Error description

• Environment:
  The Monitoring Agent for UNIX OS 6.2.2 on Solaris
  
  Problem Description:
  On Solaris the Monitoring Agent for UNIX OS stat_daemon and
  kuxdstat processes can generate high CPU usage if it monitors a
  Veritas Dynamic Multipathing with thousands of disks. In order
  to avoid this issue a configuration key to disable this kind of
  datacollection is required.
  

Local fix

Problem summary

• On Solaris, the monitoring agent for UNIX OS stat_daemon and
  kuxdstat processes can generate high CPU usage if they monitors
  a Veritas Dynamic Multipathing with thousands of disks. In order
  to avoid this issue, a configuration variable to disable
  collecting disk information has been created.
  

Problem conclusion

• Added variable KUX_DISABLE_UNIXDPERF to disable disk
  performance data collection. The default value is FALSE, but it
  can be enabled by setting it to TRUE in the ux.ini file, and
  restarting the agent.
