I have Version 0.8.7b installed on Solaris 10. I can run poller.php from the cacti user and see the graphs generate, but poller.php will not run from cron. When I look in /var/cron/log, I do not see the cron run. I tried sending output to a file but it does not populate. Below is the cron and when run from the cacti user.
bash-3.00$ crontab -l
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/bin/php /var/apache2/htdocs/cacti/poller.php > /dev/null 2>&1
bash-3.00$ /usr/local/bin/php /var/apache2/htdocs/cacti/poller.php

TheWitness, thank you for the reply. I am not sure how to correct the "PHP Warning: Module 'zlib' already loaded in Unknown on line 0"
php -v displays:
bash-3.00$ /usr/local/bin/php -v

I reviewed System Utilities -> Technical Support and everything seems normal.
Do you know how I can determine why the cacti cron does not appear to run? I don't see anything for it in /var/cron/log , but see jobs for other users working. If a job fails does it still show up in the log?
Thanks.
lipos, thanks for hijacking the thread! What you posted has nothing to do with the issue I am having.
Can anyone help? I can run poller.php from the user account, get a zlib error but the graphs generate. When set the cron in my previous post, it does not appear to run since I do not see it in /var/cron/log. I verified the cron is set with correct permissions. When I send the output to a file nothing is added to the file.
Does anyone know common ways to troubleshoot if cron does not run? I set it the same way as other users are set and their jobs are running and showing in /var/cron/log.
I was able to run poller.php for my user account, I was even forcing cron as well plus others cron job was working fine.. but if you don't need my help I'm out!
The only thing I will add is - chceck if cron is up and runing mr nice guy..
lipos, I am sorry about being an idiot earlier, I did not understand how adding what you stated would allow cron to run. I changed as you advised to include -q and --force --debug and it now works. Can you explain why -q or --force --debug made this run?
