WebSphere MQ - Guilty until proven innocent

Greetings!

Often the product I represent at work, WebSphere MQ, is assumed to be the culprit for every slow down or perceived outage.  This is often because the first observed symptom is either an increasing queue depth, or a report of 'messages getting lost.' There are times when WMQ does have a problem or fault, but far more often the underlying cause is a resource constraint, a network problem, or an application slowdown. 

One of my customers at SHARE told me that they have a term for all the problem investigation time they spend discovering that it's NOT the fault of WMQ; 'mean time to innocence.'  

Happy Thursday!
