[HowTo] Get some nice Server graphs with Munin

[DaSilva]

I started the script from the cronjob (/usr/bin/munin-cron --force-root) manually and it worked.
After that I set "chown -R munin /var/www/munin/*" and waited five minutes but nothing happens.
Then I logged in as user munin with "su - munin --shell=/bin/bash" and ran "/usr/bin/munin-cron" and I got many errors like

"Error writing to /var/run/munin/munin-html.lock, wrong permissions at /usr/share/perl5/Munin.pm line 356."

so i set "chown munin /var/run/munin/*" as root and ran "/usr/bin/munin-cron" again with no errors.
Now only the *.html files were updated, the graphic files not.
After six minutes I waited for the cronjob (should work now) but no files were changed or had another time stamp.
So where could be the problem?
Thanks.
