Apache2 (CGIs) y Nagios

["Adrià" <adriagm@gmail.com>]

Hola, buenos días,

tenemos una máquina con, entre otras cosas, Apache2 y Nagios para
monitorizar unos servidores.
Por separado ambos funcionan, pero a la hora de ver en tiempo real la
actividad de Nagios vía web es cuando aparecen los problemas.
Y dado que en Apache no estoy muy puesto, a ver si me podeis echar una
mano (gracias antes que nada). Os cuento brevemente:
Si intento consultar algo desde la web de Nagios, me dice: Whoops!
Error: Could not read host and service status information!

Al iniciar Apache dice:
gwmon:/home/admin# /etc/init.d/apache2 reload
Reloading web server config...[Mon Feb 05 12:18:07 2007] [warn] The
ScriptAlias directive in /etc/apache2/sites-enabled/nagios/apache.conf
at line 11 will probably never match because it overlaps an earlier
ScriptAlias.
[Mon Feb 05 12:18:07 2007] [warn] The ScriptAlias directive in
/etc/apache2/sites-enabled/nagios/apache.conf at line 12 will probably

[Mon Feb 05 12:18:07 2007] [warn] The Alias directive in

[Mon Feb 05 12:18:07 2007] [warn] The Alias directive in

done.

Dentro del fichero mencionado, la configuración debería ser la buena
(no la he modificado):
gwmon:/home/admin# cat /etc/apache2/sites-enabled/nagios/apache.conf

# BEGIN FOR NAGIOS
# Bug 160681 and 162986 say that the ScriptAlias should be
#       /cgi-bin/nagios
# but some reports, 164925, (and the default config) say
# that it should be
#       /nagios/cgi-bin
# Anyone having problems with this, PLEASE dig deeper in WHY
# it won't work for you...
#
# I'm enabling BOTH, just to be sure!
ScriptAlias /cgi-bin/nagios /usr/lib/cgi-bin/nagios
ScriptAlias /nagios/cgi-bin /usr/lib/cgi-bin/nagios
<DirectoryMatch /usr/lib/cgi-bin/nagios>
       Options ExecCGI

       AllowOverride AuthConfig
       Order Allow,Deny
       Allow From All

       AuthName "Nagios Access"
       AuthType Basic
       AuthUserFile /etc/nagios/htpasswd.users
       require valid-user
</DirectoryMatch>

# Where the stylesheets (config files) reside
#
Alias /nagios/stylesheets /etc/nagios/stylesheets

# Enable this ScriptAlias if you want to enable the grouplist patch.
# See http://apan.sourceforge.net/download.html for more info
# It allows you to see a clickable list of all hostgroups in the
# left pane of the Nagios web interface
#ScriptAlias /nagios/side.html /usr/lib/cgi-bin/nagios/grouplist.cgi

# Where the HTML pages live(d)
Alias /netsaint /usr/share/nagios/htdocs
Alias /nagios /usr/share/nagios/htdocs
<DirectoryMatch /usr/share/nagios/htdocs>
       Options FollowSymLinks

       AllowOverride AuthConfig
       Order Allow,Deny
       Allow From All

       AuthName "Nagios Access"
       AuthType Basic
       AuthUserFile /etc/nagios/htpasswd.users
       require valid-user
</DirectoryMatch>
# END FOR NAGIOS

Disculpad el mail tan largo, pero creo que tenía que pegar la configuración.

Bueno, y si alguien me puede echar una mano, pues le estaré muy agradecido.

Saludos.
