Hi all, so while I've needed the one-shot value from my RRD I took this way:
Parameters: A single value, beetween 0.000 and 10.000 every 60 seconds. Here, how I have created my RRD db: rrdtool create conf/tal.rrd --start 1138199559 --step 60 DS:time:GAUGE:120:0:10 RRA:MAX:0.000:1:2880 And this is ok...for me (any suggestions/opinions is encouraged). To print simplest graph of daily values: $RRD graph --start -1d $WORKDIR/web/tal-daily.png DEF:time=$WORKDIR/conf/tal.rrd:time:MAX LINE1:time#FF0000 VDEF:timeMAX=time,MAXIMUM VDEF:timeMIN=time,MINIMUM VDEF:timeAVG=time,AVERAGE COMMENT:"Maximum response time\: " GPRINT:timeMAX:"%7.3lf %Sseconds\n" COMMENT:"Average response time\: " GPRINT:timeAVG:"%7.3lf %Sseconds\n" COMMENT:"Minimum response time\: " GPRINT:timeMIN:"%7.3lf %Sseconds\n" And this is already OK. Now, i've tried function CDEF:smoothed=time,1800,TREND and this is very good... but for example: I need to keep in foreground every value with 0.000. This is a bad value (for me means that my monitored applications is not reachable). It's possibile to count how many 0.000 value I have in the last day? And also... print a single, separated, vertical line for everyone of this value? or another reference on my graphs? I've tried with: CDEF:unknown=time,UNKN but i receive error: ERROR: RPN final stack size != 1 Mmm..somebody can help me?
