Project Notes
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: http://wiki.openvz.org/UBC_primary_parameters#vmguarpages The actual code is managed in the following GitHub rebository - please use the Issue Tracker to ask questions, report problems or request enhancements. https://github.com/acch/nagios-plugins
