eG Help

The Fuel Gauge component in Lenovo XCalrity Controller is to manage the power supply for the server or group of servers managed by XClarity Controller. It controls server power usage and configure server power management. Fuel Gauge can be accessed from XClarity Command Line INterface (CLI) using command fuelg. You can control various important power management function using fuel gauge like enable/disable power management and capping on the server, set the power capping mode, get power consumption and performance history, set policy mode for loss of redundant power, get current power consumption etc.

Given that fuel gauge controls the entire power supply to controller and the server, it is really important to monitor the Fuel Gauge so that any issue with it can be investigated and understood at the earliest and fixed before the server power supply is affected.

This test auto discovers the Fuel Gauge and reports key statistics like current power usage by controller, remaining power, CPU and memory consumption etc.

Measurement	Description	Measurement Unit	Interpretation
powerUse	Indicates the total power in use by controller during the last measurement period.	mA	The value of total power in use should be within the operating range, if it is out the range over multiple measurements there may be some issue with controller.
powerAvail	Indicates the total power available with the controller during the last measurement period.	mA	Available power is a good indicator of health of controller.
powerRem	Indicates the total power available with the controller during the last measurement period.	mA	Adequate power remaining is the indicator of efficient functioning of controller, if it is not adequate, you need to look into it.
cpuPower	Indicates the amount of power being consumed by controller CPU during the last measurement period.	mA	Gives a clear indication of where the power is being consumed, if it is CPU, Memory or other entities. Anywhere if you feel the consumption is more than expected, you can start investigating.
memPower	Indicates the amount of power being consumed by controller memory during the last measurement period.	mA	Gives a clear indication of where the power is being consumed, if it is CPU, Memory or other entities. Anywhere if you feel the consumption is more than expected, you can start investigating.
othrPower	Indicates the amount of power being consumed by other entities in the controller during the last measurement period.	mA	Gives a clear indication of where the power is being consumed, if it is CPU, Memory or other entities. Anywhere if you feel the consumption is more than expected, you can start investigating.
