Measures reported by IBMChasFuelGugeTest
To manage the power consumption of the components of the target chassis and provide power redundancy during failures, administrators create two power domains using the advanced management module Web interface. Each power domain is allocated with a specific amount of power which will be shared among the chassis components. The chassis components in each power domain are grouped based on their types and estimated power consumption. The power domains should be able to supply the adequate amount of power to power-on and ensure smooth functioning of the chassis components such as blade servers. If the power domains run out of the allocated power, the chassis components may start to malfunction or shut-down completely, which in turn stalls the operations of the target chassis. To avoid such eventualities, administrators should be alerted to the power shortage immediately before the chassis operations shut down. This can be easily done using the Fuel Gauge test!
This test auto-discovers the power domains on the target chassis and for each power domain, reports the current status and power utilization, thus turning the spotlight on the power domain that is being over-utilized.
Outputs of the test : One set of results for each power domain in the BladeCenter chassis being monitored.
Descriptor of the test : Power Domain
The measures made by this test are as follows:

The values that this measure can report and the numeric values they indicate have been listed in the table below:
| Measure Value |

| Good |
1 |
| Warning |
2 |
| Bad |
3 |
Note: By default, this measure can report the Measure Values mentioned above while indicating the current status of each power domain. However, the graph of this measure is indicated using the numeric equivalents. |
| Total_avail_pwr |
Indicates the total amount of power that is available in this power domain. |
Watts |
Total power is calculated by the management module according to the rated capacities of the power modules that are installed in each power domain and the power-management policy that has been set for each power domain. |
| Reserved_pwr |
Indicates the amount of power reserved for use by the components in this power domain. |
Watts |
|
| Avail_remain_pwr |
Indicates the amount of power that is available for use in this power domain. |
Watts |
The value of this measure is calculated according to the Total available power and the Reserved power measures for each power domain. |
| Power_used |
Indicates the amount of power that is being used in this power domain. |
Watts |
If the value of this measure is close to the value of the Total available power measure, it is a cause for a concern.
Comparing the value of this measure across the power domains can help you instantly identify the power domain that is being over-utilized. |
| pct_free_power |
Indicates the percentage of power that is available for use in this power domain. |
