Ok. Thanks for your help. I started with: rrdtool create virus.rrd --start 988174600 --step 3600 DS:input:GAUGE:172000:U:U RRA:MAX:0.5:1:600 RRA:MAX:0.5:6:700 RRA:MAX:0.5:24:775 RRA:MAX:0.5:288:797
and then ran a script which inputted a lot of data: rrdtool update virus.rrd 988174800:3 rrdtool update virus.rrd 988261200:13 rrdtool update virus.rrd 988347600:19 rrdtool update virus.rrd 988434000:3 ... rrdtool update virus.rrd 992322000:25 rrdtool update virus.rrd 992408400:16 rrdtool update virus.rrd 992494800:38 rrdtool fetch virus.rrd MAX just shows NaN for everything. A graph shows no data /usr/local/rrdtool-1.0.33/bin/rrdtool graph virus.gif --start 992494800 --vertial-label "viruses" DEF:myspeed=virus.rrd:input:MAX CDEF:realspeed=myspeed LINE2realspeed#FF0000 Any ideas?
