Logical Disk Avg. Disk sec/Transfer

Microsoft.Solaris.11.LogicalDisk.AverageDiskTransferTime.Monitor (UnitMonitor)

Solaris 11 Logical Disk Avg. Disk sec/Transfer Monitor

Knowledge Base article:

Summary

The average time per transfer for the logical disk (file system) is high. System performance may be adversely affected.

This average time per transfer is measured in seconds.

The monitor threshold is analyzed against an average of values returned in polls to the agent, where the Number of Samples parameter controls the number of samples included in the calculation of the average. The value returned by the agent is the average rate for the preceding 5 minutes. This metric is not implemented for agents installed in a non-global zone.
