[SOLVED] Cron out of sync with Poller Interval cacti 0.8.7a

[tomines]

Hi I am new to cacti and I just installed version 0.8.7a last week. I'm having problems with my poller running. When I run it manually as the cacti user I get the following.

--begin cut

#php /var/www/html/cacti/poller.php

12/03/2007 01:23:26 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '300' seconds, with a maximum of a '300' second Cron, but 489 seconds have passed since the last poll!

--end cut

I've read all the posts in regards to this and here are my notes.

- The poller interval and cron interval are both set to 5 minutes

- This was compiled and not installed from a package and only one instance of the cron is running at a time

- made sure poller.php variable $cron_interval is set to 300

- rrd files time stamps are NOT getting updated

- there was a suggest to install a new <functions.php>. This was done

- I get the following from mysql

- select count(*) from poller_output;

+----------+

| count(*) |

+----------+
| 0 |
+----------+

1 row in set (0.00 sec)

- also did this in mysql

truncate poller_output;

- memory settings in my php.ini is set to 128M

Please help

Hi

did you add a cron job to run the poller every 5 minutes ?

[tomines]

Yeah I actually got this fixed last night. The problem was actually with my crontab. For whatever reason when I set this up to run as cacti in roots crontab the poller did not work

*/5 * * * * cacti php /var/www/html/cacti/poller.php > /dev/null 2>&1

The following below worked when I ran it directly from the cacti user's crontab.

*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1

The is on Fedora 7

I can't get a cron job to run. When I run it in Webmin no errors are outputted.

*/5 * * * * root /usr/bin/php /usr/share/cacti/cactipoller.php >/dev/null 2>&1

I'm really stuck. I've also tried everything in this thread.

That was a mistake, sorry. This is what it's suppose to be but it's not working.

Please read the second link of my signature. There's a chapter on crontab problems that may help

Thanks

I checked your link and added a new crontab entry

[gandalf]

[brokentongue]

Thank you. It's working now.

Maybe this will help someone.

I didn't have cron running. To check to see if cron is running enter the command

I've added this hint to the HowTo

it's nt solved for all....
I use RH5.2 and your way of configurating cron was not working for me.
Here's whet I did though:

- I logged to root (I'm running this cron job form root account)

- run crontab -e

- add (you migh want to update the paths with yours)

[lipos]

OK!

It's working for me now.. Overall here's my configuration

crontab -e

and put

Code:


*/5 * * * * php -q /var/www/html/cacti/poller.php --force --debug >> /var/local/log/poller.log 2>&1



Check the cron command that I gave you above. It's should show some more logs that your command does. Let me know.

My problem was cause by cron command. I added root before php -q.
I didn't get any logs before I pointed it to a file ..soooo check it!

Cheers...
