[rrd-users] simple graphing

[Dave Stern - Former Rocket Scientist]

I'm exceedingly new to RRDtool and am trying to find the simplest way to
graph data from an existing file of the format
MMM DD HH:MIN  datapoint
   eg
Jan  1 12:00   123
Jan  1 12:15    80
Jan  1 12:30   257

I initialized the database using

rrdtool create test.rrd --start N DS:in:GAUGE:900:U:U RRA:AVERAGE:0.5:1:432

To insert the data,  I would like to ideally do something like
    rrdtool update test.rrd `cat /tmp/data.2`
but that cleayly wont work even if I massage the data to look like
1200:123
1215:80
1230:257

For that matter,making a script that says
rrdtool update test.rrd U:123
rrdtool update test.rrd U:80
rrdtool update test.rrd U:257
 wont do it

Clearly the problem is my time format. Is there some way to tell rrdtool to
just take the timestamp as is without calculating seconds from an epoch?

Thanks
