[hobbit] multiple apache instance trending question

[Charles Jones]

You can do that via something like this in bb-hosts:

page Apaches
0.0.0.0 Website1  # http 
apache=http://vhost1.yourdomain.com/server-status?auto 
TRENDS:*,apache:apache|apache1|apache2|apache3
0.0.0.0 Website2  # http 
apache=http://vhost2.yourdomain.com/server-status?auto 
TRENDS:*,apache:apache|apache1|apache2|apache3
....

This would allow you to track the various apache graphs for each of your 
sites you have running (available in the trends column)
