Application Performance Management APM: An Introduction

Now that you know what is APM and how it works, it is recommended that you implement it in your company to gain all the benefits of it. Proper usage of the data retrieved from the analysis can tell you quite a lot about the issues the application is experiencing. The picture below indicates all the processes that must be available in the APM’s workflow. Imagine a situation where your application suffers from a slow system response. This will mean that your customers will have to wait for a very long time before any operation is processed. Modern people are always in a hurry, so it is unlikely that anyone will wait until the system “thinks”.

How does APM discover performance issues

IT automation, powered by AI Achieve new levels of efficiency and resiliency in your IT operations. Application and server, virtual machine, or container CPU usage – the CPU usage of the underlying infrastructure. Number of application instances – the number of instances of some application. In today’s dynamic deployments this number typically varies with traffic, application usage, etc.

APM workflow organization

For instance, an APM platform must monitor network communications to see if there is a communication problem between the application and any cloud services it requires to run, or between the application and the users themselves. To do so, many tools monitor both latency and the number of incoming and outgoing requests an application makes. If memory usage is high, application performance issues will arise. Trying to manually maintain, configure, script, and source data in a cloud-native environment is beyond human capabilities, which means organizations must continuously automate these tasks to ensure proper application performance. Dynatrace enables automation through automatic deployment, configuration, discovery, topology, performance, and updates. Davis® doesn’t need to learn because it already knows, and is continuously and automatically observing, analyzing, providing answers, and prioritizing what matters.

That samples factors such as CPU utilization, disk space, and network performance. Stack monitoring typically includes code-level tracing, which can help spot portions of code that might be causing a performance bottleneck. This is a map of how all the components of your application communicate with each other. APM tools automatically discover these dependencies and interactions and update them in real-time.

How does APM discover performance issues

Pull metrics from any component and collect cloud native metrics at scale. Take advantage of existing Prometheus exporters or write custom metrics source to have the exact metrics needed for optimal monitoring. Enables the collection of data from browser to app and measure true end-to-end user experience. Get insights into application behavior using a flexible query language. Filter and cluster trace data using out of the box or custom dimensions for comprehensive analysis. Such tools are easier to use, but they provide limited information.

Transaction Tracing

In a highly distributed environment, network monitoring becomes a key piece of the puzzle in understanding the behavior of your networked services. 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 application performance management (APM) resources and experienced events within the app performance infrastructure. This includes an analysis of all servers, operating systems, middleware, application components and network components. Component monitoring provides a deeper understanding of the various elements and pathways identified in the previous processes.

Select APM tools based on the monitoring needs for the application and its operational environment. Simple APM tools might be inflexible or inadequate, while complex tools might be too difficult to manage or be underutilized. Shop around, use proof-of-principle testing and choose an APM tool that is most appropriate. In virtualized deployments, APM tools can help IT professionals monitor application servers to ensure that they comply with an SLA. Automatically created by an application or OS, they hold information about user behavior and events that took place on the app.

How do I benefit from APM?

Modern software systems can be broken down into a few high-level components, typically designed and developed by different organizations and run in different runtime environments. An application or operating system creates log files that include information about user activity and events that occurred on the application. Root cause analysis, understanding why a measure changed and determining where an event started are all done via log files.

The Network Map visualizes network traffic between any tagged object in our environment, from services to pods to cloud regions. Now that we’ve determined the root cause, we can begin to focus our remediation efforts. By digging into our code’s deployment history, we can surface any recent deployments that may line up with the spike in cross-AZ traffic volume, and then audit the changes. Issuing a timely rollback, we’ll relieve our web-store service of the undue overhead and mitigate what could have been a significant increase in our cloud provider bill.

Localization, multilingual content, and a network of smaller microsites are popular characteristics of company websites. They frequently demand elaborate role-based access requirements as well, all of which can make the website’s technological architecture more complicated. It indicates how clients feel about the application in comparison to a pre-determined benchmark.

An ideal APM tool should be flexible and support all the necessary monitorable touch points in an IT setup. However, one must realize that digital application monitoring needs vary hugely between organizations and thus APM requirements are defined differently in different contexts. While some organizations make do with a combination of multiple tools for monitoring, alerting and reporting, an ideal APM software presents a unified console for all monitoring requirements. Before making a choice of APM solutions, IT and DevOps professionals in the APM sphere should thoroughly analyse the specific capabilities given below for the right application performance results.

Application Performance Monitoring Strategy Requirements:

Content distribution networks, APIs, caches and databases are just some things that a successful application requires to thrive. Manually monitoring each service is simply impractical without the use of an APM platform. APM solutions provide alerting systems to Devops, IT Operations, Site Reliability Engineers, and more to quickly troubleshoot performance issues and slowdowns. These techniques can’t help you analyze the interdependencies between components when you work with a distributed application. Logs, metrics, events are everywhere – in the cloud, across clouds, in hybrid clouds – sometimes hard to locate and manage, thus hard to find out why your app is running slow. As mentioned earlier, ideal APM tools should pack the essentials i.e. all round monitoring, alerting and comprehensive reporting, eliminating the hassle of having to deal with multiple tools to measure and optimize application performance.

  • Having logs, metrics, and APM traces all stored and indexed in Elasticsearch is super powerful.
  • It is an excellent approach to get a broad picture of all applications traversing the network while integrating easily and passively into the IT infrastructure.
  • You must dig right down to the code level if you want to figure out why your application is slow, generating errors, or has issues.
  • Both types of work should be used together because they are crucial in the detection and solution of any issues regarding the performance of the software.

Modern applications must deliver not only value but also round-the-clock availability, quick replies, and real-time problem-solving in today’s digital economy. Since all businesses rely on software applications, their performance is one of their primary worries and frustrations, especially if their applications are the business itself. This is where Application Performance Monitoring Tool enters the scene. By correlating logs with this trace, we observe a series of timeout errors being thrown by requests to the ShoppingCartController#checkout endpoint. Our trace surfaces spans for the function recommendationController.addPurchases that are attempting to run for over fifteen seconds before timing out.

Among other things, logs can be used to create a high-fidelity, millisecond-by-millisecond record of every event, complete with surrounding context, that developers can ‘play back’ for troubleshooting and debugging purposes. Consider the ease of use in terms of changing metrics, creating custom metrics and accommodating new use cases. Understand how prospective tools and processes can adapt to changing business needs into the future.

How does application performance monitoring compare to container monitoring?

It captures user-based performance data to assess how well the application is running for users and to gauge potential performance concerns, also known as end-user experience monitoring. Real-time user monitoring allows a company to quickly respond to issues and understand their consequences. It entails tracking all IT infrastructure components and is also known as an application component deep dive. Component monitoring provides a deeper understanding of the many elements and pathways uncovered during the preceding methods.

Why is application monitoring important?

Today APM tools are leveraging observability and AI in varying degrees. Some are combining traditional application performance monitoring with AI to automate discovery of changing transaction paths and application dependencies. Others are combining observability with AI to automatically determine performance baselines, and to sift signals, or actionable insights, from the ‘noise’ of IT operations management data. Industry analyst Gartner finds that organizations can realize a “60% noise reduction in ITOM through use of AI-augmented tools.” Most APM solutions provide visibility all the way till the level of code to help discover problems that might otherwise go unnoticed until an end user reports it. Your APM solution should be able to take snapshots of individual transaction traces and allow you to drill down to the SQL queries to detect slow running queries.

However, while these do have their own – important – role in a monitoring strategy, they need additional configuration until they can offer the same perks as an APM tool. Application Performance Management is the broader strategy of managing the overall performance, starting with code, application dependencies, transaction times, and user experience. It points out, typically via alert notifications, that there is a problem. Root cause analysis is even more challenging for applications that build on top of large ecosystems of microservices. Distributed tracing is of crucial importance when debugging issues in such a system. One user request or transaction can travel through many different services in different runtime environments.

Infrastructure monitoring

It can help teams understand the context and root cause behind a performance issue by correlating across logs, metrics, and traces. Identify database-related issues and visualize end-to-end application performance with database monitoring tools and alerts. Tracking performance metrics including top users, objects, and programs, along with the ability to review execution plans for slow SQL, provides valuable insights that allow teams to isolate bottlenecks. In a nutshell, APM software provides the tools necessary to quickly discover, isolate and solve performance issues that would otherwise hurt the end-user experience. While every tool works a little bit differently, the general aim behind most APM platforms is that they aggregate application performance metrics using everything from log files to hardware component statistics to network throughput reports. In other words, if the tools generate information, they then quantify that information.
