Get autoscaling capacity API
editGet autoscaling capacity API
editThis feature is designed for indirect use by Elasticsearch Service, Elastic Cloud Enterprise, and Elastic Cloud on Kubernetes. Direct use is not supported.
Get autoscaling capacity.
Request
editresp = client.autoscaling.get_autoscaling_capacity() print(resp)
const response = await client.autoscaling.getAutoscalingCapacity(); console.log(response);
GET /_autoscaling/capacity/
Prerequisites
edit-
If the Elasticsearch security features are enabled, you must have
manage_autoscalingcluster privileges. For more information, see Security privileges.
Description
editThis API gets the current autoscaling capacity based on the configured autoscaling policy. This API will return information to size the cluster appropriately to the current workload.
The required_capacity is calculated as the max of the required_capacity
result of all individual deciders that are enabled for the policy.
The operator should verify that the current_nodes match
the operator’s knowledge of the cluster to avoid making autoscaling decisions
based on stale or incomplete information.
The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only. Do not use this information to make autoscaling decisions.
Query parameters
edit-
master_timeout -
(Optional, time units)
Period to wait for the master node. If the master node is not available before
the timeout expires, the request fails and returns an error. Defaults to
30s. Can also be set to-1to indicate that the request should never timeout.

Examples
editThis example retrieves the current autoscaling capacity.
resp = client.autoscaling.get_autoscaling_capacity() print(resp)
const response = await client.autoscaling.getAutoscalingCapacity(); console.log(response);
GET /_autoscaling/capacity
The API returns the following result:
{
policies: {}
}
