evmd(8)
NAME
  evmd - Event Manager daemon

SYNOPSIS
  /usr/sbin/evmd

OPTIONS
  None

OPERANDS
  None

DESCRIPTION
  The EVM daemon, evmd, receives events from posting clients and distributes
  them to subscribing clients that have indicated that they are interested in
  receiving them. The daemon is a critical system facility that is started
  automatically when the system transitions to level 2, and which should not
  be terminated.  The daemon in turn starts the logger, evmlogger, and the
  channel manager, evmchmgr.

  On startup, the daemon reads its configuration file, /etc/evmdaemon.conf,
  the authorization file, /etc/evm.auth, and the event template files stored
  under the /usr/share/evm/templates directory.	 If these files are modified
  while the daemon is running, the evmreload -d(8) command must be used to
  instruct the daemon to reconfigure itself.

  The system administrator can control access to events at any level by
  modifying the EVM authorization file, /etc/evm.auth.

  As a daemon, evmd does not have a standard output. Any error messages are
  written to the file /var/evm/adm/logfiles/evmdaemon.log.

  The daemon reconfigures itself when evmreload -d is run, or upon receipt of
  a SIGHUP signal.

RESTRICTIONS
  The daemon rejects any attempt by a posting client to post an event that is
  not registered, that contains invalid item values, or that the poster is
  not authorized to post.

EXIT VALUES
  The following exit values are returned:

  0   Successful completion

  non 0
      An error occurred
