[rrd-users] Second opinion ...

Hello all,

     I am trying to understand a few things regarding RRD. I was
started on a project with RRD to average the users across our server
cluster to check (I guess) that we have balanced the load across the
system. I am running a RRD that is to update the DS's once a day with
the returned values of the user polling script.

    Where I am lost is that I created a RRD that has a step of 36400
(1 day) and 12 DS's that are set at DS:one:GAUGE:36400:0:1000. The RRA
is set as AVERAGE:0.5:1:365. If this is correct for setting up the RRD
for once a day updates and is this normal? If it is then my problems
are, I guess in the update itself.

   When I run my script to update the DS's I get ds[one] . last_ds =
"UNKN" , yet I know there is data being polled, just not injected into
the RRD. The update is as follows:


one=$(grep one $fileloc | awk -F': ' '{print $2}'):\
two=$(grep two $fileloc | awk -F': ' '{print $2}'):\
three=$(grep three $fileloc | awk -F': ' '{print $2}'):\
four=$(grep four $fileloc | awk -F': ' '{print $2}'):\
five=$(grep five$fileloc | awk -F': ' '{print $2}'):\
six=$(grep six $fileloc | awk -F': ' '{print $2}'):\
seven=$(grep seven $fileloc | awk -F': ' '{print $2}'):\
eight=$(grep eight $fileloc | awk -F': ' '{print $2}'):\
nine=$(grep nine $fileloc | awk -F': ' '{print $2}'):\
ten=$(grep ten $fileloc | awk -F': ' '{print $2}'):\
eleven=$(grep eleven $fileloc | awk -F': ' '{print $2}'):\
twelve=$(grep twelve $fileloc | awk -F': ' '{print $2}'):

rrdtool update data2.rrd

Will this even work .... I am not very educated in how RRD works yet
but I am trying to learn and any help would be appreciated.
