Understanding The Importance of APM’s “What-If”

Recently there has been a lot of talk around the application performance monitoring (APM) world, more specifically revolving around the necessity to aggregate key performance indicators in a non-intrusive environment.

An article recently written on the APMDigest went into detail about the “Butterfly Effect Within IT,” explaining how one change to a line of code at the development stage could have catastrophic effects for the end user who is looking through the graphic interface. The article went on to explain how a dynamic and flexible* APM solution must be configured in order to give up to date statistics around each process that goes into developing and using an application. Certain statistics will be more relevant at different stages of the application however, transaction volume and performance characteristics* will always need to be looked at. This is where the “what-if” ability comes into play.

A “what-if” scenario will allow those involved with the application’s lifecycle development to ensure that their product will continue high levels of service, from start to finish. This is the precipice where APM intersects Capacity Management and advanced analytics opens the door to predictive modeling. The ability to ascertain how the physical and virtual environments will react to a “what if” scenario is why optimizing the application life cycle is so important. Users need to be able to complete “What if” analyses to determine where and how potential changes would affect operations. Through this analysis, users can change any number of factors – CPU capacity, memory, disk, hosts, workloads moving to different hosts, and more – and see the results in easy-to-read graphs well before any changes occur. Therefore, those involved can dynamically understand the effects of change and make decisions to continue high levels of service.

These scenarios are an incredibly powerful feature for all of those inside information technology (IT) departments. Being able to see what will happen, before it actually happens, can mean the difference of a successfully implemented solution or another head-ache for the professionals involved.
