Well this is what Observium displays when graphing the sensor:
But if I use the same RRD and graph it myself, I get:

Noticing the ‘value’ figure is correct on the optic’s power status page, we subsequently found all data in the RRD to be correct. eg: <!-- 2016-02-25 20:50:00 GMT / 1456433400 --> <row><v>6.1840000000e-04</v></row> <!-- 2016-02-25 20:55:00 GMT / 1456433700 --> <row><v>6.1300000000e-04</v></row> <!-- 2016-02-25 21:00:00 GMT / 1456434000 --> <row><v>6.1435000000e-04</v></row> It just seems the rrdtool graph function is not rendering this sensor data with anything useful. The graph is being generated with something like this: rrdtool graph /tmp/FLjPO7rtfRJQOfGn.png -Y --lower-limit 0 --alt-autoscale-max --start 1456347228 --end 1456433628 --width 1152 --height 300 -c BACK#EEEEEE00 -c SHADEA#EEEEEE00 -c SHADEB#EEEEEE00 -c FONT#000000 -c CANVAS#FFFFFF00 -c GRID#a5a5a5 -c MGRID#FF9999 -c FRAME#5e5e5e -c ARROW#5e5e5e -R normal --font LEGEND:8:'DroidSansMono,DejaVuSansMono' --font AXIS:7:'DroidSansMono,DejaVuSansMono' --font-render-mode normal -E -A COMMENT:' Last Max\n' DEF:sensor=/srv/www/iss/observium/rrd/t40-ar14/sensor-power-cisco-entity-sensor-58513400.rrd:sensor:AVERAGE DEF:sensor_max=/srv/www/iss/observium/rrd/t40-ar14/sensor-power-cisco-entity-sensor-58513400.rrd:sensor:MAX DEF:sensor_min=/srv/www/iss/observium/rrd/t40-ar14/sensor-power-cisco-entity-sensor-58513400.rrd:sensor:MIN AREA:sensor_max#c5c5c5 AREA:sensor_min#ffffffff LINE1.5:sensor#cc0000:'Transceiver Rx Power -' GPRINT:sensor:LAST:%6.2lfW GPRINT:sensor:MAX:%6.2lfW\\l HRULE:0.0009585#999999::dashes Seeing the data collected is in the order of 10^-4 d.p. small, how can we stop this being rounded to 0 all the time on a the graph? I understand completely this is rrdtool not automatically choosing a very good scale for you, but is there any way to detect these low values and fix them up for the graphs by order of 1000 say?
