Avg. Disk sec/Write (SUSE Linux Enterprise Server 12)

Microsoft.Linux.SLES.12.PhysicalDisk.AverageDiskWriteTime.Collection (Rule)

Collection rule for the performance counter Physical Disk\Avg. Disk sec/Write

Knowledge Base article:

Summary

This rule collects performance data for the Physical Disk\Avg. Disk sec/Write performance counter. The collected values are accessible in performance views and reports.

This metric exposes the average time, in seconds, of disk writes. A disk that is developing a bottleneck might cause the entire system to slow.

The value returned by the agent is the average rate for the preceding 5 minutes.

Monitoring of physical disks is disabled by default. Enable monitoring by enabling the object discovery named 'Discover SUSE Linux Enterprise Server 12 Physical Disks.'
