NAME
       evmd - Event Manager daemon

SYNOPSIS

DESCRIPTION
       The  Event  Manager  (EVM) daemon, receives events from posting clients
       and distributes them to subscribing clients that	 have  indicated  that
       they  are interested in receiving the events.  The daemon is a critical
       system facility that is started automatically when the  system  transi‐
       tions  to  run level 2, and which should not be terminated.  The daemon
       in turn starts the event logger, and the channel manager,

       On startup, the daemon reads its configuration file, the	 authorization
       file,  and  the	event  template	 files stored under the directory.  If
       these files are modified while the daemon is running, the command  must
       be  used or a signal must be sent to instruct the daemon to reconfigure
       itself.

       The system administrator can control access to events by modifying  the
       EVM authorization file,

       As  a  daemon, does not have a standard output.	Any error messages are
       written to the file

       The EVM daemon is monitored by the Essential Services  Monitor  daemon,
       which  automatically  restarts  if  it  terminates  unexpectedly.   See
       esmd(1M) for more information.

RETURN VALUES
       The following exit values are returned:

       Successful completion.
       An error occurred.

WARNINGS
       The daemon rejects any attempt by a posting client  to  post  an	 event
       that has one or more of the following problems:

       ·  The event is not registered.

       ·  The event contains invalid item values.

       ·  The posting client is not authorized to post such an event.
