       evlfacility  -v|--verify [file]

       The evlfacility command lets  you  list  contents  of  the
       event logging facility registry, replace the entire facil­
       ity registry, add facilities (with options) to the  facil­
       ity  registry,  delete  facilities,  or modify an existing

       For evlfacility options that modify the facility registry,
       event  logging applications already in progress will start
       using the modified registry within 5 seconds. The  follow­
       ing  options  are  accepted  (unless otherwise noted, root
       permission is required to use these options):


       -l, --list
              Displays the facility names and associated  integer
              values   contained   in   the   facility  registry,
              /etc/evlog.d/facility_registry.    Also    displays
              whether  the  facility logs events from the kernel,
              which  events,  if  any,   are   written   to   the
              /etc/evlog.d/privatelog file, and which events have
              restricted logging.

              This option is available to all users.

       -v, --verify [file]
              Checks the  validity  of  the  indicated  file  and
              reports  any  errors found to stderr. If no file is
              specified, then the contents of the  facility  reg­
              istry   file,  /etc/evlog.d/facility_registry,  are
              checked for validity.

              wise, events will be logged from user-space.

              If --private is specified, then events logged  with
              the  specified  facility will be logged to the pri­
              vate log file, /etc/evlog.d/privatelog, instead  of
              the standard log file, /etc/evlog.d/eventlog.

              If  a  filter  is  specified, it indicates that for
              this facility, only records that  match  the  indi­
              cated filter will be logged. Only attributes in the
              fixed-portion of the event record may  be  used  in
              the  filter expression.  See the  evlquery man page
              for more information.

       -F, --force
              Valid only with --add.  Ordinarily, an  attempt  to
              add  a  facility  that  is  already in the registry
              results in a diagnostic message and a non-zero exit
              status.  If --force is specified, and the specified
              facility is already in  the  registry,  evlfacility
              just  verifies that the existing entry has the cor­
              rect (automatically assigned) code for that  facil­
              ity  name;  --kernel,  --private,  and --filter are

       -d, --delete facility-name
              Deletes an entry from the facility registry for the
              specified facility-name.

       -c,  --change  facility-name [-k|--kernel] | [-u|--user] |
       [-p|--private]  |  [-n|--noprivate]  |  [-f|--filter  fil­
              Modifies  one  or  more  of the optional parameters
              associated with facility-name in the facility  reg­

              -k, --kernel
                     Adds  the  "kernel" parameter for the speci­
                     fied facility-name in the facility registry.
                     This option is not valid with --user.

              -u, --user
                     Removes the "kernel" parameter for the spec­
                     ified facility-name  in  the  facility  reg­
                     istry.  This option is not valid with --ker­

              -p, --private
                     Adds the "private" parameter for the  speci­
                     fied facility-name in the facility registry.
                     This option is not valid with --noprivate.


       evlfacility --add "Mr Admin" --private
       --filter 'log_format!=BINARY && gid="admins"'

       Adds the facility "Mr Admin"  to  the  facility  registry.
       Events  from  this  facility will be logged to the private
       log. BINARY events will  not  be  logged  (only  variable-
       length  data formats of NODATA or STRING), and events will
       be logged only if group id is "admins".
