The options are as follows: .Bl -tag -width indent .It Fl a Ar rule Add .Ar rule to the RCTL database. .It Fl l Ar filter Display rules applicable to the process defined by .Ar filter . Note that this is different from showing the rules when called without any options, as it shows not just the rules with subject equal to that of process, but also rules for the user, jail, and login class applicable to the process. .It Fl r Ar filter Remove rules matching .Ar filter from the RCTL database. .It Fl u Ar filter Display resource usage for a subject .Po .Sy process , .Sy user , .Sy loginclass or .Sy jail .Pc matching the .Ar filter . .It Fl h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte. .It Fl n Display user IDs numerically rather than converting them to a user name. .El .Pp Modifying rules affects all currently running and future processes matching the rule. .Sh RULE SYNTAX Syntax for a rule is subject:subject-id:resource:action=amount/per. .Pp .Bl -tag -width "subject-id" -compact -offset indent .It subject defines the kind of entity the rule applies to. It can be either .Sy process , .Sy user , .Sy loginclass , or .Sy jail . .It subject-id identifies the .Em subject . It can be a process ID, user name, numerical user ID, login class name from .Xr login.conf 5 , or jail name. .It resource identifies the resource the rule controls. See the .Sx RESOURCES section below for details. .It action defines what will happen when a process exceeds the allowed .Em amount . See the .Sx ACTIONS section below for details. .It amount defines how much of the resource a process can use before the defined .Em action triggers. Resources which limit bytes may use prefixes from .Xr expand_number 3 . .It per defines what entity the .Em amount gets accounted for. For example, rule "loginclass:users:vmem:deny=100M/process" means that each process of any user belonging to login class "users" may allocate up to 100MB of virtual memory. Rule "loginclass:users:vmem:deny=100M/user" would mean that for each user belonging to the login class "users", the sum of virtual memory allocated by all the processes of that user will not exceed 100MB. Rule "loginclass:users:vmem:deny=100M/loginclass" would mean that the sum of virtual memory allocated by all processes of all users belonging to that login class will not exceed 100MB. .El .Pp A valid rule has all those fields specified, except for .Em per , which defaults to the value of .Em subject . .Pp A filter is a rule for which one of more fields other than .Em per is left empty. For example, a filter that matches every rule could be written as ":::=/", or, in short, ":". A filter that matches all the login classes would be "loginclass:". A filter that matches all defined rules for .Sy maxproc resource would be "::maxproc". .Sh SUBJECTS .Bl -column -offset 3n "pseudoterminals" ".Sy username or numerical User ID" .It Em subject Ta Em subject-id .It Sy process Ta numerical Process ID .It Sy user Ta user name or numerical User ID .It Sy loginclass Ta login class from .Xr login.conf 5 .It Sy jail Ta jail name .El .Sh RESOURCES .Bl -column -offset 3n "pseudoterminals" .It Em resource .It Sy cputime Ta "CPU time, in seconds" .It Sy datasize Ta "data size, in bytes" .It Sy stacksize Ta "stack size, in bytes" .It Sy coredumpsize Ta "core dump size, in bytes" .It Sy memoryuse Ta "resident set size, in bytes" .It Sy memorylocked Ta "locked memory, in bytes" .It Sy maxproc Ta "number of processes" .It Sy openfiles Ta "file descriptor table size" .It Sy vmemoryuse Ta "address space limit, in bytes" .It Sy pseudoterminals Ta "number of PTYs" .It Sy swapuse Ta "swap usage, in bytes" .It Sy nthr Ta "number of threads" .It Sy msgqqueued Ta "number of queued SysV messages" .It Sy msgqsize Ta "SysV message queue size, in bytes" .It Sy nmsgq Ta "number of SysV message queues" .It Sy nsem Ta "number of SysV semaphores" .It Sy nsemop Ta "number of SysV semaphores modified in a single semop(2) call" .It Sy nshm Ta "number of SysV shared memory segments" .It Sy shmsize Ta "SysV shared memory size, in bytes" .It Sy wallclock Ta "wallclock time, in seconds" .It Sy pcpu Ta "%CPU, in percents of a single CPU core" .El .Sh ACTIONS .Bl -column -offset 3n "pseudoterminals" .It Em action .It Sy deny Ta deny the allocation; not supported for .Sy cputime and .Sy wallclock .It Sy log Ta "log a warning to the console" .It Sy devctl Ta "send notification to" .Xr devd 8 using .Sy system = "RCTL", .Sy subsystem = "rule", .Sy type = "matched" .It sig* e.g. .Sy sigterm ; send a signal to the offending process.
