Monitoring Power Supply

The power supply is the component that transforms the AC Line into electric power needed by the computer. Therefore the power supply is a highly critical device of a computer that should never fail. Due to this, many vendors build servers with redundant power supplies. Monitoring power supplies allows the operators to be alerted when a power supply fails, or in some cases even when a power supply is overloaded.

Depending on the available information, the UsedCapacity and/or Status parameters will be displayed for each power supply or power unit device:

•	The UsedCapacity parameter represents the power currently in use as a percentage. An alert is triggered when the power supply’s maximum power output is reached.

•	The Status parameter represents the current status of the power supply. An alert is triggered if an error occurs with the power supply.
