Attention! I apologize, but it is automatic machine translation of the text. You can improve it if will send to me more correct version of the text or fix html pages via GITHUB repository. Commands:% cbsd jrctl % cbsd jrctl-tuiDescription: To view the statistics, set and unset limits on the jail, use the command cbsd jrctl. This command with the keys: % cbsd jrctl mode=apply ... % cbsd jrctl mode=unset ...automatically called for the install or removal of limits when working jstart or jstop respectively. By command % cbsd jrctl mode=showyou can see current statistics on the jail resources consumed, which can be used to generate reports and graphs for loading jail, as well as the cbsd daemon used to generate recommendations on the need to add new resources and for overload warnings. By jrctl you can set the following limits jail: a) All you can do a framework FreeBSD rctl(8): cputime CPU time, in seconds datasize data size, in bytes stacksize stack size, in bytes coredumpsize core dump size, in bytes memoryuse resident set size, in bytes memorylocked locked memory, in bytes maxproc number of processes openfiles file descriptor table size vmemoryuse address space limit, in bytes pseudoterminals number of PTYs swapuse swap usage, in bytes nthr number of threads msgqqueued number of queued SysV messages msgqsize SysV message queue 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 memory segments shmsize SysV shared memory size, in bytes wallclock wallclock time, in seconds b) Set the priority level of one over the other jail renice(8), for example, you may want to give for jail with distcc lowest priority, while the jail with HTTP server - the middle priority, and the jail with the database - is high priority. c) In the case of file system ZFS, set a quota on the use of the file system. %
