  1. Instrumentation

Show Device Performance

Shows performance metrics for one or more persistent memory modules.

ipmctl show [OPTIONS] -performance [METRICS] [TARGETS]

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.

Examples

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
