=head3 start
|
|
This function gets called by the monitorctrl module
|
|
when xcatd starts and when monstart command is issued by the user.
|
|
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.
|
|
p_nodes -- a pointer to an arrays of nodes to be monitored. null means all.
|
|
scope -- the action scope, it indicates the node type the action will take place.
|
|
0 means localhost only.
|
|
2 means both localhost and nodes,
|
|
callback -- the callback pointer for error and status displaying. It can be null.
|
|
Returns:
|
|
(return code, message)
|
|
if the callback is set, use callback to display the status and error.

rmcmon uses IBM's Resource Monitoring and Control (RMC) component
|
|
of Reliable Scalable Cluster Technology (RSCT) to monitor the
|
|
xCAT cluster. RMC has built-in resources such as CPU, memory,
|
|
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.
