Name	Description
Primary parameters
numproc	Number of processes and threads.
numtcpsock	Number of TCP sockets.
numothersock	Number of sockets other than TCP.
vmguarpages	Memory allocation guarantee, in pages.
Secondary parameters
kmemsize	Size of unswappable kernel memory, allocated for processes in this container.
tcpsndbuf	Total size of TCP send buffers.
tcprcvbuf	Total size of TCP receive buffers.
othersockbuf	Total size of UNIX-domain socket buffers, UDP and other datagram protocol send buffers.
dgramrcvbuf	Receive buffers of UDP and other datagram protocols.
oomguarpages	The guaranteed amount of memory for the case the memory is “over-booked” (out-of-memory kill guarantee), in pages.
privvmpages	Memory allocation limit, in pages.
Auxiliary parameters
lockedpages	Process pages not allowed to be swapped out (pages locked by `mlock(2)`).
shmpages	Total size of shared memory (IPC, shared anonymous mappings and `tmpfs` objects), in pages.
physpages	Total number of RAM pages used by processes.
numfile	Number of open files.
numflock	Number of file locks.
numpty	Number of pseudo-terminals.
numsiginfo	Number of `siginfo` structures.
dcachesize	Total size of `dentry` and `inode` structures locked in memory.
numiptent	Number of NETFILTER (IP packet filtering) entries.
swappages	Amount of swap space to show in container.
