Hello List, I searched the web for my problem but could find something that helped. So here is my problem:
I've created several Graphs and databases. But all Databases that have COUNTER Datasources react strange sometimes. The script below emulates the data polling process and writes every 60 Seconds values into the database. I multiply them with 60 because I want to display the Mails processed per minute. So the value steps are based on 60. But I expected some different values: i.e. 1180027440: 0.0000000000e+00 5.5041617224e-01 1.1008323445e+00 0.0000000000e+00 0.0000000000e+00 should be 1180027440: 0.0000000000e+00 1.0000000000e+00 2.0000000000e+00 0.0000000000e+00 0.0000000000e+00 and so on. Can someone tell me what I'm doing wrong? Below you find the polling emulation script and the output of rrdfetch. $ cat test.sh rrdtool create ../db/mail.rrd --step 60 DS:total:COUNTER:120:0:U DS:spam:COUNTER:120:0:U DS:relay:COUNTER:120:0:U DS:error:COUNTER:120:0:U DS:queue:GAUGE:120:0:U RRA:AVERAGE:0.5:1:2160 sleep 60 rrdtool update ../db/mail.rrd N:16920:420:420:0:0 sleep 60 rrdtool update ../db/mail.rrd N:16920:420:420:0:0 sleep 60 rrdtool update ../db/mail.rrd N:16920:480:540:0:0 sleep 60 rrdtool update ../db/mail.rrd N:16980:480:540:0:0 sleep 60 rrdtool fetch ../db/mail.rrd AVERAGE | tail -n 15 $bash test.sh 1180026780: nan nan nan nan nan 1180026840: nan nan nan nan nan 1180026900: nan nan nan nan nan 1180026960: nan nan nan nan nan 1180027020: nan nan nan nan nan 1180027080: nan nan nan nan nan 1180027140: nan nan nan nan nan 1180027200: nan nan nan nan nan 1180027260: nan nan nan nan nan 1180027320: nan nan nan nan 0.0000000000e+00 1180027380: 0.0000000000e+00 0.0000000000e+00 0.0000000000e+00 0.0000000000e+00 0.0000000000e+00 1180027440: 0.0000000000e+00 5.5041617224e-01 1.1008323445e+00 0.0000000000e+00 0.0000000000e+00 1180027500: 5.5024873405e-01 4.4958382776e-01 8.9916765553e-01 0.0000000000e+00 0.0000000000e+00 1180027560: nan nan nan nan nan 1180027620: nan nan nan nan nan $ _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
