Frequently getting the below shown poller Error

[tkrishnamurthy]

Please go through the screenshot of the cacti log file showing the poller error which is becoming increasingly frequent. I have checked the database and it is working fine.

I appreciate any help in resolving this.

From SYSTEm STATS, you will see that there were two pollers running at the same time (12:00). Please check your crontabs. I suspect there's a second entry for cacti in one of those crontabs

Thanks for your reply

I did checked the Cron and there is only one poller running.

Sorry to lay pressure on this; but which crontabs did you check?

I did checked the crontab for user cacti and for the root there is nothing in there and I have added the following entry into /etc/crontab file which will run every 5 minutes
*/5 * * * * cacti php /var/www/cacti/poller.php > /dev/null 2>&1

[gandalf]

What about /etc/cron.d/cacti? Is there such a file?
Then, you may try replacing

Code: Select all

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

by

Code: Select all

*/5 * * * * cacti php /var/www/cacti/poller.php > /var/www/cacti/log/poller.log 2>&1

Please study output of that file and return your info here
