Cacti failing to poll - Cacti cacti-1.1.19-2 on CentOS 6

[Samtech]

I am relatively new to cacti and linux. I have installed cacti on centos 6. I have been able to install but the graphs are not polling despite the equipment being detected on cacti.

I have tried to perform various changes as read on forums to no avail. All help is welcome

Have you got a cron job setup to run the poller.php?

[Samtech]

Not sure

I used this guide during the installation

As indicated, I am relatively new to linux

Setting Cron for Cacti
Open file /etc/cron.d/cacti.

Code: Select all

# vi /etc/cron.d/cacti

Uncomment the following line. The poller.php script runs every 5mins and collects data of known host which is used by Cacti application to display graphs.

Code: Select all

#*/5 * * * *    cacti   /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

This is the section that matters. However, what they have done is left a # at the front of the cron to stop the scheduler kicking in before you've fully installed cacti. You need to edit /etc/cron.d/cacti and remove that hash prefix for the poller to actually kick in.

Yes I had done that earlier but still it did not work

OK, what is appearing in the log files? Are there any errors or warnings?

[Samtech]

How can i check on that?

Just curious, did you change all the Timezone settings in /etc/php.ini and /etc/my.cnf ?

Also, you can check if the rrd files are actually updated ?

You can do this by going to the Console, then in the Management section choose "Data Sources". Select a data source there and on the next script click on the "Turn On Data Source Info Mode". You will see a new section with "RRD File Information" stating the full path to the rrd file as well as the last_update time.

The timezone settings have not been changed


"Turn On Data Source Info Mode" does not show any extra info. Page remains the same with the feature turned on or off
