Reference 86
AVNUMPROC
Number of processes expected to run in the Virtual
Private Server on average. This is informational
parameter used by utilities like
vzcfgvalidate
in order to ensure configuration correctness.
0…NUMPROC
NUMTCPSOCK
Number of TCP sockets (PF_INET family,
SOCK_STREAM type). This parameter limits the
number of TCP connections and, thus, the number
of clients the server application can handle in
parallel.
40…500
NUMOTHERSOCK
Number of socket other than TCP. Local (UNIX-
domain) sockets are used for communications
inside the system. UDP sockets are used for
Domain Name Service (DNS) queries, as example.
UDP and other sockets may also be used in some
very special applications (SNMP agents and others)
40…500
VMGUARPAGES
Memory allocation guarantee, in pages.
Applications are guaranteed to be able to allocate
memory while the amount of memory accounted as
privvmpages does not exceed the configured
barrier of the
vmguarpages parameter. Above
the barrier, memory allocation is not guaranteed
and may fail in case of overall memory shortage.
1725…107520
KMEMSIZE
Size of unswappable kernel memory, allocated for
internal kernel structures for the processes of a
particular VPS. Typical amounts of kernel memory
is 16…50 Kb per process.
798720…13148160

851968…14024704
TCPSNDBUF
Total size of send buffers for TCP sockets – amount
of kernel memory, allocated for data sent from
application to TCP socket, but not acknowledged
by remote side yet.
159744…5365760-
262144…10458760
TCPRCVBUF
Total size of receive buffers for TCP sockets.
Amount of kernel memory, received from remote
side but not read by local application yet.
159744…5365760-
262144…10458760
OTHERSOCKBUF
Total size of UNIX-domain socket buffers, UDP
and other datagram protocols send buffers.
61440…1503232-
163840…4063232
DGRAMRCVBUF
Total size of receive buffers of UDP and other
datagram protocols.
32768…262144
OOMGUARPAGES
Out-of-memory guarantee, in pages. Any VPS
process will not be killed even in case of heavy
memory shortage if current memory consumption
(including both physical memory and swap) until
oomguarpages barrier is not reached.
1725…107520
LOCKEDPAGES
Memory not allowed to be swapped out (locked
with the
mlock() system call), in pages (one page
is 4 Kb).
4…4096
SHMPAGES
Total size of shared memory (including IPC, shared
anonymous mappings and
tmpfs objects),
allocated by processes of particular VPS, in pages.
512…16384
PRIVVMPAGES
Size of private (or potentially private) memory,
allocated by an application. Memory that is always
shared among different applications is not included
in this resource parameter.
