Subject How does ActiveMQ compute statistics exposed though JMX
Date Thu, 26 Apr 2012 13:42:14 GMT
Hello,

I am a little confused about some properties (AverageEnqueueTime,
MaxEnqueueTimethat,
MinEnqueueTime) that are exposed via JMX.

Are these properties are computed ?

this is a brief extract of values :
[ ]
date AverageEnqueueTime MaxEnqueueTime MinEnqueueTime
02/04/2012 12:35 0,300976 4246 0
02/04/2012 12:35 0,249668 175 0

It does not seem that the MaxEnqueueTime is absolute because it changes too
much.
Are they computed on per time basis ? which one ?

and sometimes the min is greater than the average. It is crazy.

What am I missing ?

thanks for your help.
