Method Detail

getClusterTime

long getClusterTime()

Returns the cluster-time in milliseconds. The cluster-time measures elapsed time since the cluster was created. Comparable to the System.nanoTime().

Returns:

the cluster-time (elapsed milliseconds since the cluster was created).

getClusterUpTime

long getClusterUpTime()

Returns the cluster up-time in milliseconds. When first node in cluster becomes master, its clusterTime value is saved as clusterStartTime. Up-time of cluster is calculated as ClusterClock#getClusterTime - clusterStartTime.

Returns:

the cluster-up-time
