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'

I read this thread now
http://sourceforge.net/mailarchive/forum.php?thread_name=468 93903.2010901%40nerim.net&forum_name=munin-users
, and did this:
munin-run

Warning: Unknown config option in "/etc/munin/plugin-conf.d/munin-node" under "[vebc*]": env.config at /usr/sbin/munin-run line 619, <IN> line 19.

 less -N `which munin-run`
[...]
    619             warn "Warning: Unknown config option in \"$dir/$file\" under \"[$service]\": $_";[...]

I commented that line in /etc/munin/plugin-conf.d/munin-node out:

# env.config

but I still get:

[...]

ERROR: Could not execute plugin (plugin doesn't exist?).

 less -N `which munin-run`
[...]
    321         next unless ($file =~ /^$ARGV[0]$/);

I also tried to debug with telnet:

# telnet localhost  4949
Trying 127.0.0.1...

Escape character is '^]'.
# munin node at pv10.ncsrv.de
fetch vebc_numfile_privvmpages_lockedpages_001
.
config  vebc_numfile_privvmpages_lockedpages_001
# Unknown service
.
Connection closed by foreign host.

Hmmm... it's an unknown service, why?

Any clues?

I managed to solve the problem:

Quote:

# su root -c "cat /proc/user_beancounters"

I had to change every appearance of myid to uid, and rename the symlinks from *_001 to *_33189

mv /etc/munin/plugins/vebc_numfile_privvmpages_lockedpages_001 /etc/munin/plugins/vebc_numfile_privvmpages_lockedpages_33189
