I'm not inclined to install an application which relies on HTTP at the data transport layer to monitor a LAMP application where HTTP and apache2 are at the core of the problem. However, for a different scenario, an HTTP-transport based monitoring system might be "just the ticket".
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.
