rrd files only get updated when i run poller.php manually

Hi friends,

The graphs stay blank unless I run poller.php manually. Then all of the days get populated.

For example, i leave for the weekend, and I come back. All I would see for those 2 days would be blank graphs. After running poller.php, all the period in those two days get populated.

The permission for the directory are set to the user and not root. Cron log shows both poller.php and cmd.php being run at 5-min intervals:

Mar 12 17:45:00 cacti /usr/sbin/cron[3504]: (cacti) CMD (php /usr/local/share/cacti/poller.php > /dev/null 2>&1)
Mar 12 17:45:00 cacti /usr/sbin/cron[3505]: (root) CMD (/usr/libexec/atrun)
Mar 12 17:45:00 cacti /usr/sbin/cron[3506]: (cacti) CMD (/usr/local/bin/php /usr/local/share/cacti/cmd.php > /dev/null 2>&1)
Mar 12 17:50:00 cacti /usr/sbin/cron[3590]: (cacti) CMD (php /usr/local/share/cacti/poller.php > /dev/null 2>&1)
Mar 12 17:50:00 cacti /usr/sbin/cron[3591]: (root) CMD (/usr/libexec/atrun)
Mar 12 17:50:00 cacti /usr/sbin/cron[3592]: (cacti) CMD (/usr/local/bin/php /usr/local/share/cacti/cmd.php > /dev/null 2>&1)

What am i doing wrong?

/etc/passwd:
cacti:*:107:107:Cacti Sandbox:/nonexistent:/sbin/nologin

/etc/crontab:
*/5 * * * * cacti php /usr/local/share/cacti/poller.php > /dev/null 2>&1

crontab for cacti:
cacti# crontab -l -u cacti
*/5 * * * * /usr/local/bin/php /usr/local/share/cacti/cmd.php > /dev/null 2>&1

Permissions:
drwxr-xr-x 2 cacti cacti 512 Mar 12 14:45 log
drwxr-xr-x 2 cacti cacti 2048 Mar 12 16:37 rra

It's a new install on FreeBSD 6.2-STABLE

Thanks for any insight into this.

Only error i'm seeing is from httpd-errors:

cacti# tail /var/log/httpd-error.log
[Tue Mar 13 08:53:29 2007] [error] PHP Notice: Undefined index: cacti_version in /usr/local/share/cacti/include/auth.php on line 30
[Tue Mar 13 08:53:30 2007] [error] PHP Notice: Undefined index: cacti_version in /usr/local/share/cacti/include/auth.php on line 30
[Tue Mar 13 08:53:30 2007] [error] PHP Notice: Undefined index: cacti_version in /usr/local/share/cacti/include/auth.php on line 30

i am not getting any errors when I am running poller.php and cmd.php. Cacti.log looks clean. Where else should I look?

I, have debian Etch, apache2, php5, cacti the last version.

When run php poller.php make fine the graphics, the permission are this.

chown -R cactiuser:cacti rra log

Apache sendme this errors

ERROR: opening/var/www/apache2-default/graficas/rra/localhost_hdd_free_8.rrd': No such file or directory
ERROR: var/www/apache2-default/graficas/rra/localhost_load_1min_5.rrd': No such file or directory
ERROR: openngvar/www/apache2-default/graficas/rra/localhost_users_6.rrd': No such file or directory

My cron is this

cronttab -e

*/5 * * * * cactiuser php /var/www/apache2-default/graficas/poller.php > /tmp/cactilogs 2>&1

Make the folder cactilogs in tmp and put chown -R nobody.nogroup cactilogs.

Any ideas why not work??

Thanx

reconfigure cacti include/config.php, you must run the poller thats in the used tree, not some system wide copy or so.

Hi, in this file i have not modify nothing, just the database user etc, in Cacti setting, poller, see poller.php and cmd.php, by default is cmd.php, when change to poller.php, and execute php poller.php manually, appear error.

Ideas?

Man, I am sure it's something quite simple. I mean everything is working. It's gathering the appropriate data and storing them. It's just that the rrd files aren't being updated. What?!!?

Some please help.

jiml5000 · Post by **jiml5000** » Mon Mar 19, 2007 2:17 pm

Actually, my mistake artman67. When I made the changes suggested, I couldn't get any updated graphs even if i ran the poller manually.

What does that mean? Thanks.

Hi,
I have the same problem, everything seem to be in order but the graph is not updateing. I've tried useing poller.php and cactid. In both cases the graph stays blank. I'm useing Freebsd 6.2 on AMD64, php5-5.2.1_3, mysql-server-5.0.37, apache-2.2.4_2.
If anyone have an idea, I will be very gratefull.

Thanks in advance.
