IT37825: PERFORMANCE COLLECTION INTERVAL IS LESS THAN FIVE MINUTES AND TWO CONSECUTIVE INTERVALS CONTAIN THE SAME STATISTICAL FILES

APAR status

• Closed as program error.

Error description

• Performance metrics have a zero value in some cases and the
  performance collection interval is less than five minutes.
  Looking at two consecutive performance collection jobs, the same
  statistical data is collected.
  
  When viewing the performance graphs for storage devices, this
  may appear as random drops of I/O activity to 0.  The zero
  values and the discrepancies in the interval length are also
  seen in the output from Export Performance Data.
