n00b: poller.php under Debian

[swmspam]

I setup a Cacti box with a fresh install of Debian, apache2, mysql, php5, and installed cacti. The web interface came up right away, and setup a bunch of devices with SNMP data sources. No graphs. I'm logged into the cacti machine as root.

Code: Select all

# php /usr/share/cacti/site/poller.php

Runs without errors. I look into /var/lib/cacti/rra and there are no files. This may be a permission issue? I clear the permissions with a sledgehammer:

Code: Select all

# chmod -R 777 /var/lib/cacti/

Run poller.php again, but /rra/ directory remains empty.

After a couple hours, I noticed some files in the /rra/ directory. Screenshots attached of the Cacti web interface and the console.

If you have run poller.php as root (or some user <> "cactiuser"), the rra files may have wrong permissions.

I cleared all files:

Code: Select all

cd /var/lib/cacti/rra
rm *

Waited for the rra files to reappear. Cacti web interface has no change from my previously posted screenshot.

Additionally, I looked at the users:

Code: Select all

# cat /etc/passwd | cut -d":" -f1
root
daemon
bin
sys
sync
games
man
lp
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
nobody
libuuid
Debian-exim
statd
******
sshd
clamav
snmp
mysql

And now the cron.d file:

Code: Select all

MAILTO=root
*/5 * * * * www-data php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

Debian systems unfortunately have their own user layout (which I do not know). So please follow 2nd link of my sig to learn more
