NAME

       ipmctl-show-performance - Shows performance metrics for one or more DCPMMs

SYNOPSIS

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

DESCRIPTION

       Shows performance metrics for one or more DCPMMs.

OPTIONS

       -h, -help
           Displays help for the command.

       -ddrt
           Used to specify DDRT as the desired transport protocol for the current invocation of ipmctl.

       -smbus
           Used to specify SMBUS as the desired transport protocol for the current invocation of ipmctl.

           Note
           The -ddrt and -smbus options are mutually exclusive and may not be used together.

       -o (text|nvmxml), -output (text|nvmxml)
           Changes the output format. One of: "text" (default) or "nvmxml".

METRICS

       Restricts output to a specific performance metric by supplying the metric name. See RETURN DATA for more
       information. One of:

       •   MediaReads

       •   MediaWrites

       •   ReadRequests

       •   WriteRequests

       •   TotalMediaReads

       •   TotalMediaWrites

       •   TotalReadRequests

       •   TotalWriteRequests

       The default is to display all performance metrics.

TARGETS

       -dimm [DimmIDs]
           Restricts output to the performance metrics for specific DCPMM by supplying one or more comma
           separated DCPMM identifiers. The default is to display performance metrics for all manageable DCPMM.

EXAMPLES

       Shows all performance metrics for all DCPMMs in the server.

       ipmctl show -dimm -performance

       Shows the number of 64 byte reads since last AC cycle for all DCPMMs in the server.

       ipmctl show -dimm -performance MediaReads

LIMITATIONS

       In order to successfully execute this command:

       •   The caller must have the appropriate privileges.

       •   The specified DCPMM(s) must be manageable by the host software.

RETURN DATA

       This command displays a table of the specified metrics for each specified DCPMM. Applying a specific
       DCPMM target limits the rows in the table. Applying a specific metric name target limits the columns in
       the table.

       DimmID
           The DCPMM identifier

       MediaReads
           Number of 64 byte reads from media on the DCPMM since last AC cycle.

       MediaWrites
           Number of 64 byte writes to media on the DCPMM since last AC cycle.

       ReadRequests
           Number of DDRT read transactions the DCPMM has serviced since last AC cycle.

       WriteRequests
           Number of DDRT write transactions the DCPMM has serviced since last AC cycle.

       TotalMediaReads
           Number of 64 byte reads from media on the DCPMM over its lifetime.

       TotalMediaWrites
           Number of 64 byte writes to media on the DCPMM over its lifetime.

       TotalReadRequest
           Number of DDRT read transactions the DCPMM has serviced over its lifetime.

       TotalWriteRequest
           Number of DDRT write transactions the DCPMM has serviced over its lifetime.
