Cluster Metrics

VMware Aria Operations
collects metrics for the
VMware Aria Operations
cluster objects including dynamic threshold calculation metrics and capacity computation metrics.
Metrics can be calculated for cluster objects. See Calculated Metrics.

Cluster Metrics

Cluster metrics provide host, resource, and metric counts on the cluster.

Count (VM)
Usage Count
This metric displays how many units of the license capacity is currently used.
License Metrics for Cluster Object
Used (VM)
Usage (%)
This metric displays the percentage of the total license capacity currently used.
An alert is generated if the license threshold is in any of the following states:
  • >= 80% - Warning
  • >= 90% - Immediate
  • =95% - Catastrophic
Days Remaining (day)
Days Remaining
This metric displays the days remaining before the license expires.
Capacity
Capacity
Displays the maximum number of units (of the given capacity type) that can be licensed by this license key.
Type
Type
Displays the license type for the cluster object.
Expiry
Expiration Date
Displays the date when the license expires.
Capacity
Capacity
Displays the maximum number of units (of the given capacity type) that can be licensed by this license key.
Disbalance factor (%)
Disbalance factor (%)
Identifies the state of disbalance in a
VMware Aria Operations
cluster and calculates the disbalance factor (when one or more nodes have a higher density among all the nodes in the cluster). Based on the disbalance percentage of the node, the following alerts are triggered:
  • Warning: If the disbalance factor metric is equal to or greater than 5%.
  • Immediate: If the disbalance factor metric is equal to or greater than 7%.
  • Critical: If the disbalance factor metric is equal to or greater than 10%.

DT Metrics

DT metrics are dynamic threshold metrics for the cluster. Non-zero values appear only if metric collection occurs while the dynamic threshold calculations are running.
