Often performance management is still confused with performance troubleshooting. Others think that performance management in production is simply about system and JVM level monitoring and that they are already doing APM.
The first perception assumes that APM is about speeding up some arbitrary method performance and the second assumes that performance management is just about discovering that something is slow. Neither of these two is what we at dynaTrace would consider prime drivers for APM in production. So what does it mean to have APM in production and why do you do it?
The reason our customers need APM in their production systems is to understand the impact that end-to-end performance has on their end users and therefore their business. They use this information to optimize and fix their application in a way that has direct and measurable ROI. This might sound easy but in environments that include literally thousands of JVMs and millions of transactions per hour, nothing is easy unless you have the right approach!
