MBean Instances on the Master Node

One instance of each of the following MBeans is instantiated on the master node of the cluster.

  • CmmMasterNodeMBean

  • CmmMasterStatisticsMBean

  • RnfsMasterStatisticsMBean

  • PmdMasterStatisticsMBean

  • CgtpMasterMBean

An RnfsReplicatedSliceMBean is instantiated on the master node and on the vice-master node for each Reliable NFS partition.

MBean Instances on Peer Nodes

One instance of each of the following MBeans is instantiated on each peer node of the cluster:

  • ClusterNodeMBean

  • CmmStatisticsMBean

  • RnfsStatisticsMBean

  • PmdStatisticsMBean

  • CgtpMBean

  • CgtpFilterMBean

Multiple instances of the following MBeans might be instantiated:

CgtpReliableLinkStatisticsMBean

One instance for each reliable link.

PmdNameTagStatisticsMBean

One instance for each group of processes monitored by the Daemon Monitor.

Floating External Address

An external Java manager can use the floating external address (for example, 10.250.10.1) to communicate with the master node. After failover and switchover the floating address is reassigned to the new master node. The external Java manager must then connect to the new master node, but can connect to the same IP address as before. SNMP cannot use the floating external address to communicate with the master node.
