I tried that without success. Anyway this makes no sense because the test name is "roomtemp", "Temperature" is just the value.
My RRD-File seems to be ok. The problem seems to be in displaying the graph. Is there a way to debug this? There are no error messages in the logfiles.
Try replacing "roomtemp" in hobbitserver.cfg with "Temperature".I'm not sure if that makes a difference or not, though. Also, make sure the script doesn't generate any other text besides "Temperature: <value>"... I had a script that output some non-value text before the actual text, which was causing NCV to try to parse that into a number (and thus "NaN" - Not a Number).
Hi all,
I have just tried to set up a custom NCV graph tomonitor the room temperature. An external script generates a status page with the following output (example): Temperature: 22.92 I have added the following entries to my hobbitserver.cfg: TEST2RRD="....,roomtemp=ncv" NCV_roomtemp="Temperature:GAUGE" GRAPHS="...,roomtemp,ncv" My roomtemp.rrd File has been created and updates regularly. Output of rrdtool dump: <rrd> <version> 0001 </version> <step> 300 </step> <!-- Seconds --> <lastupdate> 1145970097 </lastupdate> <!-- 2006-04-25 15:01:37 METDST --> <ds> <name> Temperature </name> <type> GAUGE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> 0.0000000000e+00 </min> <max> NaN </max> <!-- PDP Status --> <last_ds> UNKN </last_ds> <value> 2.1708600000e+03 </value> <unknown_sec> 0 </unknown_sec> </ds> After that, I have added the following to my hobbitgraph.cfg: [roomtemp] TITLE Server Room Temperature YAXIS degrees DEF:temp=roomtemp.rrd:Temperature:AVERAGE LINE2:temp#FF0000:Room Temperature COMMENT:\n GPRINT:threads:LAST: \: %5.1lf (cur) GPRINT:threads:MAX: \: %5.1lf (max) GPRINT:threads:MIN: \: %5.1lf (min) GPRINT:threads:AVERAGE: \: %5.1lf (avg)\n There is no graph showing up on status page nor on the trends page. On the status page there is only a link "hobbit graph ncv:roomtemp" and on the trends page only a link "hobbit graph roomtemp". What am I doing wrong? Do I have to configure other things than these?
