Monitor apache using mod_status on Ubuntu

Apache installation on Ubuntu Linux automatically installs mod_status also. mod_status can be used to view server activities and performance from a web interface. Here are quick steps to get started with mod_status.

First ensure if you have mod_status installed. Assuming you have apache2 installed run the following on command line.
```
$ apache2ctl -M | grep status
status_module
```
Note that apache2ctl -M lists all apache loaded modules.

mod_status comes with a default config (/etc/apache2/mods-available/status.conf) which is only accessible from localhost. Here is how the config entry looks like:

...
        <Location /server-status>
                SetHandler server-status
                Require local
                #Require ip 192.0.2.0/24
        </Location>
...

To setup mod_status remote access with basic http auth add the following apache config. Note that you will have to create /etc/auth-file and a user in it. You can follow steps mentioned in tutorial Apache – add basic auth to a location or directory.
```
<IfModule mod_status.c>
  <Location /my-server-status>
    SetHandler server-status
    AuthType Basic
    AuthName "Restricted Resource"
    AuthBasicProvider file
    AuthUserFile /etc/auth-file
    Require valid-user
  </Location>
</IfModule>
```
In case you are using wordpress or similar such software where every request is routed to index.php using .htaccess, you can add the following config to .htaccess before RewriteRule entry
```
...
RewriteCond %{REQUEST_URI} !^/my-server-status$
RewriteRule . /index.php [L]
```
Now restart apache and access the /my-server-status page. You should be able to see the server status page with all requests being handled by Apache at that time. Here is how it will look like:
