Public Property MaxPercentUnhealthyNodes As Byte

Property Value

Byte

The maximum allowed percentage of unhealthy nodes. Allowed values are integer values from zero to 100.

Exceptions

ArgumentOutOfRangeException

The specified value was outside the range of integer values from zero to 100.

Remarks

The percentage represents the maximum tolerated percentage of nodes that can be unhealthy before the cluster is considered in error. If the percentage is respected but there is at least one unhealthy node, the health is evaluated as Warning. This is calculated by dividing the number of unhealthy nodes over the total number of nodes in the cluster. The computation rounds up to tolerate one failure on small numbers of nodes. Default percentage: zero.

In large clusters, some nodes will always be down or out for repairs, so this percentage should be configured to tolerate that.
