Index Count Condition

This condition counts the number of indices assigned to a configured alias. If the number exceeds the configured maximum, this condition triggers if the current index is the oldest.

To determent which alias to check this condition requires an alias key configured in the index.aim.alias_mapping part of the index settings.

Index Settings Example

{
  "index.aim.policy_name": "my-policy",
  "index.aim.alias_mapping": {
    "my-size-condition-key": "my-alias"
  }
}
