues?

Observability focuses on collecting more data across a broader range of environments and then performs sophisticated analytics on data patterns to provide insights on large and complex environments. An enterprise workload that functions poorly, experiences frequent software or infrastructure issues or poses availability challenges will incur costs to troubleshoot and remediate. Application monitoring helps identify problems for rapid correction. In some cases, prompt remediation can take place before users are even aware of an issue. The cost of APM can bring direct cost savings in unneeded application downtime and troubleshooting. IT professionals can use the performance metrics — which an APM tool gathers from a specific application or multiple applications on the same network — to identify the root cause of a problem.

APM tools typically include monitoring of key metrics such as response time, throughput, and error rate to identify and diagnose performance bottlenecks and issues. APM solutions collect, monitor, and analyze telemetry data from websites, software applications, and services. Teams get end-to-end visibility across their applications so they can understand application and service dependencies and address any errors or slowdowns. APM solutions also store and utilize historical data to surface trends and detect outliers for key performance indicators, such as latency and throughput, as well as business KPIs. You’re able to answer questions about specific page load times and database queries in a way that you simply can’t with traditional host-based monitoring.

Monitoring users

However, it will still happen, and it is something you should monitor. It’s also critical to monitor things like the server’s CPU and memory. Although many recent web applications are not CPU-bound, they will still consume a significant amount of CPU, which is a useful indicator for auto-scaling your application in the cloud.

Application performance monitoring helps businesses track the performance of software applications to identify and drill down into issues that occur during development and runtime. As mentioned, application performance monitoring observes how applications are performing and if they’re functioning appropriately. If they’re not, then the monitoring tool collects data on the source of the issue, alerting IT teams so they can correlate the performance of a specific application or set of applications to business or outcomes. It also allows them to identify and address performance issues on the backend before they affect end-user experience or negatively impact the bottom line. In today’s digital world, applications are no longer an add-on — they’re often the lifeblood of the business itself. That’s why when business transactions are interrupted by outages, slowdowns, or hiccups in the digital experience, it can result in the loss of not only a sale, but also brand reputation and trust.

Many application and server-related metrics are collected by these APM solutions. The APM tool then uses this information to figure out which of your application’s URL requests are taking too long. Since they don’t profile the application’s code, they can’t tell you what’s causing the slowdown.

Teams are dealing with massive amounts of data streaming in real time. Complex, distributed applications — especially those using cloud-native technologies — can make APM instrumentation a challenge. If there are issues across an environment or complex root cause analysis cases, many tools can struggle. It is important when selecting a tool that it includes dashboards and views that make it easy to track a user’s experience and identify errors and issues at-a-glance. Most teams start investigations around reported issues, and then work to identify the root cause. Having a platform approach to APM avoids tool switching at this stage.

Using historical and baseline data, can also quickly identify, locate, and rectify performance issues. The analytics and reporting components are critical to achieving a positive return on investment for the organization. While application performance monitoring is limited to measuring an application’s performance, application performance management includes the broader idea of controlling an application’s performance levels, which includes monitoring. Discover and address ‘unknown unknowns’ – issues you don’t know exist.A chief limitation of monitoring tools is that they only watch for ‘known unknowns’ – exceptional conditions you already know to watch for.

Video Intelligent app resource management with AI-powered automation Gain full visibility into your application and infrastructure resource allocation which contribute to user response time and any resource congestion. Availability monitoringmonitors the actual availability of application and hardware components(because applications can generate performance data even when they aren’t accessible to the end user). Sematext uses this data along with error rates and failed transactions to build a dynamic map of your complete app architecture – including connections to external services and databases – that shows how all components interact with each other. The AppMap makes it easier for you to track application health and performance. IT operations analytics refers to analyzing data to identify usage patterns, trends, and performance issues that you can leverage to build a better plan on how to deal with similar situations before they occur and affect end-users.

The reality is that the new competitive battlefield is digital, and the winners and losers are defined by the experience they provide. A trace is a record of how a request was processed from beginning to end. A trace is a tool for visualizing and comprehending a request’s entire path via all of the network’s components and services.

Application Performance Monitoring: A complete overview for 2022

An effective APM platform provides an organization with the ability to connect their app performance to their business outcomes, isolate and fix errors before they affect the end user and reduce the mean repair time. The Dynatrace software intelligence platform provides all-in-one advanced observability for APM use cases that serve business, operations, application performance management (APM) application. AI assistance enables teams to automate operations, release software faster, and deliver better business outcomes. With the Davis® AI engine at its core, Dynatrace provides precise answers to complex questions in real time. However, digital teams often find it difficult to find the root cause of an application performance problem.

This prevents the checkout process from completing, triggering TCP retransmits—thus, we can conclude that this issue may be a significant contributor to web-store’s connectivity issues that we had previously spotted in NPM. We’ve used APM to uproot an issue on a particular endpoint of our service, and we can now work towards releasing a code fix. Thanks to unified tagging, we can use NPM to identify potential application issues to troubleshoot in APM. For example, we can start in the Network page to get a high-level view of pod communication and health across our environment. This could indicate that a misconfiguration or code error on either the source or destination endpoint is causing requests to hang, leading to packet loss. Establishing a process, from generating alerts to crafting automated responses to issues, should be a dynamic effort that is revisited and updated on a regular basis as application and business needs change.

Why should you implement Application Performance Management?

In a time when changing service providers is as easy as opening a new browser window, it’s crucial for organizations to guarantee their applications are at peak performance. The good news is that dedicated container monitoring solutions are now widely available, so managing containerized application performance is just as possible today as managing traditional application performance. Application Availability and Uptime – Determines whether the application is online and available to users; it’s typically used to verify if an organization’s service level agreement is being met. Compiling data across monitoring platforms into a solitary source of information increases the productivity of your IT environment by reducing time spent manually searching through event logs or building synthetic monitors. Measuring average response time or MTTR helps determine whether speed is having an impact on app performance. Synthetic monitoring utilizes behavioral scripts to simulate user behavior, and is helpful for the development and testing process prior to deployment or while making changes to a digital asset.

Having the data available in a visual form makes problem detection easier. Elastic APM Real User Monitoring monitors the real user experience within your client-side application. Trace context is the trace information that accompanies the distributed transaction, including when it passes the service to service over the network or through a message bus. The context contains the trace identifier, span identifier, and any other data that the tracing system needs to propagate to the downstream service.

Why cloud-native applications make APM challenging

Monitoring the uptime of your application is the easiest and most effective method available to check compliance with SLAs. Professional software comes at a price, so you will have to purchase licenses or subscriptions for the tools you want to use. “Alerting” must only inform relevant stakeholders and regard important information to be of any use. “Reporting” must include information about the problems, their influence on the system, and the solution. High-quality reports may also help you to determine the proper route for improvement. Some of the most popular software in this category are Stackify and Dynatrace.

After installing the agents, teams can instrument specific parts of an application or transaction for analysis and then send the data to an endpoint — usually an APM platform. Examples of configurations include environment names, sampling rates, and other metrics. Some APM tools take analysis to the next level by profiling the production code execution. This can come in the form of identifying bottlenecks in the execution of a memory-intensive process, or it can even highlight slow database queries and provide ways to speed them up. This type of analysis is one of the most valuable features an APM platform can provide, as it offers a second set of eyes on everything an application is doing. The CPU is what determines the number of operations per second the server can perform.

For example, not all HTTP headers are automatically forwarded by service infrastructure and routers etc. A trace represents a transaction as it moves through a distributed system. For trace data from one tracer to be understood and consumed by another tracer there has to be a standardized and extensible format for it. To help you choose the right APM solution for your organization, below are a number of key considerations, keeping in mind that budget will be a factor too.
