[smokeping-users] Smokeping graphs not showing up

[Dago Pacheco]

Ok ... I managed to troubleshoot my problem and I get to a solution.
The problem was that "imgurl" config value was incorrectly set.  What I 
had was "/opt/smokeping/cache/".  With this value my web server couldn't 
load images, because it was unable to find that dir.  What I did to 
solve this was to create a symlink from smokeping web root to smokeping 
cache dir, like this:

    ln -s /opt/smokeping/cache /<webdocs_root>/smokeping/cache


And then set "imgurl" config value to "cache" (which is the relative 
path for smokeping.cgi .... absolute value should be 
http://smokeping.some.domain/cache).  And that's it, graphs start to 
show up.

I'd like to point out that official installation instruction are quite 
tricky, and can lead confusions and, consequently, unnecessary 
troubleshooting situation, like my case. I think that more detailed 
instructions which, at least, shows up some default example settings, 
would save a lot of time.

Thanks everybody.
