Enter the Name of the particular remote UPS that you want to remotely monitor. This name must be the name that the remote UPS was configured with on the remote console server (because the remote console server may itself have multiple UPSes attached that it manages locally with NUT). Optionally, enter a Description.

Enter the IP Address or DNS name of the remote console server* that is managing the remote UPS. (*This may be another Black Box console server or it may be a generic Linux server running Network UPS Tools.)

Note An example where centrally monitor remotely distributed UPSes is useful is a campus or large business site where there’s a multitude of computer and other equipment sites spread afar, each with their own UPS supply … and many of these (particularly the smaller sites) will be USB or serially connected.

Having a console server at these remote sites would enable the system manager to centrally monitor the status of the power supplies at all sites, and centralize alarms. So he/she can be warned to initiate a call-out or shut-down.

Check Log Status and specify the Log Rate (minutes between samples) if you want the status from this UPS to be logged. You can view these logs from the Status: UPS Status screen.

Check Enable Shutdown Script if this remote UPS is the UPS providing power to the console server itself. If the UPS reaches critical battery status, the custom script in /etc/config/scripts/ups-shutdownruns, enabling you to perform any “last gasp” actions.

Click Apply.

8.2.3Controlling UPS powered computers

One of the advantages of having a Managed UPS is that you can configure computers that draw power through that UPS to shut down gracefully if you have UPS problems.

For Linux computers, set up upsmon on each computer and direct them to monitor the console server that is managing their UPS. This will set the specific conditions that will be used to initiate a power down of the computer. Non-critical servers may be powered down some seconds after the UPS starts running
