Modern enterprises are critically dependent on software applications for driving their digital businesses and delivering software-as-a-service (SaaS) or application-as-a-service. In today’s digital era, accelerated service and application delivery without compromising on the quality is what matters to your customers. But, have you ever thought what impact it would have on the business if your live applications running at the clients’ systems go down or don’t perform as expected?
To improve the overall health of your running applications, you need to have monitoring capabilities and real-time root cause analytics in place. There are various application performance monitoring (APM) suite vendors in the market extending their scope of offerings by integrating functionalities such as cloud-native monitoring with data-derived metrics from activity logs, servers, networks, and application databases.
The following are critical aspects of application performance monitoring:
- End-user experience monitoring, both active and passive
- Discovery of the application runtime architecture
- User-defined or business transaction profiling
- Application component monitoring
- Application data analytics and reporting
What Is Application Monitoring or Application Performance Monitoring (APM)?
Application monitoring is the process of measuring and analyzing the performance of your software applications to ensure their high availability and satisfactory end-user experience. Application performance monitoring helps to ensure your mission-critical applications are performing smoothly and running at an optimum level. For achieving and maintaining certain levels of service, your applications need to be monitored continuously using advanced application monitoring tools. The tools analyze, detect, and diagnose the complex problems degrading or interrupting your app’s performance and uptime.
In the past few years, APM has become increasingly essential for IT professionals, including IT admins, IT operators, developers, and DevOps teams. Integrating application monitoring capabilities into your existing infrastructure should be an integral part of your IT strategy. APM technology is used to gain actionable insights into application performance metrics and business processes with extending capabilities of IT operations management.
A few examples of application performance monitoring are:
- CPU utilization and server monitoring where your applications are hosted and running
- Analyzing access logs of your webserver to compare the number of user requests received versus the amount of time taken to respond to those requests
- Tracking error rates of your every app
- Network traffic monitoring to detect application downtimes
- Measuring and analyzing key performance metrics against app dependencies on programming languages and services like Redis, Elasticsearch, SQL, etc.
- Web application or website monitoring using an analytics platform (e.g., Google Analytics) to check and identify pages with slow speeds also falls under application monitoring.
An application’s performance is usually monitored and measured with two sets of metrics where the first set measures the performance and experience your app is delivering to end users while the second set of parameters analyzes the resources used by your application for computing purposes.
The first set of metrics include:
Application load time, which is the time an app takes to process the volume of transactions, such as requests per second, transactions per second (TPS), or pages per second. It’s an important performance metric to measure your end-user experience—the less time it takes an app to start up, the more satisfactory the experience. It’s essential to monitor all your applications once they’re running live at the client’s server. Developers usually don’t face performance issues during the development phase as the app doesn’t need to be loaded for processing computer-based demands in systems where it’s being built like calculations, searches, and other transactions. Application monitoring tools allow you to check applications slow to load, indicating system issues, coding errors, resource bottlenecks, etc.
Another critical metric is the response times of your applications, defined by the time each app requires to respond to an end user’s request or action even during overloaded situations.
The second set of performance indicators measure:
Cloud or on-premises resources used by your applications for computation. APM tools monitor apps for load efficiency. They check if an app has sufficient capacity to support loads during different scenarios. These tools also look for potential hotspots or locations where performance bottlenecks are likely to arise.
These metrics are defined to achieve a standard baseline for the application performance and help identify any changes or loopholes in case the app behavior deviates from the baseline. This performance baseline is useful for external event correlation and predictive analysis of your app’s future performance.
Applications failing to comply with the metrics and parameters lose their reliability factor, leading to frustrated users who’ll no longer use your software applications.
