Hi, I'm trying to do a graph that's red for too hot, green for OK, and blue for too cold. The script below sort of works but only if I overlay the red and blue over the green. I guess that's because of the CDEF:righttemp line doing the wrong thing. I only want it to show if the temperature is between $hi and $lo. It shows all the time. Why?
#!/bin/bash cd /root/rrdtool starttime=`date -d "119 minutes ago" +%s` endtime=`date -d "1 minutes" +%s` hi=30 lo=27 /usr/bin/rrdtool graph /var/www/temperature.png \ -w 600 -h 200 -v Temperature \ --start $starttime --end $endtime \ DEF:mytemp=temperature.rrd:temp:AVERAGE \ CDEF:toohot=mytemp,$hi,GE,mytemp,UNKN,IF \ CDEF:righttemp=mytemp,$lo,GT,$hi,LT,mytemp,UNKN,IF \ CDEF:toocold=mytemp,$lo,LE,mytemp,UNKN,IF \ HRULE:100#FF0000:"Boiling" \ HRULE:0#0000FF:"Freezing" \ LINE:righttemp#00AA00:"Temperature OK" \ LINE:toohot#AA0000:"Too Hot" \ LINE:toocold#0000AA:"Too Cold" Thanks, -- Mark Ter Morshuizen _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
