Unhealthy AZ Threshold

If there are more nodes in the not ready state than the specified value of this parameter in a given AZ, this AZ will be treated as unhealthy.

When more than a certain proportion of pods in an AZ are unhealthy, the AZ itself will be considered unhealthy, and scheduling pods to nodes in that AZ will be restricted to limit the impacts of the unhealthy AZ.

Value Range

Greater than 0 and less than 1

Default Value

0.55

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

Unless otherwise specified, keep the default settings.

If the parameter is set to a large value, pods in the unhealthy AZs will be migrated in a large scale, which may lead to risks such as overloaded clusters.
