View Cluster Health APIs

GET /api/v2.2/clusters/(string:id or label)/live_cluster_health

Use this API to view the latest health of a running cluster in a Qubole environment. It is supported with QDS version R57 onwards. It is supported in Cluster API v1.3, v2.0, and v2.2.

Required Role

Users belong to a group that has permission to read a cluster required to invoke this API.

Request API Syntax

curl -i -X GET -H "X-AUTH-TOKEN: $AUTH_TOKEN" -H "Content-Type: application/json" -H "Accept: application/json"
"https://api.qubole.com/api/v2.2/clusters/<cluster_id>/live_cluster_health

As the value of <Qubole Environment>, use the Qubole environment where you have the QDS account. For example, https://api.qubole.com is a Qubole environment.

Note

The above syntax uses cluster v2 and the response below are for the cluster API version 2.0.
