Apache monitoring - Linux, Mac and FreeBSD

The agent can parse the Apache mod_status output to show the current requests per second, idle and busy workers. This metric is only available for paid accounts. It also requires some additional configuration of your Apache server.

This article is outdated and will eventually be removed. See v2 agent Apache monitoring

If you do not wish to monitor Apache then leave the default value in the /etc/sd-agent/config.cfg file and the agent will ignore it.

Note: Apache 1.x is not supported.

1) Configuring Apache

mod_status module

You first need to ensure the mod_status module is installed. This is usually compiled in by default but you may need to uncomment a line in your httpd.conf file: 

#LoadModule status_module modules/mod_status.so

Removing the # will uncomment the line and enable mod_status.


On packaged Ubuntu Apache installations you can enable the mod_status module by using the a2enmod command:

sudo a2enmod status

2) mod_status configuration

Adding the following line to your httpd.conf file will enable the mod_status output. 

ExtendedStatus On

If you restart Apache after adding this line and get an error, check that mod_status has been installed correctly. Look in your Apache error_log for details.

You then need to add in the following lines to set up the location from which the status output can be parsed by the agent: 

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

This will allow the status output to be accessed from http://localhost/server-status (localhost only works on the server itself - replace localhost with your server IP and it will be accessible externally to the IPs you specify in the Allow list, see below).

You should replace PUBLICIP with your server's public IP address. This means you will have 2 IPs listed ( and your public IP). This is so the status output can only be accessed from the server itself. If you wish to access it from your browser, you need to add your IP address in (separated by a space). For example

Allow from

You will now need to restart your Apache web server to allow the changes to take effect. 

3) Agent configuration

You need to enter the URL into the agent /etc/sd-agent/config.cfg file for the apache_status_url option. If your server's IP was then this URL would be Note the ?auto at the end - this is required.



Password protected URLs

If you have password protected your status URL, as of agent 1.11.4 you can provide the agent with a username and password to log in with. Edit your agent config file to add the following 2 lines, specifying your credentials appropriately:



4) Restart agent

Restart the agent to start the monitoring

Problems with server-status not being found

If you get a 404 error or a different page loads when you access the server status, you may have some .htaccess rewrite rules that are preventing Apache from handling the request. You can use this rewrite conditional to ensure requests get processed correctly. This goes above the rewrite rule that is catching the request to server-status 

RewriteCond %{REQUEST_URI} !=/server-status

4) Add graphs

Click the name of your server from the Devices list in your Server Density account then go to the Metrics tab. Click the + Graph button on the right then choose the Apache metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
