Network UPS Tools is a collection of programs which provide a common
|
|
|
|
|
interface for monitoring and administering Uninterruptible Power
|
|
|
|
|
Supply (UPS), Power Distribution Unit (PDU), and Solar Controller
|
|
|
|
|
Device (SCD) hardware. It uses a layered approach to connect all
|
|
|
|
|
of the parts.
|
|
|
|
|
|
|
|
|
|
Drivers are provided for a wide assortment of equipment. They
|
|
|
|
|
understand the specific language of each device and map it back to
|
|
|
|
|
a compatibility layer. This means both an expensive high end UPS,
|
|
|
|
|
a simple "power strip" PDU, or any other power device can be handled
|
|
|
|
|
transparently with a uniform management interface.

|
This information is cached by the network server upsd, which then
|
|
|
|
|
answers queries from the clients. upsd contains a number of access
|
|
|
|
|
control features to limit the abilities of the clients. Only
|
|
|
|
|
authorized hosts may monitor or control your hardware if you wish.
|
|
|
|
|
Since the notion of monitoring over the network is built into the
|
|
|
|
|
software, you can hang many systems off one large UPS, and they
|
|
|
|
|
will all shut down together. You can also use NUT to power on, off
|
|
|
|
|
or cycle your data center nodes, individually or globally through
|
|
|
|
|
PDU outlets.
