check_em1.pl -H host -u sensor_unit -q t|h|w [ -p port ] [ -P web_path ] [ -w warn ] [ -c crit ]
-H The ip or hostname of the SnesorTronics EM1 box. -p The port of the webservice running on the EM1, default is 80. -P The webpath for the servicedata, normally '/data'. -u The sensorunit (1-4) -q Which sensor to query (t=temperature, h=humidity, w=wetness) -w The warning threshold. -c The critical threshold. -h Display's this screen here... -U Display's a little usage.
- start <= end
The startvalue have to be less than the endvalue
- start and ':' is not required if start is infinity>
If you set a threshold of '12' it's the same like ':12'
if range is of format "start:" and end is not specified, assume end is infinity
alert is raised if metric is outside start and end range (inclusive of endpoints)
if range starts is lower than end then alert is inside this range (inclusive of endpoints)
