NAME
       sys_attrs_psm - psm subsystem attributes

DESCRIPTION
       This  reference page lists and describes attributes for the Process Set
       Manager (psm) kernel subsystem, which monitors the state of vital  pro‐
       cesses.	The  application  interfaces  to  the  psm  subsystem  are the
       cfg_psm_catops() and cfg_psm_memops() routines in the  libcfg  library.
       These  routines	create	the process categories and members used by the
       psm  software.  Refer  to  cfg_psm_catops(3),  cfg_psm_memops(3),   and
       libcfg(3) for more information.

       Refer  to  the  sys_attrs(5)  reference page for an introduction to the
       topic of kernel subsystem attributes.

       An asterisk (*) preceding the name of an	 attribute  in	the  following
       list  means that the attribute can be configured at run time. Values of
       other attributes cannot be changed without rebooting the system.

	      The maximum number of process categories.

	      Default: 512 (categories)

	      Minimum: 0

	      Maximum: 18,446,744,073,709,551,615

	      Once the psm_cat_max value is reached, an attempt to  create  an
	      additional  category  results  in the [ENOSPC] error. Categories
	      cannot be deleted; so, an attempt to delete a category after  it
	      is  created  results  in	the  [ENOTSUP]	error.	Therefore, the
	      psm_cat_max value must be increased if the program  will	create
	      more than 512 categories.

	      A	 set  of  bit  flags,  defined	in the psm.h header file, that
	      enable various debugging messages.

	      Default: 0 (all debugging messages disabled)

	      A value that determines whether new process categories are auto‐
	      matically	 created  (1)  or  not created (0) at the time process
	      members are instantiated.

	      Default: 1 (new categories are automatically created)

	      A specific process instance can be registered in only one	 cate‐
	      gory.   An  attempt to register a currently running process in a
	      category where it is already registered  results	in  the	 [EAL‐
	      READY] error. The default setting simplifies the boot process.

	      The maximum number of process members that can be registered for
	      all process categories.

	      Default: 1024 (members)

	      Minimum: 0

	      Maximum: 18,446,744,073,709,551,615

	      Once the psm_mem_max value is reached, an attempt to register an
	      additional member results in the [ENOSPC] error.

	      The maximum number of process members that can be registered per
	      process category.

	      Default: 64 (members)

	      Minimum: 0

	      Maximum: 18,446,744,073,709,551,615

	      Once the psm_memcat_max value is	reached	 for  a	 category,  an
	      attempt  to  register another member in that category results in
	      the [ENOSPC] error.

	      A set of bit flags, defined in the psm.h header file, that  dis‐
	      ables the posting of selected events.

	      Default: 0 (all events are posted)
