hi, i read alex' really usefull docs from www.vandenbogaerdt.nl/rrdtool but still don't get the point about normalisation.
i thought i could prevent normalisation by updating at times that are multiples of stepsize. so if i `rrdtool create test.rrd --start 1146061700 --step 300 DS:test:GAUGE:600:U:U RRA:LAST:0.5:1:10` and start updating at 1146061700 and then update at 1146062000 and at 1146062300 and so on, i can dump the exact values i provided to the rrdupdate command, since they arent normalized. i used the exact time during updates (not N:), to be shure to fill the right slot. i thought i got it, but the next example made me nervous. i have an rrd with the following parameters: step = 300 ds[users].type = "GAUGE" ds[users].minimal_heartbeat = 600 ds[users].min = 0.0000000000e+00 ds[users].max = 5.0000000000e+02 ds[users].last_ds = "UNKN" ds[users].value = 4.8000000000e+02 ds[users].unknown_sec = 0 rra[0].cf = "AVERAGE" rra[0].rows = 600 rra[0].pdp_per_row = 1 rra[0].xff = 5.0000000000e-01 rra[0].cdp_prep[0].value = NaN rra[0].cdp_prep[0].unknown_datapoints = 0 i provided only integers to rrdupdate (4, 5 and 6 [logged in users]), but i see a 4.8 value. i have pretty much data in this rra that became normalized since the update-times didn't match the rra-slots. i changed the update-process, so updates where provided with exact times, but i still get values that are normalized (the 4.8) is that because of the pervious 'normalized data' that is allready in the rra, or am i wrong in thinking that i could get the exact values out of rrdtool, that i provided during update? any enlightenment appreciated thanx, thomas -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
