You could use a combination of Host sFlow and mod-sflow on your Apache
web servers:

https://github.com/sflow/mod-sflow

The following article describes how to configure the head-end gmond:

mod-sflow also exports Apache worker pool stats to Ganglia:

mod-sflow also exports URL, referrer, user-agent, response time and
status code information that you can use to derive metrics for each
web service. You could use sFlow-RT to calculate the derived metrics
and proxy them to gmetad:
