Show Sensor

Shows health statistics for one or more persistent memory modules.

$ ipmctl show [OPTIONS] -sensor [SENSORS] [TARGETS]

Sensors

• Health: The current module health as reported in the SMART log

• MediaTemperature: The current module media temperature in Celsius

• ControllerTemperature: The current module controller temperature in Celsius

• PercentageRemaining: Remaining module life as a percentage value of factory expected life span

• LatchedDirtyShutdownCount: The number of shutdowns without notification over the lifetime of the module

• Unlatched DirtyShutdownCount: The number of shutdowns without notification over the lifetime of the module. This counter is the same as LatchedDirtyShutdownCount except it will always be incremented on a dirty shutdown, even if Latch System Shutdown Status was not enabled.

• PowerOnTime: The total power-on time over the lifetime of the module

• UpTime: The total power-on time since the last power cycle of the module

• PowerCycles: The number of power cycles over the lifetime of the module

• FwErrorCount: The total number of firmware error log entries

Targets

• dimm (DimmIDs): Show only the sensors on specific modules by supplying the DIMM target and one or more comma-separated DimmIDs. The default is to display sensors for all manageable modules.

Examples

Get all sensor information for all modules

$ ipmctl show -sensor

Show the media temperature sensor for the specified module

$ ipmctl show -sensor MediaTemperature -dimm 0x0011

Return Data

• DimmID: The persistent memory module identifier

• Type: The sensor type. Refer to the Sensors list above

• CurrentValue: The current reading followed by the units of measurement (e.g., 57 °C or 25%)

• CurrentState: The current value in relation to the threshold settings (if supported). One of:

  • Unknown: The state cannot be determined

  • Normal: The current reading is within the normal range. This is the default when the sensor does not support thresholds

  • NonCritical: The current reading is within the non-critical range. For example, an alarm threshold has been reached

  • Critical: The current reading is within the critical range. For example, the firmware has begun throttling down traffic to the persistent memory module due to the temperature

  • Fatal: The current reading is within the fatal range. For example, the firmware is shutting down the module due to the temperature

• LowerThresholdNonCritical: The threshold value below which the state is considered "NonCritical".

• UpperThresholdNonCritical: The threshold value at or above which the state is considered "NonCritical".

• LowerThresholdCritical: The threshold value below which the state is considered "Critical".

• UpperThresholdCritical: The threshold value at or above which the state is considered "Critical".

• UpperThresholdFatal: The threshold value at or above which the state is considered "Fatal".

• SettableThresholds: A list of user settable thresholds. Zero or more of:

  • LowerThresholdNonCritical

  • UpperThresholdNonCritical

• SupportedThresholds: A list of supported thresholds. Zero or more of:

  • LowerThresholdNonCritical

  • UpperThresholdNonCritical

  • LowerThresholdCritical

  • UpperThresholdCritical

  • UpperThresholdFatal

• EnabledState: Whether the critical threshold alarm is enabled, disabled or not applicable. One of:

  • 0: Disabled

  • 1: Enabled

  • N/A
