OBS If you receive some FAILED messages then PA won't work fine. I recommend you to Re-install cacti.

3.- Apply patches and fix some changes
Apply the Diff file

root@server:/var/www/cacti# patch -p1 -N < cacti-plugin-0.8.7c-PA-v2.3.diff

Now, If you go to Cacti Web site you will see something like this:


So, You have to go to include/global.php file and update like this:

root@server:/var/www/cacti# vim include/global.php

Change from:

$config['url_path'] = '/';

to:

$config['url_path'] = '/cacti';

Now Cacti console is fixed but we need to update cacti DB

4.- Update DataBase
Cacti DB works with 48 TABLES but it will use 52 whit PluginArchitecture

root@server:/var/www/cacti# cd pa/
root@server:/var/www/cacti/pa# mysql -uroot -pRootPasswd noc <>

TABLES:

• plugin_hooks
• plugin_db_changes
• plugin_realms
• plugin_config

5.- Update Realm Permissions for "admin"
Enable Plugin Management for admin user
Go to:
console-> User Management -> Select Admin -> Realm Permissions
