Cluster Health Score
The health score starts at 100. Penalties reduce the score. There are three penalty types:
SevereErrorPenalty = 50
ErrorPenalty = 15
WarningPenalty = 3
WarningPenalty is applied when:
- Single Cluster (Master exists on Cluster - for kops based kubernetes deployments on AWS)
- Single Region
- Predictive Disk Growth crosses a 90% threshold
ErrorPenalty is applied:
- Any Nodes in the Cluster are Not Ready
- Any Nodes are under MemoryPressure
SevereErrorPenalty is applied:
- Memory Usage exceeds 90% of Available Memory on the Cluster
The Cluster Health alert is based on a threshold of change. For example, an alert on 14 would alert anytime an Error penalty was applied.
