In OPNsense bietet Apcupsd wichtige UPS (Uninterruptible Power Supply)-Verwaltungsmerkmale, insbesondere für APC-UPS-Geräte. Diese Integration sichert, dass das System bei Stromausfällen effizient mit Strom umgehen kann und sichere Herunterfahrensverfahren zur Datenintegrität und Verhinderung von Hardwarebeschädigungen auslöst. Durch das ständige Überwachen des UPS-Zustands erhöht Apcupsd die Zuverlässigkeit und Resilienz des Netzwerkinfrastruktures, was OPNsense zu einer robusteren Lösung für Umgebungen macht, in denen Stromstabilität entscheidend ist.

• Installiere Apcupsd plugin in Opnsense
• Verbinde UPS hardware mit Opnsense hardware mit einem usb Kabel. Das plugin erkennt die Verbindung automatisch.
• Konfiguriere die Settings in der Oberfläche:

• Erstelle den code im in der Datei: /usr/local/etc/apcupsd/offbattery

#!/bin/sh

# Find the shessl script under /etc/apcupsd
# /etc/apcupsd/apccontrol calls the script if
# the UPS falls back to main after energy failure.
# An e-mail message will be sent to root.

echo "$(date) - offbattery script started" >> /var/log/apcupsd_eventscripts.log

HOSTNAME="APC Back-UPS"
MSG="$HOSTNAME UPS $1 Power has returned"

(
  echo "Subject: $MSG"
  echo " "
  echo "$MSG"
  echo " "
  /usr/local/sbin/apcaccess status
) | $APCUPSD_MAIL -s "$MSG" $SYSADMIN

# Wake up the hardware, which is necessary.
wake igb0 macaddress
if [ $? -eq 0 ]; then
  echo "Magic packet sent successfully" >> /var/log/apcupsd_eventscripts.log
else
  echo "Failed to send magic packet" >> /var/log/apcupsd_eventscripts.log
fi

# Wait for a minute to allow the server to wake up
sleep 60

• Define the code in the path /usr/local/etc/apcupsd/onbattery

#!/bin/sh

# This shell script if placed in /etc/apcupsd
# will be called by /etc/apcupsd/apccontrol when the UPS
# goes on batteries.
# We send an email message to root to notify him.
# This script send a command to run a shutDown script on a server to make a secure shutdown.

echo "$(date) - onbattery script started" >> /var/log/apcupsd_eventscripts.log

Look at the status, if all configurations are correct it looks like:

The Dashboard automatically added a widget for apcupsd. I looks like:
