Synopsis

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

Description

Shows performance metrics for one or more PMem modules.

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:

The default is to display all performance metrics.

Targets

-dimm [DimmIDs]

Restricts output to the performance metrics for specific PMem module by supplying one or more comma separated PMem module identifiers. The default is to display performance metrics for all manageable PMem module.

Examples

Shows all performance metrics for all PMem modules in the server.

ipmctl show -dimm -performance

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

ipmctl show -dimm -performance MediaReads

Limitations

In order to successfully execute this command:

Return Data

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

DimmID

The PMem module identifier

MediaReads

Number of 64 byte reads from media on the PMem module since last AC cycle.

MediaWrites

Number of 64 byte writes to media on the PMem module since last AC cycle.

ReadRequests

Number of DDRT read transactions the PMem module has serviced since last AC cycle.

WriteRequests

Number of DDRT write transactions the PMem module has serviced since last AC cycle.

TotalMediaReads

Number of 64 byte reads from media on the PMem module over its lifetime.

TotalMediaWrites

Number of 64 byte writes to media on the PMem module over its lifetime.

TotalReadRequest

Number of DDRT read transactions the PMem module has serviced over its lifetime.

TotalWriteRequest

Number of DDRT write transactions the PMem module has serviced over its lifetime.
