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 and performance monitoring for xCAT. RMC is good for threadhold monitoring. xCAT automatically sets up the monitoring domain for RMC during node deployment time. And if performance monitoring is enabled, xCAT monitoring will collect and consolidate performance data based on montype&rmetrics setting, and then store to RRD database. Settings: rfanout -- indicating the fanout number for configuring or deconfiguring remote nodes. nodeusebatch -- use RMC event batching function when doing node status monitoring. montype -- indicating type of performance monitoring, the value could be \"event\" : event monitoring (default), \"perf\" : performance monitoring, \"event,perf\" or \"perf,event\" : both. rmetrics -- defines resource class,resouce names, attributes and sample interval for performance monitoring. Syntax of key: rmetrics_resource class For example: rmetrics_IBM.Processor Syntax of value: [resource names]attribute names:sample interval The unit of sample interval is minute.
