=head3 start
This function gets called by the monitorctrl module
when xcatd starts. It starts the daemons and does
necessary startup process for the RMC monitoring.
It also queries the RMC for its currently monitored
nodes which will, in tern, compared with the nodes
in the input parameter. It asks RMC to add or delete
nodes according to the comparison so that the nodes
monitored by RMC are in sync with the nodes currently
in the xCAT cluster.
Arguments:
None.
Returns:
(return code, message)

rmcmon uses IBM's Resource Monitoring and Control (RMC) component
of Reliable Scalable Cluster Technology (RSCT) to monitor the

process, network, file system etc for monitoring. RMC can also be
used to provide node liveness status monitoring for xCAT. RMC is
good for threadhold monitoring. xCAT automatically sets up the
monitoring domain for RMC during node deployment time. To start
