How can we check I/O skewed processing for a query?

Hi All,
 
While inserting records into a target table from source table using Bteq utility, I faced an error message like below, thus aborting the session.
 *** Failure 3156 Request aborted by TDWM. Exception criteria exceeded:   AMP CPU Skew, AMP I/O Skew.

Hi ,
Can some please explain / eloborate the DBQL Metrics and how they are interrelated like the below with some example with any record count
TotalIOCount,
MaxAmpIO,
MaxAmpCPU,
ImpactCPU
ImpactIO,
CPUSKew,
IOSkew,
IOSkewWastage,
CPUSkewWastage
 
Thanks
