I need some info on how to get the smokeping.cgi to generate and specifically get put in the right place (in this case /var/www/cgi- bin/). Smokeping seems to be running but there is no output or its going where I cant find it….
I recall being baffled by this at first.
There are two "sides" to Smokeping.
"Side A" runs the probes at appropriate intervals and leaves the
"output" in one or more RRD archives. It needs write access
to the RRD archive area. I like to use a dedicated role account
(user 'smoke', group 'smoke') for this purpose.
"Side B" is run on demand by your web server as a CGI script;
it retrieves data from RRD and creates display pages, including
graphs. It needs read access to wherever the RRD data is, and
write access to a cache area where it creates the display. For
this to work, either your web server must run with group access
to your RRD archive area, or you must have set up suexec so that
the CGI script runs under the smoke account. I include the
'apache' user in the 'smoke' group.
Both sides need to be able to locate and read the configuration
file. ISTR needing to restart either the web server or the
Smokeping daemon (or was it both?) to force configuration changes
to be picked up.
It would be nice (and may very well even be the case, but I didn't
discover how, back whenever) if it were possible to set a couple of
install-time configuration variables and just use
make; sudo make install
I needed to fall back on the old reliables, cp, chmod, install and
the like, and to work out from my logs what was still not working.
I hope this helps.
