# # these harddiscs will be monitored using hddtemp:
# env.discs /dev/sda /dev/sdb
#
# # Configure verious values for the "Core 0" value on the
# # coretemp-isa-0000 chip:
# env.coretemp_isa_0000_core_0_label CPU0/Core0
# env.coretemp_isa_0000_core_0_info Interesting sensor
# env.coretemp_isa_0000_core_0_warning 30:50
# env.coretemp_isa_0000_core_0_critical 25:55
# env.coretemp_isa_0000_core_0_critical 25:55
#
# # Ignore a chip and an individual value:
# env.ignore adt7470_i2c_0_2e i5k_amb_isa_0000_ch__1_dimm_9
#
# Changelog:
#
# 2012-07-01
# * Add ability to override label via env variable
# * No longer limit length of field names
