Youbeda is a Perl OVZ complainer. It can look after VEs resources limits and make some actions on failcnt value increase. VEs to look after could be explicitly specified.

Unlike (dead?) Yabeda software Youbeda written in Perl and basically needs only core Perl modules. (However for some actions third-party Perl modules could be needed.)
Originally Youbeda was designed for ALT Linux distros. But probably it can be used with any modern Linux distributions with OVZ-kernels.
