I've enabled the apache_ plugins on a munin node:
ln -sv /usr/share/munin/plugins/apache_* /etc/munin/plugins/

After restarting the node with service munin-node restart here are the errors I'm getting:

$ munin-node-configure --suggest 2>/dev/null | grep "apache\|Plugin\|------"
Plugin                     | Used | Suggestions                            
------                     | ---- | -----------                            
apache_accesses            | yes  | no [apache server-status not found. check if mod_status is enabled]
apache_processes           | yes  | no [apache server-status not found. check if mod_status is enabled]
apache_volume              | yes  | no [apache server-status not found. check if mod_status is enabled]

However mod_status is already enabled:

$ a2enmod status
Module status already enabled

And restarting apache doesn't make a difference.

If I try to run the plugins manually here is what I get (I read that getting a U is bad news so at least that is consistent).

$ munin-run apache_accesses --debug
# Processing plugin configuration from /etc/munin/plugin-conf.d/munin-node
# Set /rgid/ruid/egid/euid/ to /110/65534/110 110 /65534/
# Setting up environment
# About to run '/etc/munin/plugins/apache_accesses'
accesses80.value U

$ munin-run apache_processes --debug
# Processing plugin configuration from /etc/munin/plugin-conf.d/munin-node
# Set /rgid/ruid/egid/euid/ to /110/65534/110 110 /65534/
# Setting up environment
# About to run '/etc/munin/plugins/apache_processes'
busy80.value U
idle80.value U
free80.value U

$ munin-run apache_volume --debug
# Processing plugin configuration from /etc/munin/plugin-conf.d/munin-node
# Set /rgid/ruid/egid/euid/ to /110/65534/110 110 /65534/
# Setting up environment
# About to run '/etc/munin/plugins/apache_volume'
volume80.value U

Does anybody know why I'm still getting the server-status not found message and how I can get rid of it?

Updated answer 1

Shane's suggestion was correct about setting a request handler using Location and SetHandler in the apache site. For more information on mod_status please refer to this page

I could verify that munin was effectively making the appropriate requests by looking at /var/log/apache2/access.log where I was getting this: - - [10/Nov/2011:07:24:15 +0000] "GET /server-status?auto HTTP/1.1" 404 7774 "-" "libwww-perl/5.834

In my case setting the Location wasn't enough as I am running a Drupal site and the .htaccess combined with mod_rewrite were rewriting the requests. To fix it, I had to add the following line to my .htaccess

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteCond %{REQUEST_URI} !=/server-status  # <= added this line
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

Please note that this doesn't represent a security problem since access to /server-status is restricted to in the apache site.

Updated answer 2

It appears that adding the Location to the apache site wasn't needed after all since this is already defined in /etc/apache2/mods-enabled/status.conf. Btw, should you want to add the ExtendedStatus On directive, that's in that file that you should do it.

Seems like it's trying to actually make requests to the status module. Do you have a proper config for the status location in your VirtualHost? Something like this:

<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from

Valid point indeed although in my case I also had to do some mod_rewrite work (see updated question with answer) –  user64204 Nov 10 '11 at 7:43

I found solution from Many Ayromlou on this site:

The problem is that these .htaccess rules in wordpress take over server-info and server-status urls activated in apache’s config and return a page not found error. I came across numerous sites that suggested adding a rule like:

  RewriteCond %{REQUEST_URI} !=/server-status

This didn't work for me. I'm not sure if the multisite version of wordpress (which I'm using) is causing this. The rule that worked beautifully is the following:

  RewriteRule ^(server-info|server-status) - [L]

This rule stops the rewrite engine whenever server-info or server-status is parsed as part of the URL.

I found out I could run

$ wget http://localhost/server-status?auto

but not

$ wget

The first one is hitting the default server, the second a virtual server.

So I explicitly added an apache section to /etc/munin/plugin-conf.d/munin-node

env.url   http://localhost:%d/server-status?auto
env.ports 80

and got my munin apache graphs.

I was having the same problem. Here's some more diagnostic steps. Try doing

munin-run apache_processes autoconf

That's a more direct way to see the same error "no (no apache server-status on ports 80)"

Now try doing


For me that's giving 403 Forbidden.

I was also seeing 'client denied by server configuration: /var/www/server-status' in my main apache error log

You getting the same?

For me in fact Shane Madden's answer solved it.

Hi Harry, if you're having the same problem then please vote up the question as it increases the probability of getting answers. –  user64204 Nov 10 '11 at 7:16
Will do, just as soon as I have enough reputation to vote :-) –  Harry Wood Nov 14 '11 at 11:28

If /server-status is forbidden only from you can create VirtualHost configuration for with following content:

<VirtualHost *:80>
    ServerAdmin superadmin@somemail.com
    DocumentRoot /var/www
    <Directory />
            Options FollowSymLinks
            AllowOverride All
    <Directory /var/www>
      Options +FollowSymLinks
      AllowOverride None
      order allow,deny
      allow from all

Here is more detailed explanation
