What is Application Performance Monitoring? 

Application Performance Monitoring or APM is a process or a collection of tools that helps IT teams ensure optimal application performance, reliability, accessibility and user experience (UX). 

APM tools are designed to continuously track a range of metrics and key performance indicators (KPIs) like response time, latency, resource utilization, and error rates in real-time.

Based on this data, it empowers engineers with insights on how applications function, visibility into application components, dependencies, and transactions, and helps identify and diagnose issues. 

Furthermore, APM supports performance optimization by pinpointing bottlenecks, optimizing applications, enhancing scalability, and improving the overall UX.

Why Monitoring Your Application is Important?

Imagine your favorite e-commerce website throwing a major sale, something like a Black Friday, perhaps?

Shoppers flock to the site, adding products to their carts and initiating transactions. The website’s servers are overwhelmed by traffic, causing the database to struggle. Without effective application performance monitoring, your team might remain oblivious to these issues until it’s too late. 

As a result, the website could crash, transactions may fail, and frustrated customers would leave their shopping carts. In this scenario, the absence of proper APM practices can turn any Black Friday blue. 

APM is important as it helps businesses identify and address performance issues, ensuring a good user experience, operational efficiency, and overall business success.
