APM Defined

“In the fields of information technology and systems management, application performance management (APM), is the monitoring and managing of performance and availability of software applications. APM strives to detect and diagnose application performance problems to maintain an expected level of service. APM is the translation of IT metrics into business meaning (i.e. value).”http://en.wikipedia.org/wiki/Application_Performance_Management

“5 Dimensions of APM*”

1. End user experience monitoring - (Active and passive)

2. Application runtime architecture discovery and modeling

3. User-defined transaction profiling (also called business transaction management)

4. Application component monitoring5. Reporting & Application data analytics

#1See the Big Picture

(aka Systems Thinking)

DevOpsGuys

@DevOpsGuys www.devopsguys.com 14

Systems Thinking 101

“Systems thinking is a framework for seeing interrelationships rather than things, for seeing patterns rather than static snapshots. It is a set of general principles spanning fields as diverse as physical and social sciences, engineering and management.” - Peter Senge
