Check OpenVZ Guaranteed Memory
This bash script reports on and checks memory usage of an OpenVZ container, and warns if it exceeds the amount of guaranteed memory.
OpenVZ Linux containers have a notion of 'guaranteed memory' which is typically lower than the total amount of memory available. Since memory is shared among containers, allocating more than the guaranteed amount may eventually fail. This typically results in transient errors which are extremely hard to identify.

Additional detail on the monitored parameters can be found here:
