getClusterStatus

Syntax

getClusterStatus(clusterName)

Arguments

clusterName is a STRING scalar or vector, indicating the name of the cluster.

Details

Return the status of a specified cluster. This function can only be executed by an administrator on the MoM (Master of Masters) cluster.

Return value: A table. Except for the “clusterName” and ”computeGroup” columns, all other fields are consistent with the result of the getClusterPerf:

  • clusterName: Name of the cluster.
  • computeGroup: Name of the compute group. If there are no compute group in the cluster, this field will be empty.
