[root@capra_nag tmp]# ./check_em01
Copyright (c) 2005-2009 Esensors, Inc <TechHelp@eEsensors.com>
This plugin is written mainly for Nagios/Cacti/RRDTool, but can work standalone too.
It returns the HVAC data from the EM01 Websensor

usage:
 ./check_em01 [hostname] [T/H/I] [LowWarning HighWarning LowCritical HighCritical]

Only the hostname is mandatory. The rest of the arguments are optional
T is for Temperature data, H for Humidity Data and I for Illumination data
Examples:
This will return all HVAC data:
 ./check_em01 192.168.0.2

This will return only Illumination data:
 ./check_em01 192.168.0.2 I

This will return temperature data with status:
 ./check_em01 192.168.0.2 T 65 85 60 90

This will return humidity data with status:
 ./check_em01 192.168.0.2 H 25.5 50 15 70.5

This will return Cacti/RRDTool format:
 ./check_em01 192.168.0.2 G
