Code: Select all

[Mon Oct 17 02:55:59 2011] [error] [client 192.168.1.142] PHP Fatal error:  Call to undefined function api_plugin_hook() in /var/www/cacti/include/global_arrays.php on line 698

line is:

Code: Select all

api_plugin_hook('config_arrays');

Any ideas?
Thx

Your global.php needs to be updated to the correct load order. Take the vanilla global.php from the PIA and install it. With Cacti 0.8.7g+ you should not have to touch global.php anyway. All the changes are in config.php.

TheWitness, I changed global.php to default, change data in config.php

But error still appear...

Edit the <base_path>/include/global.php and see if lib/plugins.php is included before or after include/global_arrays.php.

include/global.php

Code: Select all

/* include additional modules */
include_once($config["library_path"] . "/functions.php");
include_once($config["include_path"] . "/global_constants.php");
include_once($config["library_path"] . "/plugins.php");
include_once($config["include_path"] . "/plugins.php");
include_once($config["include_path"] . "/global_arrays.php");
include_once($config["include_path"] . "/global_settings.php");
include_once($config["include_path"] . "/global_form.php");
include_once($config["library_path"] . "/html.php");
include_once($config["library_path"] . "/html_form.php");
include_once($config["library_path"] . "/html_utility.php");
include_once($config["library_path"] . "/html_validate.php");
include_once($config["library_path"] . "/variables.php");
include_once($config["library_path"] . "/auth.php");

api_plugin_hook("config_insert");

Code: Select all

/* used for includes */
if ($config["cacti_server_os"] == "win32") {
        $config["base_path"]    = str_replace("\\", "/", substr(dirname(__FILE__),0,-8));
        $config["library_path"] = $config["base_path"] . "/lib";
}else{
        $config["base_path"]    = preg_replace("/(.*)[\/]include/", "\\1", dirname(__FILE__));
        $config["library_path"] = preg_replace("/(.*[\/])include/", "\\1lib", dirname(__FILE__));
}
$config["include_path"] = dirname(__FILE__);
$config["rra_path"] = $config["base_path"] . '/rra';

looks good, but I have CentOS, not Win...

Need more information. Can you start logging php to /tmp/php.log. Edit the php.ini file for both Apache and CLI. The setting is 'error_log=/tmp/php.log'. Restart apache afterwards. There needs to be some other error as I have not issues on Debian (Ubuntu), which is where I do most of my testing. RHEL6/CentOS6 is newer, but generally fine.

Dear colleagues,

I got the same error after installation PA v3.0 on fresh installation of Cacti 0.8.7h (tgz) on RHEL6.1 x86_64.

I just installed 0.8.7h (new installation), checked, and after that:

patch -p1 -N < cacti-plugin-arch/cacti-plugin-0.8.7h-PA-v3.0.diff
mysql -u cactiuser --password='password' cacti < cacti-plugin-arch/pa.sql

I didn't noticed any error. But after that http://hostname/cacti/ - HTTP error 500.

Code: Select all

tail -f /var/log/httpd/error_log

Some packets:
httpd-2.2.15-9.0.1.el6.x86_64
php-5.3.3-3.el6.x86_64

Please take a look on this problem.

Thank you in advance.

Install the PIA not from patches, but from the full files.

Dear TheWitness,

Thanks for help. I've just completely reinstall using patched files from tgz and problem is solved for now.

Please update this manual and cacti-plugin-arch/README file, if you please.

And thanks for your work.
