Issue/Introduction

Introduction: 

Counter and Interval Counter are standard Introscope metrics for calculators.  This article will describe the difference between the two.

 

Question: 

What is the difference between "Interval Counter" and "Counter" metrics, with regard to calculators ?

 

Environment:  

All Introscope environments.

 

Answer: 

Counter = a value that is usually incremented/decremented by tracers, and retains its value across interval boundaries, e.g.- A database connection count.

Interval counter = a value that starts from 0 each interval, and is only incremented, e.g.- responses per interval

 

Additional Information:

For a calculator, since the value is recalculated for each interval, the type of the metric makes no difference.
