===== Description =====
This script monitors Temperature, Battery Charge %, and Input/Output Voltage (to determine whether commercial power is being used).  It utilizes SNMP OIDs are based on APC 6000RT UPS.
===== Installation =====
=== Client side ===
Enable SNMPv1 on the APC UPS and allow the xymon server access.
=== Server side ===
  - Ordered List ItemMake a copy for each UPS in your environment.
  - Ordered List ItemEdit the script and update the $UPS variable with the FQN for the UPS
  - Ordered List ItemAdd the following example to the /usr/share/xymon-client/etc/clientlaunch.cfg:

Add the following to /etc/xymon/xymonserver.cfg:

    TEST2RRD:TempC=ncv,volt=ncv,batt=ncv
    ...
    GRAPHS:TempC,volt,batt
    ...
    NCV_TempC="Reading:GAUGE"
    NCV_batt="BatteryTime:GAUGE"
    NCV_volt="InputVoltage:GAUGE,OutputVoltage:GAUGE"
