I am new to RRD, but have spent about 12 hours struggling with this, so I hope someone can help.
I am creating an rrd /usr/bin/rrdtool create /tmp/ea.rrd --start 1240207200 --step 7200 DS:ds:GAUGE:43200:0:100 RRA:LAST:0.5:1:100 And loading some data into it (I realize the values are all one) /usr/bin/rrdtool update /tmp/ea.rrd 1240246749:1 1240252503:1 1240259704:1 1240266904:1 1240274104:1 1240281305:1 1240288503:1 1240295704:1 1240302903:1 1240310104:1 1240317304:1 1240324504:1 1240331703:1 1240338903:1 1240346103:1 1240353304:1 1240360503:1 1240367704:1 1240374903:1 1240382104:1 1240389304:1 1240396503:1 1240403704:1 1240410904:1 Now, I just want to print the data out. I try /usr/bin/rrdtool graph /tmp/ea.rrd --start 20090420 'DEF:ds0=/tmp/ea.rrd:ds:LAST' 'PRINT:ds0:LAST:%2.2lf' And get 0x0 100.00 I was expecting to get a list of values? On a related note, these values represent time points where a device is on-line (hence one; if it was off line, the value would be zero). I would like to compute availability by computing every 24 hours the number of points that are 1 over the total number (which should be 12). Any suggestions on how to do that?
