So you CAN get Apache stats with Collectd using the above URL after you
added "ServerAlias localhost"?

And what about WITHOUT "ServerAlias localhost"?

Do you have ServerAlias localhost in your config? if possible could you

Are you asking why you can get to Apache stats without the above changes,
but not with Collectd?
In other words, why you had to add the above changes to Apache config
before Collectd could get to the Apache stats?

Just trying to clarify the questions.  I'm not sure what the answer is.
 Maybe Toni or one of the other Collectd experts will know.
