Error description

• Environment: The Monitoring Agent for UNIX OS 6.2.2 on Solaris
  
  
  Problem Description: On Solaris the Monitoring Agent for UNIX OS
          can collect negative values for performance information
          when it detects a new NFS disk for the first time.
          This issue seems to be due to a bug/strange behavior in
          Solaris kstat API. ITM code is going to be changed in
          order to verify that collected data are not negative
          before storing them in its internal cache.
  

Local fix

• N/A
  

Problem summary

• On Solaris, the Monitoring Agent for UNIX OS can collect
  negative values for performance information when it detects a
  new NFS disk. This issue is caused by an anomaly in the Solaris
  kstat interface.
  

Problem conclusion

• The behavior of the agent has changed to verify that data
  collected is not negative.
  
  
  The fix for this APAR is going to be included in the following
  maintenance vehicle:
