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  tran-
       sitions 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 reconfig-
       ure 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:
