The weird thing is that, this time, I'm not trying to see a rate, but how many and when this errors ocurr. I'm using cacti with a lot of other graphs. On this ORA- errors graph I can see peaks when something bad happens. Using zoom feature from I can get peak hour and minute and see how many erros happen. Any way, ABSOLUTE consolidation is new for me -- rrdtool as a whole is -- I though thay was only AVERAGE, MAX, MIN and LAST ones. I'll study ABSOLUTE with care, it may be what I want []'s _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
