Poller produces no output

skullone · Post by **skullone** » Wed May 18, 2005 3:40 am

Poller.php isnt producing any output, run from cron, or from the command line.
php poller.php will just return a newline back to the shell, no output of any kind, in logs, or anywhere.
Im running 0.8.6d, on FreeBSD 5.3, with Plesk installed.
I have another FreeBSD 5.4 box running Cacti just fine, had zero problems, but this box simply doesnt execute poller.php or cmd.php
I can add devices, make graphs from those devices, but nothing ever shows up in /rra or /log (well, cacti.log does show some web-access stuff).
Permissions are set correctly, poller.php is run by the webserver user, which has access to /rra and /log (it does write to cacti.log about access to missing rra files)
Im simply at a loss of what to do, the forum doesnt have anyone else with my specific issue.
Thank you!

Start by running "php <path_cacti>/cmd.php" in DEBUG mode. If this provides output, I suspect other issues. Also, check to see that PHP is NOT running in Safe mode.

Also please provide your versions of PHP, MySQL, Apache and provide the output to "php -m".

Thanks,

Versions of software:

/usr/local/psa/mysql/bin/mysql Ver 14.7 Distrib 4.1.7, for unknown-freebsd5.3 (i386)

Server version: Apache/2.0.52

I can execute other PHP scripts from the command line, and they produce various output. But cmd.php and poller.php produce literaly no output, as if they arent even being executed.
The other box, which is similar to this one, doesn't have any problems whatsoever. Im out of ideas

Please verify that your snmpget and snmpwalk paths are accurate and that the Settings->General for Version of SNMP is accurate. It appears that you don't have snmp support built into PHP.

Yah, the paths are correct, as well as the SNMP settings.
Its odd though, I can uncomment the browser checks in the cmd.php and poller.php, and run the script through a browser, and it will run fine, and produce output *sometimes*

The other box which works fine doesn't have SNMP support compiled into PHP either, though.

Edit the database using the following command:

mysql -u root -p cacti
> select count(*) from poller_output;

If you have bocoup lines in that table, then you should:

> truncate table poller_output;
> quit

I have since upgraded PHP on the box, using the Plesk update method, and the problem persists...
I believe the problem is Plesk's fault, and not Cacti.
Plesk is a shitty control panel, this is just fuel for the fire to move away from it.

I think I found this one today as well. A user update apt-get which installed a new RPM for Cacti and in that RPM the following file was overwritten:

poller.php with lib/poller.php

To fix, download the Cacti 0.8.6d source and take the poller.php file from the root of the gz file and overwrite your existing poller.php and you will be back in business.

My problem was that in configuration of cacti another version of php had been used! The problem was solved by taking the correct version!

I am not getting any graph output. Here is output of cmd.php. How do I debug or remedy the Warning?

Thank you!
