RE: {bb} Larrd apache script

["Homan, Charles" <Charles.Homan@gdc4s.com>]

Hi, Misty,

In lieu of expert advice, here is mine. :-)

I dug into this a little bit, and here is what I have come up with.  Yes, this is a BB-server-side script; it only needs to run on the machine that has your $BBVAR directory.  In apache-larrd.pl, the section starting around line 100 actually connects to the /server-
status page on your apache server (as defined at about line 60 in the %host_h definition section) to gather the data.  It then stuffs the data into an RRD file.  So to have this working you need to have the URL http://myserver.my.dom/server-status?auto accessible from your BB server.  I believe the default for Apache is that this is not enabled.

Here's how to enable the /server-status page.  In your httpd.conf file you need to uncomment the line:
  ExtendedStatus On
and uncomment the section that starts:
  <Location /server-status>
and ends:
  </Location>
Then re-start Apache.

Note that it is considered a (low) security risk to enable this, so you may want to tweak the "Allow from" line to only allow your BB server to access it.

Regards,
Charles
