Monitoring an APC UPS without snmp is not so difficult. If you are already using the apcupsd daemon, feeding this data to Zabbix as UserParameter is all about putting the data into a file that Zabbix can read.
This is my configuration of apcupsd for a SmartUPS 5000 connected to the Local Network (1.2.3.4 is the IP address of my UPS – change your /etc/apcupsd/apcupsd.conf file to match your network setup).
## apcupsd.conf v1.1 ## UPSNAME SmartUPS5000 UPSCABLE ether UPSTYPE pcnet 1.2.3.4:apc DEVICE LOCKFILE /var/lock UPSCLASS standalone UPSMODE disable POLLTIME 60 ONBATTERYDELAY 15 # BATTERYLEVEL, MINUTES, and TIMEOUT work in conjunction, so # the first that occurs will cause the initation of a shutdown. BATTERYLEVEL 10 MINUTES 5 TIMEOUT 0 #set it to 0 for SmartUPS devices STATTIME 50 STATFILE /var/log/apcupsd.status LOGSTATS off DATATIME 0
As you can see in the config file, the UPS status is dumped every 50 seconds within the /var/log/apcupsd.status file.
The status of the UPS can be seen with the apcaccess command

We are interested in line/battery voltages, UPS load and battery charge.
With awk we can easily get these values and provide them to Zabbix Server as User Parameter.
On the host that runs zabbix_agentd, edit the /etc/zabbix/zabbix_agentd.conf and insert the following lines:
UserParameter=apcupsd.linev,awk < /var/log/apcupsd.status '/^(LINEV).*:/ { print $3 }'
UserParameter=apcupsd.loadpct,awk < /var/log/apcupsd.status '/^(LOADPCT).*:/ { print $3 }'
UserParameter=apcupsd.battcharge,awk < /var/log/apcupsd.status '/^(BCHARGE).*:/ { print $3 }'
UserParameter=apcupsd.timeleft,awk < /var/log/apcupsd.status '/^(TIMELEFT).*:/ { print $3 }'
UserParameter=apcupsd.battv,awk < /var/log/apcupsd.status '/^(BATTV).*:/ { print $3 }'
and restart the zabbix_agent.
