This utility is used to calculate Container resource usage.


vzcalc [-v] <CT_ID>

This utility displays what part of server resources Container <CT_ID> is using. An optional –v switch produces verbose output including number of processes, low memory, allocated memory and memory and swap statistics.

For stopped Containers the utility displays promised and maximum values the Container can consume. For running Containers, it also outputs the current values.

The high values of resource usage means that either the server is overcommitted or Container configuration is invalid.
