====== Configure CyberPower UPS Monitoring on Linux ======

===== PowerPanel Business 4 Linux =====

**Download**: https://www.cyberpowersystems.com/product/software/power-panel-business/powerpanel-business-4-7-0-linux/

**Manual**: https://dl4jz3rbrsfum.cloudfront.net/documents/CyberPower-UM-PPB-447.pdf

==== Installation ====

:!: Tested with XCP-ng 8.2 and a CyberPower CPS1500AVR UPS.

:!: Connect the included USB or serial cable to UPS.

:!: We use the **Local** version for single servers with USB or serial cable connected UPSs.

<file>
wget https://dl4jz3rbrsfum.cloudfront.net/software/ppb490-linux-x86_x64.sh
chmod +x ppb470-linux-x86_x64.sh
./ppb470-linux-x86_x64.sh
</file>

Check that services started:

<file>
systemctl status ppbed.service
systemctl status ppbwd.service
</file>

==== Access ====

Default credentials:

^Username ^Password  ^
|admin    |admin     |

Use a web browser from a workstation:

**http://ip.of.linux.svr:3052**

==== Configuration ====

We don't want the server to shut down immediately upon power failure...we want to wait until the battery gets low before we actually run the shutdown command.

Edit the PowerPanel configuration file:

<file>
vi /etc/pwrstatd.conf
</file>

And change:

<file>
powerfail-shutdown = no    #we want to shut down the UPS when the battery gets low, not when the power fails
shutdown-sustain = 200     #set this to a little longer than it takes to shut your server down
lowbatt-threshold = 15     #don't run the battery completely dead
</file>

Restart the service:

<file>
/etc/init.d/pwrstatd restart
</file>

or

<file>
service pwrstatd restart
</file>

Commands that run upon power-fail and low-battery events are also specified in the /etc/pwrstatd.conf configuration file. By default, it specifies:

<file>
/etc/pwrstatd-powerfail.sh
</file>

and

<file>
/etc/pwrstatd-lowbatt.sh
</file>

===== Testing =====

You may want to change the lowbatt-threshold to ''90'' so the box shuts down in the shortest time, then change it back when finished testing.

<file>
lowbatt-threshold = 90

service pwrstatd restart

tail -f /var/log/pwrstatd.log
</file>

===== XenServer =====

:!: These settings are probably not ideal, but are a good start.  I think the goal would be to confirm that all VMs are shut nown properly before issuing the shutdown command.

Modifications to above for XenServer:

<file>
vi /etc/pwrstatd.conf
</file>

And change:

<file>
powerfail-shutdown = no    #we want to shut down the UPS when the battery gets low, not when the power fails
shutdown-sustain = 600     #set this to a little longer than it takes to shut down all VMs and your server
lowbatt-threshold = 35     #don't run the battery completely dead and give time to shut down
lowbatt-duration = 60      #allow the script to run for 60 seconds before the shutdown
</file>

<file>
vi /etc/pwrstatd-lowbatt.sh
</file>

and append:

<file>
xe vm-shutdown power-state=running --multiple
</file>
