Measures reported by VrtxPowerSupplyTest
Each power supply unit in the VRTX will contain multiple power supply points. The availability and proper functioning of each of these ppower supply points is critical to the uninterrupted operations of the VRTX. Irrecoverable errors, sensor failures, or erratic voltage fluctuations experienced by a power point can stall VRTX operations for hours, slowing down or completely suspending the delivery of the dependent business services. If such an unpleasant eventuality is to be pre-empted, administrators must be able to proactively detect potential problems with a power supply point and take remedial action before anything untoward happens. The VrtxPowerSupplyTest test helps administrators achieve this end.
For each power supply point on the VRTX, this test reports how healthy that power supply point currently is, how well (or badly) its sensor is performing currently, and what is that power supply's current voltage. In the process, administrators can quickly isolate those power supply points that are behaving abnormally and can immediately initiate measures to correct the anomaly.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Health_status |
Indicates how healthy this power supply point currently is. |

The values that this measure can report and their corresponding numeric values are discussed below:
| Measure Value |
Numeric Value |
| Other |
1 |
| Unknown |
2 |
| Normal |
3 |
| NonCritical |
4 |
| Critical |
5 |
| NonRecoverable |
6 |
Note:
By default, this measure reports one of the Measure Values listed above to indicate the current health of a power supply point. In the graph of this measure however, the same is represented using the numeric equivalents only. |
| Sensor_status |
Indicates the current operational state of this power supply's sensor. |

Note:
By default, this measure reports one of the Measure Values listed above to indicate the current health of a power supply's sensor. In the graph of this measure however, the same is represented using the numeric equivalents only. |
| Input_voltage |
Indicates the current input voltage of this power supply. |
Volts |
A sudden and significant spike in the value of this measure could prove to be detrimental to the health of the power supply point and other internal components of the VRTX. |
