CANNOT FIND DATA SOURCE

Hello,

for some reason I am getting this error and the rra is empty.
The permissions are fine and the cacti user is the owner.

however when I try to run the command manually i.e:
/usr/local/bin/rrdtool create <cacti installation>/rra/ping_uunet_phi.rrd

ERROR: you must define at least one Round Robin Archive

when I tried to run the cron job manually I received
# php<cacti installation>/cmd.php > /dev/null 2 > & 1
Ambiguous output redirect.

any ideas

thanks in advance

I think I see some spaces in your output redirect....try /dev/null 2>&1 (no spaces except before the 2)

Also, it can take a full poll interval (time between running cmd.php as defined in your crontab) before the RRD data sources will be created.....that is unless you run the cmd.php manually in which case it should be created right away.

The rrdtool create actually gives a lot of flags (as separated by the \):
(an example from my config):

/usr/local/rrdtool/bin/rrdtool create \
/var/www/html/cacti/rra/welles_int_e151_in.rrd \
--step 300 \
DS:welles_int_e151_in:COUNTER:600:0:10000000000 \
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 \

So you have a Data Source (DS: flag) and several RRA's (RRA: flag)

From the # prompt, looks like you're running as root. Is this OK?

Next, make sure "which php" shows the path to php...for me 's /usr/local/bin/php

then make sure you have a space between php and the path to cmd.php...e.g.

prompt>php /var/www/html/cacti/cmd.php > /dev/null 2>&1

(note the spaces after the first php, then before the first > and one after it before /dev/null)

does this help?

php can be found at /usr/local/bin/php
and php -v provides the corrct status

I tried to run the cmd both in root and cacti user.
also all the spaces are in the correct place.

again thanks for your efforts
