       evmd - Event Manager daemon




       The  Event  Manager  (EVM)  daemon,  evmd, 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 crit‐
       ical system facility that is  started  automatically  when  the	system
       transitions  to	run  level  2, and which should not be terminated. The
       daemon in turn starts the event logger, evmlogger, and the channel man‐
       ager, evmchmgr.

       On  startup,  the  daemon  reads	 its  configuration file, /etc/evmdae‐
       mon.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  com‐
       mand  must be used or a SIGHUP signal must be sent to instruct the dae‐
       mon to reconfigure itself.

       The system administrator can control access to events 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 EVM daemon is monitored by the Essential Services  Monitor  daemon,
       esmd,  which automatically restarts evmd if it terminates unexpectedly.
       See esmd(8) for more information.

       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.

       The following exit values  are  returned:  Successful  completion.   An
       error occurred.

       Executable  file	 Default  directory for event template files.  Default
       location for event filter files. Filter	files  must  have  the	suffix
       Error log file for evmd.	 UNIX domain socket established for connection
       between the EVM daemon and the local clients.  Daemon process id	 saved
       by  evmd.  Lock file established to prevent multiple invocations of the
       daemon.	 Default  location  of	the  EVM  daemon  configuration	 file.
       Default location of the EVM daemon authorization file.
