[collectd] collectd-4.9.1 and perl OpenVZ plugin

[Sergey]

Hello.

I try to use perl OpenVZ plugin, but collectd is not started:

Sep  1 13:02:47 collectd[31662]: perl: Initializing Perl interpreter...
Sep  1 13:02:47 collectdmon[31661]: Warning: collectd terminated with exit status 2
Sep  1 13:02:47 collectdmon[31661]: Warning: restarting collectd

config:

<Plugin perl>
        BaseName "Collectd::Plugin"
        LoadPlugin OpenVZ
</Plugin>

I can see error "collectd[941]: perl: init_pi: Unable to bootstrap Collectd:
Can't locate Devel/OpenVZ.pm in @INC" when I added 'EnableDebugger "OpenVZ"'.
Why is "Devel" used ?
