I'm not sure if you understood it right. Prometheus is getting the Performance data via http, that's correct, but it does not use the installed http-server which is serving normal http requests. That obviously would be senseless for the reason you mentioned.

That data provisioning is done by exporters which are tiny lightweight webservers running standalone on the target systems. Like the apache exporter(see here). And well - "lightweight" might be a bit irritating label for a binary with 12 MB size, but as it is go it is statically compiled that's a bit different from a normal dynamically linked executable.

The apache exporter fetches data from apache status module and listens on port 9117 by default.

NAME
apache - Apache hypertext transfer protocol server overview DESCRIPTION
apache consists of a main server daemon, loadable server modules, some additional support utilities, configuration files, and documenta- tion. FILES
The apache HTTPD server is integrated with Solaris. The following files specify the installation locations for apache: /etc/apache Contains server configuration files. A newly-installed server must be manually configured before use. Typically this involves copying httpd.conf-example to the httpd.conf file and making local configuration adjustments. /usr/apache/bin Contains the httpd executable as well as other utility programs. /usr/apache/htdocs Contains the Apache manual in HTML format. This documentation is accessible by way of a link on the server test page that gets installed upon fresh installation. /usr/apache/include Contains the Apache header files, which are needed for building various optional server extensions with apxs(8) /usr/apache/jserv Contains documention for the mod_jserv java servlet module. Documention can be read with a web browser using the url: file:/usr/apache/jserv/docs/index.html /usr/apache/libexec Contains loadable modules (DSOs) supplied with the server. Any modules which are added using apxs(8)are also copied into this directory. /usr/apache/man Contains man pages for the server, utility programs, and mod_perl. Add this directory to your MANPATH to read the Apache man pages. See NOTES. /usr/apache/perl5 Contains the modules and library files used by the mod_perl extension to Apache. /var/apache/cgi-bin Default location for the CGI scripts. This can be changed by altering the httpd.conf file and restarting the server. /var/apache/htdocs Default document root. This can be changed by altering the httpd.conf file and restarting the server. /var/apache/icons Icons used by the server. This normally shouldn't need to be changed. /var/apache/logs Contains server log files. The formats, names, and locations of the files in this directory can be altered by various configuration directives in the httpd.conf file. /var/apache/proxy Directory used to cache pages if the caching feature of mod_proxy is enabled in the httpd.conf file. The location of the cache can also be changed by changing the proxy configuration in the httpd.conf file. ATTRIBUTES

To view the manual pages for the Apache modules with the man command, add /usr/apache/man to the MANPATH environment variable. See man(1) for more information.
