[rrd-users] Re: mail scripts

[Wendy Faulkner]

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?  Thanks.
