Post :::SOLVED::: Cacti Plugin Arch Problems - Ubuntu Server 8.04
Greetings,

I wanted to try my hand at the Cacti Plugin Architecture and use the Nagios plugin. I have noticed that there are issues around the board regarding Ubuntu 8.04 installations.

Using prepatched files I receive this error in browser:

Invalid PHP_SELF Path

When I go through the process of patching I receive a different error:

Fatal error: Call to undefined function api_plugin_hook() in /usr/share/cacti/site/include/global_arrays.php on line 620

Each case that references these errors in the forum is running Ubuntu. I pray that someone can help track down the source of this issue. Thanks in advance.

Brian

Not sure if this helps...

I had the same problem with the Invalid PHP_SELF Path problem after I did the pre-patch method.

I solved it by changing some lines in the global.php file.

See this article: http://www.askaboutphp.com/tutorials/42/cacti-ubuntu-cacti-plugin-invalid-php_self-path.html

but i didn't do the patch method.

Post Almost there...
I followed the instructions very closely. The site does come back up, but I lose most of the functionality. The links are no longer pointing to my /cacti/ directory, but attempting to link directly from the root of the site. I think I can track that down. I'll let you know if I'm successful.

Thanks for the heads up!

Post Solved
Once all of the files have been loaded into the appropriate directories there are a few needed edits to the /usr/share/cacti/site/include/global.php file.

Choose your favorite editor and make these changes:

At line 56:
$config[’url_path’] = ‘/’;
change it to:
$config[’url_path’] = ‘/cacti/’;

At line 104:
$config["rra_path"] = $config["base_path"]."/rra";
change it to:
$config["rra_path"] = "/var/lib/cacti/rra";

At line 128 where it says:
$_SERVER["PHP_SELF"]
change it to:
basename($_SERVER["PHP_SELF"])

At line 201:
include($config["library_path"]."/adodb/adodb.inc.php");
change it to:
include("/usr/share/php/adodb/adodb.inc.php");

Thank you 'diagnostix' for the link, and thanks to whoever wrote the fix at:
http://www.askaboutphp.com/tutorials/42 ... -path.html

Sincerely,

Brian

Are you using the RPM / APT-Get / Packaged version of Cacti that does not come from the Cacti site? If so it is not supported by the Plugin Architecture.

Hey Nationals,

Thank you very much for the patch, I was able to install it on my Ubuntu 8.04 Server (Apt-get Cacti edition) without any problems.

I am trying to track down a plugin permission problem I have had since then and was curious if you have had the same problem.

When you create a limited user in Cacti and give them realm permissions of only "View Graphs" and "Monitor". Do you have a problem with that user seeing extra tabs?

In this case the new users see some of my other plugins tabs even though they don't have realm permissions to it. They can not access it, they only see the tab on top.

The other issue is, if I had a new plugin (in this case, "Superlinks") I can not add it for the limited users to see.

Just wanted to check if you have a similar problem.

For kicks, here is my server info:

I have Ubuntu 8.04 Server and install using:

apt-get install cacti

I downloaded your patch it and it works. I then downloaded the monitor plugin and I have the option to "monitor host" now, but when I click save, at the top, I get:

Error: Save Failed.


Does this point to a permissions error? I updated the global.php file after doing the patch.

I should also note that even if I uncheck the monitor option, it still says the error about save failed. Its not until I comment out that plugin in the global.php file that I can add or update a host again.
