Show Device Performance
Shows performance metrics for one or more persistent memory modules.
ipmctl show [OPTIONS] -performance [METRICS] [TARGETS]
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.
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.
Show all performance metrics for all modules in the server
$ ipmctl show -dimm -performance
Show the number of 64 byte reads since last AC cycle for all modules in the server
$ ipmctl show -dimm -performance MediaReads
