Metrics
Shows output of a specific performance metric by supplying the metric name. See RETURN DATA for more information. One of:
MediaReads: Number of 64 byte reads from media on the module since last AC cycle.MediaWrites: Number of 64 byte writes to media on the module since last AC cycle.ReadRequests: Number of DDRT read transactions the module has serviced since last AC cycle.WriteRequests: Number of DDRT write transactions the module has serviced since last AC cycle.TotalMediaReads: Number of 64 byte reads from media on the module over its lifetime.TotalMediaWrites: Number of 64 byte writes to media on the module over its lifetime.TotalReadRequests: Number of DDRT read transactions the module has serviced over its lifetime.TotalWriteRequests: Number of DDRT write transactions the module has serviced over its lifetime.
The default is to display all performance metrics.
Targets
dimm (DimmIDs): Show the performance metrics of specific modules by supplying one or more comma-separated DimmIDs. The default is to display sensors for all manageable modules.
