Hello,

I got problems to get graphs with the wiki plugin for munin:
http://wiki.openvz.org/Monitoring_openvz_resources_using_mun in

How can I debug this? There are no *.png generated, but html files, without much content:

$ lynx --dump  /var/www/munin/localdomain/localhost.localdomain-vebc_numfile_privvmpages_lockedpages_001.html

How can I get /proc/user_beancounters monitored?

I hope, this is not due to incompatibilities between the wiki-munin-plugin for OpenVZ and the use for virtuozzo. I'm using a vserver virtualized by virtuozzo instead of OpenVZ.

EDIT: This is the output of the plugin itself:
# /etc/munin/plugins/vebc_numfile_privvmpages_lockedpages_001 config yes
graph_title beancounter for VE001: numfile privvmpages lockedpages
graph_category VE001
graph_info 'VE bean counters info'
