Hi, I am using rrdtool-1.2.15 for drawing the point values in trend graph, but tool is consuming a lot of RAM. Every time the rrdtool invoked the RAM size degraded which eventually hanged up our application.
Can anyone suggest me what are the limitations of rrdtool? And why this hang up occurs?

It was possible to mouse-over a data point, right click and a box would open showing information On that data point such as Time, data point value (level,percent, etc) I have searched but found nothing. Does anyone know if this still exists in some obscure Database, server, etc ??? If so, can I get either a copy of the script or can someone please point in the right direction?

Wiliam, to graph to the top(bottom) edge of the canvas you need a value of +(-)inf. ex. DEF:temp=some.rrd:temp:AVERAGE DEF:onoff=some.rrd:onoff:LAST CDEF:back=onoff,INF,* # if onoff != 0 this will be INF, otherwise 0 AREA:back#ff000020 # add 4th color value for transparency LINE1:temp#0000ff If you want red(off)/green(on), this will look like: DEF:temp=some.rrd:temp:AVERAGE DEF:onoff=some.rrd:onoff:LAST CDEF:red=onoff,0,EQ,INF,0,IF # if onoff == 0 this will be INF, otherwise 0 CDEF:green=onoff,INF,* # if onoff != 0 this will be INF, otherwise 0 AREA:red#ff000020 # add 4th color value for transparency AREA:green#00ff0020 # add 4th color value for transparency LINE1:temp#0000ff Of course you can make this depending of some value, eq: CDEF:red=temp,50,LT,0,INF,IF CDEF:green=temp,50,LT,INF,0,IF haven't tested it, but unless there's a typo it should work. hth - Karl _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
