Get Stats
To get statistics, you'll need to potentially modify your Apache configuration. For Ubuntu, it's as easy as a2enmod status (and reload the server with service apache2 reload)
Cli
# Using wget isn't advised because you'll get html output
wget http://localhost/server-status -O -
# Ubuntu
apache2ctl fullstatus
# Older/RedHat
apachectl fullstatus

e.g. http://example.com/server-status?auto
