Today, digital experience means everything. Businesses must deliver uninterrupted services to their end users. But since?modern applications are complex, and complex applications tend to fail in complex ways, it's essential to identify and resolve issues as soon as possible.??
This is where an APM tool?is handy. With an application monitoring tool in place, you can drill down to the exact line of code or?the?component that’s causing problems and?identify the root cause of issues in?minimal time. ??
Measuring?application performance goes beyond application availability and responsiveness.?It’s crucial to?establish a?baseline?for key parameters,?as this helps you?detect application degradation or anomalies.?To begin, measure your application performance with these KPIs:?
An?APM tool can alert?DevOps teams?immediately when?an application behaves erratically.?These continuous monitoring solutions provide key insights on?errors,?including stacktraces, and enable?DevOps to take further actions during an emergency, like applying a quick patch, running an automation script, or reporting?details?to the concerned teams.
APM?tools?provide a bird's-eye view of?application topology, making it easier to identify unresponsive nodes instantly.?Alerting systems and anomaly detection provide the edge?IT?admins need to respond to critical events faster.
APM?tools aggregate performance metrics over a long period of time, and provide a quick snapshot of?performance-intensive operations. This enables?operations teams to identify areas of improvement based on historic trends in application behavior.
Ensuring that a new update enhances response time, or deciding to revert to?an?earlier build, requires a comparison of key metrics before and after?deployment. APM?tools with options to mark significant infrastructure updates as milestones?and?compare?reports?make this a breeze.
APM eliminates the need for developers to manually gather key environmental details required to simulate and fix an issue.?These tools capture the entire application context in depth, including stacktraces, session details, calls to databases, and other dependent components. APM tools even provide APIs for developers to define their own application-specific metrics.
According to Gartner, "APM is a suite of monitoring software comprising digital experience monitoring, application discovery, tracing, and diagnostics and purpose built AI for IT operations."
Originally used to merely monitor performance metrics, APM tools have come a long way?in accordance with the trends?in application development. In?a?nutshell, present-day APM tools should be able to integrate well with other aspects of?monitoring,?have robust?tracing mechanisms, and?aid?in proactive monitoring with the help of anomaly detection and forecasting.?
An APM tool should?be able to?map the various aspects of your application's complexities to give you a better understanding of how the application works.? When?selecting an APM tool for your monitoring purposes, look for these basic features:
Applications?generally?communicate with one or more external resources to complete various actions, be it caching, updating?the database,?or?waiting for an external provider like?a?payment gateway. Visualizing these dependencies helps DevOps and IT?admins?quickly identify bottlenecks and remediate issues.
Monitor the performance of business-critical transactions at a glance by labeling them?as key transactions. Doing so?enables you to save?time?searching for?transactions?and helps you debug and analyze them with ease.
With?distributed?tracing, you can track transaction traces made from one application to another. This enables you to monitor calls made between applications and?isolate?problems.?
Knowing when and how frequently errors happen in?an application enables organizations?to?develop crucial strategies to build?more?robust products and?make the user experience more seamless.
Enabling?developers to customize application-specific metrics?ensures they can?evaluate?performance bottlenecks and tweak?the existing codebase.?
Milestone markers?help you?record?significant events in your application’s life cycle,?like build deployments, product updates, feature enhancements, and infrastructure upgrades.
With a continuous monitoring solution offloading most of the operations-related worries, alerting is just the icing on the cake.?DevOps teams can set up rules to?receive alerts during an irregularity, freeing up?their?time?to manage other day-to-day operations since they won’t have to constantly check?on the metrics.
The idea behind?anomaly detection is to?uncover any?abnormal spikes in?an?application's critical performance attributes.?An anomaly is triggered when a KPI?falls below or exceeds the previously benchmarked values. This?helps you handle?unforeseen issues that?could have a big impact?later.
Reduction in response time.
Reduced DB calls.
Reduced calls to external components.
Optimization in SQL queries.
The following are a few pointers that needs to be considered before buying an APM tool:
