Class ShardsCapacityHealthIndicatorService

java.lang.Object

org.elasticsearch.health.node.ShardsCapacityHealthIndicatorService

All Implemented Interfaces:

HealthIndicatorService

public class ShardsCapacityHealthIndicatorService
extends Object
implements HealthIndicatorService

This indicator reports health data about the shard capacity across the cluster. The indicator will report:

• RED when there's room for less than the configured health.shard_capacity.unhealthy_threshold.red (default 5) shards (either data or frozen nodes)
• YELLOW when there's room for less than the configured health.shard_capacity.unhealthy_threshold.yellow (default 10) shards (either data or frozen nodes)
• GREEN otherwise

Although the `max_shard_per_node(.frozen)?` information is scoped by Node, we use the information from master because there is where the available room for new shards is checked before creating new indices.
