Bug 302611 – net-analyzer/pnp4nagios-0.6.2 error after upgrade

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Clemente Aguiar 2010-01-28 11:43:49 UTC]

I have upgraded pnp4nagios from 0.4.14 to 0.6.2, and now when I try to see the graphs in Nagios I get the following error:

The requested URL /pnp4nagios/graph was not found on this server.

I think that this has to do with the path configuration differences between the ones selected by the Gentoo distribution and the default of pnp4nagios.
see http://docs.pnp4nagios.org/pnp-0.6/upgrade



Reproducible: Always

Postinst-Message should be changed to

Alias /pnp4nagios /usr/share/pnp
...
...

We should also add the link from Clemente to the message because you have to delete the xml-files from perfdata-directory manually if you upgrade from version 0.4.

I have upgraded from 0.4.14 to 0.6.2 and am seeing this error as well.  I have the correct Alias in my apache configs (as noted in Comment #1) and have manually removed all .xml files from the perfdata directory.  All post-install checks are green when I go to http://localhost/pnp4nagios after the upgrade.  Where else should I look for a problem?

/etc/pnp/config.php:
$conf['use_url_rewriting'] = 0;

did you set this to 1? To use url_rewriting you have to change your apache config... (i did not use this, so i did not create a working config).

That is set to 1; are the required changes for apache documented somewhere?  I am allowing mod_rewrite (and pnp4nagios' environment test gives me a "Pass" for the "Apache Rewrite Module" check).

[Comment 6 Jon Sippel 2010-02-01 18:48:12 UTC]

I just got 0.6.2 working by disabling the 'use_url_rewriting' option in /etc/pnp/config.php and setting the action_url to /pnp4nagios/index.php/graph?host=$HOSTNAME$ in my Nagios template definitions.

I don't have a preference if the urls are rewritten or not, so I'm okay with this configuration going forward.  Hopefully this will help get the ebuild sorted out.

Full Apache-Config (including mod_rewrite) should be

        Alias /pnp4nagios /usr/share/pnp/
        <Directory /usr/share/pnp>
                AllowOverride AuthConfig
                Order allow,deny
                Allow from all
                <IfModule mod_rewrite.c>
                        # Turn on URL rewriting
                        RewriteEngine On
                        Options FollowSymLinks
                        # Installation directory
                        RewriteBase /pnp4nagios
                        # Protect application and system files from being viewed
                        RewriteRule ^(application|modules|system) - [F,L]
                        # Allow any files or directories that exist to be displayed directly
                        RewriteCond %{REQUEST_FILENAME} !-f
                        RewriteCond %{REQUEST_FILENAME} !-d
                        # Rewrite all other URLs to index.php/URL
                        RewriteRule .* index.php/$0 [PT,L]
                </IfModule>
        </Directory>

This configuration is from sample-config-directory which is included in the source. maybe we can add some useflags (apache, lighttpd) and add the sample config for automatic installation and dependency-checks?

maybe I'll find time to do this in the next days...

Did so for 0.6.3 (USE="apache2" and -D PNP in /etc/conf.d/apache2).
