An Enum representing a resource type

Variants

CpuTime
[−]

CPU time, in seconds

DataSize
[−]

datasize, in bytes

StackSize
[−]

stack size, in bytes

from the FreeBSD Handbook Chapter 13.13 - Resource Limits:

The maximum size of a process stack. This alone is not sufficient to limit the amount of memory a program may use, so it should be used in conjunction with other limits.

CoreDumpSize
[−]

coredump size, in bytes

from the FreeBSD Handbook Chapter 13.13 - Resource Limits:

The limit on the size of a core file generated by a program is subordinate to other limits on disk usage, such as filesize or disk quotas. This limit is often used as a less severe method of controlling disk space consumption. Since users do not generate core files and often do not delete them, this setting may save them from running out of disk space should a large program crash.

MemoryUse
[−]

resident setsize, in bytes

MemoryLocked
[−]

locked memory, in bytes

from the FreeBSD Handbook Chapter 13.13 - Resource Limits:

The maximum amount of memory a process may request to be locked into main memory using mlock(2). Some system-critical programs, such as amd(8), lock into main memory so that if the system begins to swap, they do not contribute to disk thrashing.

MaxProcesses
[−]

number of processes

OpenFiles
[−]

File descriptor table size

VMemoryUse
[−]

address space limit, in bytes

PseudoTerminals
[−]

number of PTYs

SwapUse
[−]

swapspace that may be reserved or used, in bytes

NThreads
[−]

number of threads

MsgqQueued
[−]

number of queued SysV messages

MsgqSize
[−]

SysVmessagequeue size, in bytes

NMsgq
[−]

number of SysV message queues

Nsem
[−]

number of SysV semaphores

NSemop
[−]

number of SysV semaphores modified in a single semop(2) call

NShm
[−]

number of SysV shared memorysegments

ShmSize
[−]

SysVshared memory size, in bytes

Wallclock
[−]

wallclock time, in seconds

PercentCpu
[−]

%CPU, in percents of a single CPU core

ReadBps
[−]

filesystem reads, in bytes per second

WriteBps
[−]

filesystem writes, in bytes per second

ReadIops
[−]

filesystem reads, inoperations per second

WriteIops
[−]

filesystem writes, in operations persecond
