[smokeping-users] does loss_background do what I think? (and why doesn't it do it?)

[Howard Jones]

Hi folks,

I've just upgraded my 2.4.2 installation to 2.6.9, and noticed on the 
website this nice looking feature where loss is shown as a vertical line 
instead of just the single pixel on the median line. I'm tracking a 
small/infrequent loss problem at the moment, and this would be very 
useful. (I mean, like this:

My 2.4.2 didn't do this, and my 2.6.9 one doesn't either by default. It 
looks like I need:
   loss_background = yes
in the "+ detail" section on the config file, but that doesn't seem to 
make any difference, so...

  1) Is loss_background what produces those vertical lines?
  2) Is there something else I need to do to enable them? (e.g. rrdtool 
version > n, I have 1.2.27 at the moment)

Thanks in advance for any pointers...

Howie
