To check the current convergence status of a Rhino cluster use the following rhino-console commands or associated MBean operation:

Console command: isconverged

Command

 
isconverged [-nodes node1,node2,...]
  Description
    Check if Rhino's actual state is currently equal to desired state.  If a node
    list is provided, only the specified nodes are checked.

Examples

To check if the actual states of all components match the desired states:

$ ./rhino-console isconverged
Rhino is currently converged to desired state

To check if the actual states of all components match the desired states on node 101:

$ ./rhino-console isconverged -nodes 101
Node [101] is currently converged to desired state

Console command: waittilconverged

Command

 
waittilconverged [-timeout timeout]
  Description
    Wait for actual state to converge to desired state. The optional timeout is
    specified in seconds

Example

To wait for up to one minute for the actual states of all components to match the desired states:

$ ./rhino-console waittilconverged -timeout 60
Covergence reached. Actual state has converged to desired state.

MBean operation: isConvergedToDesiredState

MBean

Config Management

Rhino operations

 
public boolean isConvergedToDesiredState()
    throws ManagementException;

public boolean isConvergedToDesiredState(int[] nodes)
    throws ManagementException;

These operations return true if the actual state of all components in all namespaces matches the desired state. The first method checks all event router nodes in the cluster. The second method only checks the specified cluster nodes.
