As a performance consultant I used to think it was only me that needed to glean configuration information from performance data - because I didn't want to ask foolish questions of the customer.
But gradually (it seems to me) customers have ended up in the same boat as me:
The utter complexity of machine configurations and settings - whether z/OS, or DB2, or CICS, or Websphere, or MQ, or ... - means that it's increasingly difficult to check that things are as we thought they were.
I'm not asking anyone to declare themselves
Because that's an argument I'm increasingly using with Development groups.
Most such groups do a good job, whether it's DB2 providing its dynamic settings in a Statistics Trace record, or the wealth of configuration information in RMF. There are however some untidinesses that I'm working to see fixed.
