Why is application performance management important?
Application environments can be complex, but users will always expect apps to work regardless of time, which device they are using, or where they are located. Thus, monitoring the performance of business-critical apps is crucial to helping your business thrive and remain competitive. APM is an important solution used to ensure your applications can continue to meet your end-users expectations.
How does application performance monitoring work?
Application performance monitoring tools analyze how applications perform in order to determine if they are behaving correctly. If an app is not working appropriately, data and metadata are collected on the source of the issue. That data is then analyzed to observe its impact on the business and the information is then used for troubleshooting issues and optimizing performance levels. To do this, various types of instrumentation are used (such as distributed tracing of end-to-end transactions, agents for tracing Java or .NET code, APIs for observability, cloud or other platforms, etc.). The conclusive data and application performance metrics are usually visualized via intuitive dashboards. If and when performance levels exceed automatically-defined baselines, organizations can resolve issues by tracing transaction performance across their distributed infrastructure and can also utilize application mapping visualizations to clearly understand the dynamic and complex relationships between relevant components.
What are application performance metrics?
Measuring the performance of your applications involves the following metrics:
- User satisfaction/Apdex Scores: Apdex (application performance index) score helps specify goals for how long a specific transaction of web request should take. The transactions are then categorized into fast, sluggish, slow, or failed requests and scored from 0 to 1.
- Response time: Average response times are useful to track application performance.
- Error rates: This is a critical app performance metric that helps you monitor errors before they affect your end-users. Error rates can be tracked via HTTP error %, logged exceptions, and thrown exceptions.
- Application instances: Having a count of how many application instances are running is important if your application scales up or down in the cloud. This can save money for your organization during off-peak times, and can also ensure your application scales appropriately to meet demand.
- Request rates: Knowing how much traffic your application receives can impact the success of your application. Request rates can help you understand the dynamics of your application’s scalability. By monitoring the request rate, you can also detect spikes or inactivity.
- CPU usage: Application and server CPU usage is a critical performance metric. Observing CPU usage will alert your teams of performance monitoring issues. It is especially important to them per server, but also to track them as an aggregate across individually deployed instances of your application.
- Application availability: This form of monitoring is a useful method to measure uptime for service level agreements (SLA). For web applications, this can be done via a scheduled HTTP check, which can monitor status codes and response times, and can search for specific content on web pages.
- Garbage collection: For applications written in C#, .NET, or other programming languages that utilize garbage collection, it can create performance problems such as causing your process to suspend or using a lot of CPU.
How do you test application performance?
It is important to test your application performance to prevent bottlenecks and ensure a seamless end-user experience. To test your application performance you need to:
- Identify the testing environment: Identify software, hardware, and network configurations.
- Identify performance metrics: Beyond response time, throughput, and constraint metrics, determine the other success criteria for your performance testing.
- Design your performance tests: Plan different performance test scenarios while keeping in mind account user variabilities, testing data, and target metrics.
- Configuration: Configure the test environment and the instruments necessary to monitor your resources.
- Implement your test design: After you have created your test model, implement your test design and develop the tests.
- Execute: When you run the performance tests, make sure to monitor and capture the data generated.
- Retest: Analyze, report, and then retest the data. Run performance tests again using the original defined parameters as well as different parameters. Then, share the results.
Application Performance Monitoring Solutions
The best application performance monitoring solutions (APM) are important for proactively monitoring and managing a software application’s performance and availability. APM’s scope further includes performance measurement for virtually any IT asset that affects end user experience. The sign of the best APM tools are that they detect application performance issues in order to adhere to an agreed-upon service level. In particular, APM is focused on app response times under various load conditions. As part of this, APM also measures the compute resources required to support a given level of load.
According to members of the IT Central Station (soon to be Peerspot) community, the best APM vendors serve multiple masters. Developers need to understand app performance characteristics in order to ensure an optimal software experience for end users. Business managers and IT department leaders use APM data to help make decisions about infrastructure and architecture.
As applications grow more complex and interdependent, application performance monitoring users express high expectations for potential APM toolsets. Accessibility, manageability and scalability are essential. Users argue that an effective APM tool must give business stakeholders accurate, understandable data while allowing developers to dive deeply into stored data over the long term.
DevOps users want app performance management tools to measure the deep internal transactions that take place inside an application or between integrated system elements. They want APM data in real time, across multiple application tiers, with transparency along the entire application process chain. Some refer to this as “full stack tracing.”
Ideally, APM data should be measured against user experience as a key performance indicator. For example, if a bottleneck is being caused by database latency, users want to understand the root cause so they can fix it immediately. This might require an alerting based on patterns and “baselining.”
Some expect APM tools to enable the discovery of complex distributed application architecture or even microservices and containers. After all, not all application architecture is known at the outset, and it certainly changes over time. Users need APM tools to be proactive whether they are used in dev, test, QA or production environments.
The APM toolset itself should have low impact on application performance. The measurements it takes have to be easy to interpret and place into a business-friendly reporting output. For instance, IT Central Station members suggest that APM tools should offer a predefined customizable reporting capability, with high visibility and a capacity to export and report on large quantities of raw data.
Benefits of Application Performance Management Tools
Application performance management tools include a long list of benefits. Below are some of the most reputable ones:
- Visibility: With APM tools, you gain visibility across your entire application stack. You have access to the complete infrastructure, front-end, and back-end, and cloud components to ensure your application can perform at its best.
- Performance insights: When you implement an APM solution, you are alerted when performance deviates from its typical normal behavior, or when anomalies are detected so you can quickly remediate any issues.
- Root-cause analysis: A good APM tool will allow you to identify what caused an issue and where it is coming from.
- Early prediction: Application performance management tools will equip your IT teams with the information they need to tackle potential performance issues ahead of time so that they can be proactively prevented. An APM tool will use a combination of historical data and advanced metrics to highlight vulnerabilities, root causes, and trouble areas before they evolve into bigger, more significant problems.
- Monitor third-party applications: Ensure that service level agreements (SLAs) are being met. Through the use of advanced analytics, APM can alert you when a third-party service is identified as the root cause of a performance issue. With this information at hand, you can react with a faster response time and modify or remove any problematic assets.
- Deeper understanding of user experiences: Synthetic and real-user monitoring help predict user behavior paths so you can identify areas in need of optimization to improve a user’s experience.
Features of Application Performance Management Tools
A great application performance management tool will include features that will help you optimize the success of your organization.
- Artificial intelligence (AI) and machine learning (ML): When an APM tool uses AI and ML to monitor your application’s performance, it allows you to be proactive in resolving issues before they emerge into major problems.
- Automatic business transaction identification: This feature should not be overlooked. Without being able to identify and display application transactions, you lack the ability to prioritize problems and risk flying blind in alert storms.
- Customer interaction information: For customer-facing applications, this feature will provide access to the customer numbers or locations via easy data queries, customized dashboards, or report creation capabilities.
- Automated issue remediation: A good APM feature to have is the facilitation of automated issue remediations which can help your organization automatically run defined actions to help resolve issues before they negatively impact your business. An APM tool can mitigate the impact of a problem using features that facilitate extra capacity where needed when auto-scaling in the cloud.
Other critical features to consider are easy deployment, a user-friendly interface, privacy regulations support, and real-time analysis.
