Method Detail

getClusterName

java.lang.String getClusterName()

Returns the full name of the cluster. For example, rcas.rcf.bnl.gov

getLoad1m

double getLoad1m()

Cumulative load of the cluster in the past minute. This is the sum of the load of all the machines in the cluster

getLoad5m

double getLoad5m()

Cumulative load of the cluster in the past five minutes. This is the sum of the load of all the machines in the cluster

getCPUCount

int getCPUCount()

Number of CPUs in the cluster. A machine with two processors counts 2.

getAverageLoad1m

double getAverageLoad1m()

Average load of the cluster in the past minute. This equal to cumulative load divided by CPUCount.

getAverageLoad5m

double getAverageLoad5m()

Average load of the cluster in the past five minutes. This equal to cumulative load divided by CPUCount.
