Hi Fabian,

Sorry that you did not receive any reply so far -- your E-mail must have
been lost somewhere in Florian's *and* my mailbox … :-/

Thanks a lot for your patch!

I think it would make sense to merge Openvz.pm and OpenvzFailcnt.pm into
a single plugin (and, possibly, add a config option to configure which
values to collect). Also, that commented out "ignorelist" like feature
could be implemented as a set of config options (similar to the
ignorelist used in some C-based plugins).

Also, please note that in December last year, Jonathan Kolb submitted
another Perl-based OpenVZ plugin collecting interface, cpu, df, load,
process and users statistics by calling vzctl and vzlist. Do you happen
to know if that information is available from /proc (on the host system)
as well? Do you think it would make sense to merge his and your plugins?

Cheers,
Sebastian
