how to get the current temp in a warning message sent

[Zembower, Kevin]

Randy, the only way I was able to do this was to write the return
temperature value in the message that the plug-in sent. Below, find my
plug-in code, if this would help.

    Test ambient temperaure in Farenheit plugin for Nagios
    Copyright (c) 2007 Kevin Zembower

    This plugin is used to check the ambient temperature in degrees
    Farenheit on Dell PowerEdge servers using SNMP.

    Requirements:
    This plugin requires /usr/lib/nagios/plugins/check_snmp.

    usage: $0 [-h] [-d] [-H hostaddress] [-w warn] [-c crit]

    -h          print this short help message
    hostaddress address of host to check
    warn        Warning threshold value in degrees Farenheit
    crit        Critical threshold value in degrees Farenheit
    -d          Turn on debugging output
