Physical Disk Overview (PI_PDSK)

Function

The Physical Disk Overview (PI_PDSK) record stores performance data, taken at a specific interval, about physical disks on the monitored host. This is a multi-instance record.

Notes

• If the connection to the monitored host fails, the information cannot be collected.
• If the OS of the monitored host is AIX, only the following users can collect this record information:
  
  • root user
  • User who belongs to both adm and system groups

Default and changeable values

Item	Default value	Changeable
Collection Interval	300	Y
Collection Offset	0	Y
Log	No	Y
LOGIF	(Blank)	Y

Record size

• Fixed part: 1,034 bytes
• Variable part: 652 bytes
