  The EVM daemon configuration file, evmdaemon.conf, is	a text file that con-
  tains	commands used to configure and start the Event Manager.	Any portion
  of a line from an unquoted number sign (#) to	the end	of line	is a comment.
  Blank	lines are ignored.  The	following commands are recognized:

  sourcedir directory
      Names the	directory that should be searched for event template files.
      The default is /usr/share/evm/templates.

  authtimeout time_seconds
      Time to wait for a newly established client to respond to	an authenti-
      cation request.  The default is 10 seconds.

  synctimeout time_seconds
      Time within which	a synchronized client must achieve synchronization
      completing a connection request and subscribing for events. The default
      is 30 seconds.

  portnum port_number
      The port number for TCP communication with remote	clients.  If not
      specified, the evm port number found in /etc/services is used if
      present;	otherwise the reserved default value of	619 is used.

  start_sync command
      The complete command line	for programs that should be started as syn-
      chronized	clients	when the daemon	starts.	This command should be
      enclosed in double quotation marks (").

  remote_connection bool_par
      Determines the permission	for connections	through	a remote TCP port. If
      bool_par evaluates to TRUE, remote connection is permitted.  The
      default is not permitted.	 The bool_par parameter	should be True or


	 Only enable remote access if your system is running in	a fully
	 secure	environment.  See the System Administration guide for event
	 management security considerations.

      A	parameter group	that controls a	daemon event monitoring	facility. An
      activity_monitor definition consists of:

      name detector
	  The type of detector controlled by the group parameters.

      period detect_period
	  The size, in minutes,	of a periodically sliding time window over
	  which	events will be counted.

      threshold	detect_thold
	  The number of	events that will activate the monitor if counted in

      holdoff detect_delay
	  The time delay, in minutes, after activation of the activity moni-
	  tor occurs before monitoring is resumed.  The	evmreload command
	  will reset the delay.

      Defines services that are	available through the daemon.  A service
      definition consists of the name of the service and the command line
      that will	be invoked when	this service is	requested.  User-defined ser-
      vices are	not currently supported.

      A	service	definition consists of:

      name service_name
	  The name given to the	service.

      command service_command
	  The command to be invoked when this service is requested.  This
	  command should be enclosed in	double quotation marks (").

  The keywords described may be	entered	in a case-insensitive manner.  The
  allowable strings and	the minimum number of characters is shown in the fol-
  lowing table.	 A minimum of zero (0) indicates that all characters are

  Keyword	      Minimum
  activity_monitor    0
  authtimeout	      8
  command	      4
  filterdir	      7
  holdoff	      0
  name		      0
  period	      0
  portnum	      4
  remote_connection   0
  service	      7
  sourcedir	      7
  start_sync	      0
  synctimeout	      8
  threshold	      0

  The activity monitor detectors recognized, and the action taken when the
  monitor is activated are the following:

  Detector	Action

		post an	event to alert the system


  This is an example of	an EVM daemon configuration file that does the fol-

   1.  Specifies that event templates are found	in the directory

   2.  Starts the EVM Logger and the EVM Channel Manager as synchronized
       clients when the	daemon is started.

   3.  Defines a service available through the EVM daemon.

   4.  Establishes an activity monitor that will alert the system administra-
       tor if 500 events occur in any 10 minute	span.  Once the	system
       administrator has been alerted, the activity monitor will remain	dor-
       mant for	four hours.

   5.  Disables	connections from remote	hosts.

       # Event template	directory:
       sourcedir       "/usr/share/evm/templates"

       # Start the EVM Logger as a synchronized	client:
       start_sync      "/usr/sbin/evmlogger \
			       -o /var/run/evmlogger.info \
			       -l /var/evm/adm/logfiles/evmlogger.log"

       # Start the EVM Channel Manager as a synchronized client:
       start_sync      "/usr/sbin/evmchmgr \
			       -l /var/evm/adm/logfiles/evmchmgr.log"

       # Event retrieval service definition:
       service	       { name	       event_get
			 command       "/usr/sbin/evmget_srv"

       # Set up	an activity monitor.
       activity_monitor	{
	       name	   event_count	# currently the	only supported monitor
	       period	   10		# count	over a 10 minute period
	       threshold   500		# perform action after 500 events
	       holdoff	   240		# wait 4 hours before resuming

       # Disable remote	communication (set following to	"true" to enable)
       remote_connection       false
