Nothing Output from Munin

    I recently installed munin to see how it runs on Ubuntu. I configured it to only monitor the machine it is running on (localhost.localdomain). It appears that both munin and munin-node are running properly, except no reports are showing up on munin's page. There is a page for localhost.localdomain but it contains no reports. Munin has been running for over a day now, and the generated by Munin message at the bottom suggests that it is updating at regular intervals.

    Here is some relevant configuration information

    dbdir   /var/lib/munin
    htmldir /var/www/munin
    logdir  /var/log/munin
    rundir  /var/run/munin

    As you can see, I'm attempting to configure Munin to use just-in-time reporting via CGI by following these instructions without bothering with fast CGI.

    Any suggestions as to why Munin might appear to be doing its job but also appear to be configured to provide 0 reports?

    What's the output of
    ls -la /var/www/munin

    Are there any errors in your logs?

    I don't see any errors. I noticed (after my last post) that cgi-bin/munin-cgi-graph was in /var/lib/cgi-bin (not in /var/www/munin/cgi-bin), so I moved it, chowned it to munin:www-data, and made sure it was executable. Even with restarting munin and/or munin-node this did not solve any problems.

    $ ls -la /var/www/munin

    drwxr-xr-x 4 munin munin    4096 2009-01-07 09:55 .

    I got no output from

    $ sudo grep -i error /var/log/munin/*
    Viewing the logs manually doesn't seem to suggest anything out of the ordinary either. Any suggestions?

    Looks ok as well. Did you disable AppArmor?
