1 Introduction to Measure
The Measure performance monitor is a data collection and measurement tool that
provides a wide range of performance statistics on system resources. You can use the
Measure performance monitor to gather information from systems, network
components, and your own business applications.
You then use the Measure data to balance and tune your system, detect problem
areas or inefficiencies, balance workloads, evaluate sizing for new applications, or for
capacity planning. You can also use the Measure programmatic interface to access a
collection of services and build your own high-level performance tools for capacity
planning, resource accounting, and load balancing.
