Adding BiPAC 7401VGPR3 (192.168.1.254) as "Generic SNMP-enabled Host" using SNMP v2 with community "public"
Success - new device-id: (4)

Looks like its its complaining about this section of code. Any ideas on how to fix. Thanks Glenn ?
Software installed - cacti-0.8.7g and cacti-plugin-0.8.7g-PA-v2.8 and autom8-v0.35.

$oldplugins = read_config_option('oldplugins');
$oldplugins = explode(',', $oldplugins);
$plugins = array_merge($plugins, $oldplugins);

If possible, use PIA 2.9
To cure the error, please change function to look like

Code: Select all

/**
 * This function executes a hook.
 * @param string $name Name of hook to fire
 * @return mixed $data
 */
if (!is_array($plugins)) {
	$plugins = array();
}

$oldplugins = read_config_option('oldplugins');
if (strlen(trim($oldplugins))) {
	$oldplugins = explode(',', $oldplugins);
	$plugins    = array_merge($plugins, $oldplugins);
}

Hello,
I still continue to have issues even after changing the fuctions. My include/plugin.php looks as follows
<?php

/*
* Copyright (c) 1999-2005 The SquirrelMail Project Team (http://squirrelmail.org)
* Licensed under the GNU GPL. For full terms see the file COPYING.
*/


global $plugin_hooks, $plugins_system;
$plugin_hooks = array();
$plugins_system = array('settings', 'boost', 'dsstats');

function use_plugin ($name) {
global $config;
if (file_exists($config['base_path'] . "/plugins/$name/setup.php")) {
include_once($config['base_path'] . "/plugins/$name/setup.php");
$function = "plugin_init_$name";
if (function_exists($function)) {
$function();
}
}
}

/**
* This function executes a hook.
* @param string $name Name of hook to fire
* @return mixed $data
*/

if (!is_array($plugins)) {
$plugins = array();
}

$oldplugins = read_config_option('oldplugins');
if (strlen(trim($oldplugins))) {
$oldplugins = explode(',', $oldplugins);
$plugins = array_merge($plugins, $oldplugins);
}


/* On startup, register all plugins configured for use. */
if (isset($plugins) && is_array($plugins)) {
foreach ($plugins as $name) {
use_plugin($name);
}
}


And the error still remains.

PHP Notice: Undefined variable: plugins in /var/www/html/cacti/include/plugins.php on line 30, referer: http://<server ip>/cacti/index.php

Did you import pa.sql into cacti database?

Greetings,

Running in to the same problem even with the suggested changes to plugin.php. Did you ever get this resolved?

Thanks,
jmw

I suggest that you don't change base PIA files. The only file you need to change in Cacti 0.8.7h should be config.php.
