CANNOT FIND DATA SOURCE: Assistance plz? :)

Krism · Guest

Greetings - I have Cacti up and running without a hitch - that is untill I attempt to Save a Data Source or similar. The problem lies in the following error:

CANNOT FIND DATA SOURCE: /var/www/cacti/rra/core0.rrd

which is followed by t he rrdtool output at the top of the config screen under my entry for core0.

Cacti seems to refuse to write to the rra/ or log/ directory as the log file hasnt budged a byte. I have my ownership and permissions aligned for the Cactiuser read/write/execute... What else am I missing here?

Thanks!

I ran:
/usr/local/bin/rrdtool create /var/www/cacti/rra/core0.rrd --step 300 DS:core0:GAUGE:600:0:1 RRA:AVERAGE:0.5:6:700 RRA:MAX:0.5:6:700

from the command line and was able to produce the desired core0.rrd with no problem. Placement of that file within the rra/ firectory eliminated the error but not the over all problem. Still unable to put my finger on why Cacti is unable to generate these files??

Thanks!

....I'm sure it's something simple. Could you help us newbies?

Thanks.

I'm on Linux, so it's not the space in the Apache path problem....

I fixed my issue....found that the crontab wasn't edited right for the cactiuser. I ran the cmd.php as cactiuser and the rrd files were created just fine.
