This information is transient in nature and used (exclusively?) by the PolicyEngine[1] in its calculations of the next stable state of the cluster.
It contains cluster status information grouped by node[2]. This information includes:
Resources running (according to the LocalResourceManager[3])
This information is solicited from all ClusterNodes[4] when the DesignatedCoordinator[5] is first elected and when new ClusterNodes[4] complete as part of the JoinProtocol[6].
