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.

Check your permissions on /var/lib/smokeping. My chown permissions
are: smokeping:smokeping, except for _cgi where they are
smokeping:www-data. The smokeping user must be able to r/w to the .rrd
files.

Hi everybody:
I'm having troubles setting up smokeping. I installed version 2.6.8
from source on a CentOS 5.7 machine. Compilation process finished
without problems and smokeping is started as a daemon correctly (I also
started in debug mode, and there where no errors). The web page is
rendered correctly but graphs doesn't show up. I checked imgcache dir,
and png files are correctly generated.
As I said, I compiled smokeping from sources following official
documentation from
http://oss.oetiker.ch/smokeping/doc/smokeping_install.en.html.
This are my General configuration values
*** General ***
owner = Aministrador Servidores
contact = some@mail
mailhost = some.mail.host
sendmail = /usr/sbin/sendmail
# NOTE: do not put the Image Cache below cgi-bin
# since all files under cgi-bin will be executed ... this is not
# good for images.
imgcache = /opt/smokeping/cache
imgurl = ../cache
datadir = /opt/smokeping/data
piddir = /opt/smokeping/var
cgiurl = http://smokeping.some.host/smokeping.cgi
smokemail = /opt/smokeping/etc/smokemail
tmail = /opt/smokeping/etc/tmail
# specify this to get syslog logging
syslogfacility = local7
# each probe is now run in its own process
# disable this to revert to the old behaviour
concurrentprobes = yes
changeprocessnames = yes
This is the folder list from /opt/smokeping
[root@isaac:/opt/smokeping]# ll
total 40
drwxr-xr-x 2 root root 4096 feb 17 11:44 bin
drwxr-xr-x 4 apache apache 4096 feb 17 16:04 cache

drwxr-xr-x 6 root root 4096 feb 17 11:41 thirdparty
drwxr-xr-x 2 root root 4096 feb 17 13:04 var
I tried changing permissions and imgcahe and imgurl values, but didn't work.
Don't know what to do. Any advise would be appreciated.
Thanks :)
