Problem summary

Problem conclusion

Temporary fix

Comments

• FlashSystem returns invalid performance counters: previous
  ones greater than the current ones.
  
  These invalid metrics returned from the device result in
  the performance data gaps seen in Spectrum Control
  and Storage Insights.
