Clustered Data ONTAP Virtualization: Virtual Hard Disk LUN Space Utilization (\%) Monitor

DataONTAP.Cluster.Virtualization.HyperV.VhdOnLUN.LUNUsedSpaceMonitor (UnitMonitor)

The Virtual Hard Disk LUN Space Utilization (\%) Monitor monitors the value of the LUN Space Utilization counter collected by the Virtual Hard Disk LUN Monitoring Rule.

Knowledge Base article:

Summary

The Virtual Hard Disk LUN Space Utilization (%) Monitor monitors the value of the LUN Space Utilization counter collected by the Virtual Hard Disk LUN Monitoring Rule:

Counter Name: LUN Space Utilization

Instance Name: LUN Used Space (%)

Space utilization is defined as the percentage of the total space that has been used on the LUN.

Configuration

Two overrides are available for this monitor. Lower Threshold and Upper Threshold set the space utilization threshold percentages that trigger alerts.

The default lower threshold is 90%. Any value less than or equal to the lower threshold triggers a critical alert.

The default upper threshold is 95%. Any value between the lower and upper thresholds triggers a warning alert.
