[smokeping-users] New browsers do not show graphs

[Thorstensen, Kjetil]

Hi.

I found the problem - I'd love to say that it was by design, but more a coincidence.

I stumbled on the properties of the graphics - the path was a URL where the smokeping server was referenced with its hostname only, not IP or FQDN. This cannot be resolved in my new environment. After some searching I found the setting in the top of the smokeping config file - along with the definitions of the monitored hosts:
# 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 = /var/www/html/smokeping/img
imgurl   = http://10.XXX.XXX.91/smokeping/img
datadir  = /usr/local/smokeping/var
piddir  = /usr/local/smokeping/var
cgiurl   = http://10.XXX.XXX.91/smokeping.cgi
smokemail = /usr/local/smokeping/etc/smokemail
tmail = /usr/local/smokeping/etc/tmail
# specify this to get syslog logging

When I swapped the hostname for the IP it work fine - and much quicker too.

/etc/httpd/conf/httpd.conf:

<Directory "/var/www/html">
    Options Indexes FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

There are no 404's though, because I get the sidebar with the list of monitored hosts, but just the "broken page" icon on the right:

(I restored the list as a recipient; see far below for Kjetil's response direct to me)

I think you must have set up web server incorrectly. Here's some bits of my apache vhost config

        DocumentRoot /usr/local/smokeping/htdocs
        <Directory      /usr/local/smokeping/htdocs>
                Options +ExecCGI
                Addhandler fcgid-script *
                Order           allow,deny
                Allow from      192.168.0.0/24<http://192.168.0.0/24>
                DirectoryIndex  smokeping.fcgi
        </Directory>

        Alias   /cache   /usr/local/smokeping/cache
        <Directory      /usr/local/smokeping/cache>
                Allow from      all
        </Directory>

That should stop a bunch of the 404s. Don't forget to kill all the fcgi processes after reloading apache ("apachectl graceful" for example).

what do you see in the web logs when using a "broken" browser?
