vzcalc - calculate resource usage of a container
vzcalc [-v] CTID
This utility displays the share of the host system resources a particular container is using. If the container is running, the current usage is displayed. High utilization values (>100%) mean the system is overloaded (or the container has an invalid configuration). Current Shows the amount of the resources consumed by the container at a given time. Promised Shows the resources soft limit values "promised" for a given container. Max Shows the resources hard limit values "promised" for a given container. If the -v option is specified, the following additional information is also displayed: Low Mem The part of memory residing at lower addresses and directly accessed by the kernel (only makes sense for 32-bit architectures). Total RAM Total memory. Mem+Swap Amount of memory available for applications (both RAM and swap space). Alloc Mem Standard memory allocations made for applications in a container. This is a more "virtual" system resource than RAM or RAM and swap. Num. Proc Number of processes.
-v Display additional information.
Normally, the exit status is 0. On error, the exit status is 1.
