Bug 225671 – munin has no plugins available, neither incl. in the ~amd64 munin-ebuild, nor separately. Therefore doesn't work

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gordon Pritchard 2008-06-09 21:05:13 UTC]

Edit /etc/portage/package.keywords, to accept unstable net-analyzer/munin-1.3.4. Emerge 'munin', run "emerge --config net-analyzer/munin" per ebuild-message.  Watch the cron-error-emails arrive, every 5min, whether or not munin-node is running. 

Reproducible: Always

Steps to Reproduce:
1.  emerge unstable (~amd64) net-analyzer/munin.  Installs net-analyzer/munin-1.3.4 at time of reporting.
2.  emerge --config net-analyzer/munin
3.  cron-error-emails arrive, every 5min thereafter

Actual Results:  
Cron-error-message, received via email:

HTML::Template::param() : attempt to set parameter 'groups' with a scalar - parameter is not a TMPL_VAR! at /usr/libexec/munin/munin-html line 162

Also:
# su -s /bin/bash munin
$ munin-cron

produces:
HTML::Template::param() : attempt to set parameter 'groups' with a scalar - parameter is not a TMPL_VAR! at /usr/libexec/munin/munin-html line 162

Expected Results:  
Should have nice munin-graphs

edit /var/lib/munin/crontab and comment out the cron-line which runs munin-cron every 5min.  This stops the mail-messages, at least.

Fixed in CVS. I patched it to have a more useful error message.

The actual source of the error is that your munin-update has not generated any RRD files yet, so munin-graph has not generated any graphs, and thus munin-html has no input data to generate pages for.

The full set of instructions does tell you to symlink plugins into /etc/munin/plugins/ before you start munin-node.

Thanks for the speedy response!

When will this fix hit the tree?
