Hi .. I have a scripte updating my rrd. In this case wlo.rrd. My
script returns three values, however rrdtool is mailing an error to me that
I am submitting 4 elements. On the the elements I'm storing have a decimal
place. e.g. 1.44 , which is the load average of one of my systems. Firstly,
here is the cron e-mail, less the env info--

/etc/cron.minute/update.wlo:
ERROR: expected 3 data source readings (got 4) from N:1:1.48:::...
My script which runs once every 60 seconds --
[EMAIL PROTECTED] cron.minute]# cat update.wlo
master=`rsh wlo /bin/totinf` #returns 3 lines of data
#echo "$master"
ld=`echo "$master"|gawk '{ if (NR == 1) print $0 }'`
#echo "$ld"
users=`echo "$master"|gawk '{ if (NR == 2) print $0 }'`
#echo "$users"
tout=`echo "$master"|gawk '{ if (NR == 3) print $0 }'`
#echo "$tout"
rrdtool update /usr/local/rrdwork/wlo.rrd N:$ld:$users:$tout
#echo $ld $users $tout
---------------------------------------+
My rules for my rrd are as follows:
rrdtool create --step 60 wlo.rrd \
DS:load:GAUGE:600:0:100 \
DS:users:GAUGE:120:0:120 \
DS:tout:GAUGE:120:0:200 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797
My rrd isn't optimized very well. I need to gather enough samples for 1
year, 6 month, 1 month,1 week and 1 hour without becoming too large. I had
problems following the examples for the archives consolidation functions and
where the x-files factor could be derived. I will be storing 40 databases
and need to not exceed 100 megs for a year of data.
I look forward to your responses and thank you for your help in
advance.. =)
Sincerely,
Eric Collins
