====== Zabbix: Monitor an APC UPS with apcupsd (no SNMP required)  ======

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.

In the Zabbix web interface
  - Install the zbx_apcupsd_template.xml (it has 5 items and 2 triggers for generating Power Down and Low Battery alerts) ([[http://pastebin.com/raw.php?i=aCF1Jkht|zbx_apcupsd_template.xml]])
  - Add the "apcupsd Template" to the monitoring host
