[rrd-users] strange numbers
I'm getting some weird outputs on a counter graph I have, and I'm just trying to understand why. I'm actually using Cacti as a front-end, but I believe the problem is either with rrdtool, or confusion/misconfiguration on my part (which is likely). This is a quick log of the update commands, showing the actual counter value: 07/14/2003 11:42 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:532 07/14/2003 11:43 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:541 07/14/2003 11:44 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:550 07/14/2003 11:45 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:559 07/14/2003 11:46 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:569 07/14/2003 11:47 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:578 07/14/2003 11:48 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:586 07/14/2003 11:49 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:594 07/14/2003 11:50 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:604 07/14/2003 11:51 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:613 07/14/2003 11:52 AM - CMD: /var/mwt/rrdtool/bin/rrdtool update /var/mwt/htdocs/cacti/rra/in1cnt_9.rrd --template in1cnt N:620 rrdtool fetch AVERAGE output: 1058197320: 1.83e-01 1058197380: 1.505556e-01 1058197440: 1.50e-01 1058197500: 1.50e-01 1058197560: 1.663889e-01 1058197620: 1.502778e-01 1058197680: 1.336111e-01 1058197740: 1.33e-01 1058197800: 1.66e-01 1058197860: 1.4785974499e-01 MAX and MIN both have the same output (why is that?)

The other RRAs will differ. Your setup does however make it easy to use the same grapher script for all of min, avg and max.

Alex van den Bogaerdt wrote: difference in time: few seconds (60 or so, not very accurate due to N) difference in value: 9 value in the range of 0.18 per second. Like I said, this was probably my fault. I was thinking about it as per minute instead of per second. I'm used to dealing with rrdtool with 5 minute intervals, I guess I had a brainfart trying to think of it in terms of 1 minute. min(x) == avg(x) == max(x) It only matters if you have more than one sample: This makes sense, too. I just got confused when I got the same output, but it's exactly as you say, the reason that's there is to be able to use the same scripts no matter what interval or consolidation function. Probably a bad day for me to be programming... :p Thanks for the help ttyl, greg (btw, sorry about duplicate posts.. mozilla told me it couldn't send, and apparently sent it anyways..) -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdminhttp://www.ee.ethz.ch/~slist/lsg2.cgi
