check temperature through a T3511 device

+ Check Temperature toc ++ Introduction This module will check the temperature reading from a T3511 device from Comet. ++ The device The T3511 device from Comet read the temperature and relative humidity in the air surrounding the measuring probe. ++ The module The module itself will download a web page from the temperature device using _wget_. The web page is parsed for the temperature reading, which is then compared to the threasholds sent to the module. More information on this environmental monitoring device can be found here: http://www.cometsystem.cz/english/humidity-transmitter-ethernet.htm +++ Usage $ ./check_temperature.sh Usage: check_temperature.sh -h, --help check_temperature.sh -V, --version check_temperature.sh DEVICE_ADDRESS WARNING_TRESHOLD CRITICAL_TRESHOLD Example: mluebeck@dmz0vp-nag1:/usr/local/nagios/libexec30$ ./check_temperature.sh temp01 25 30 Temperature OK - TEMP: 21 mluebeck@dmz0vp-nag1:/usr/local/nagios/libexec31$ ./check_temperature.sh temp01 20 25 WARNING - TEMP TOO HIGH - TEMP: 21 mluebeck@dmz0vp-nag1:/usr/local/nagios/libexec32 $ ./check_temperature.sh temp01 15 20 CRITICAL - TEMP TOO HIGH - TEMP: 21 $ ./check_temperature.sh wrong_device_address 15 20 CRITICAL - NO RESPONSE FROM THE DEVICE +++ Installation Place the check_temperature.sh script in your libexec directory.
