On latency in event processing network

Packing, on my way to a family vacation in Anatalya, Turkey.

Following an interesting discussion yesterday about performance metrics -- it turns out that definition of latency in event processing network is quite tricky. The reason is that an event can move in multiple paths over the network, in some it is filterred out, in some it just getting into internal state of agent since it does not complete a pattern, and in some it may complete a pattern and trigger reaction, thus there are various ways to define the metrics here. This is important since optimization has to take into account the goal function - what is being optimized. More discussion on this area -- after I'll return. I'll be out of touch for a week.

VACATION(1)						      General Commands Manual						       VACATION(1)

NAME

       vacation - return ``I am on vacation'' indication

SYNOPSIS

       vacation -I
       vacation user

DESCRIPTION

       Vacation returns a message to the sender of a message telling that you are on vacation.	The intended use is in a .forward file.  For exam-
       ple, your .forward file might have:

	    eric, "|vacation eric"

       which would send messages to you (assuming your login name was eric) and send a message back to the sender.

       Vacation expects a file .vacation.msg in your home directory containing a message to be sent back to each sender.  It should be	an  entire
       message (including headers).  For example, it might say:

	    From: eric@ucbmonet.Berkeley.EDU (Eric Allman)
	    Subject: I am on vacation
	    Delivered-By-The-Graces-Of: the Vacation program

	    I am on vacation until July 22.  If you have something urgent,
	    please contact Joe Kalash <kalash@ucbingres.Berkeley.EDU>.
		 --eric

       This  message  will  only  be  sent  once a week to each unique sender.	The people who have sent you messages are kept in the files .vaca-
       tion.pag and .vacation.dir in your home directory.  The -I option initializes these files, and should be executed before  you  modify  your
       .forward file.

       If  the	-I  flag  is  not specified, vacation reads the first line from the standard input for a UNIX-style ``From'' line to determine the
       sender.	If this is not present, a nasty diagnostic is produced.  Sendmail(8) includes the ``From'' line automatically.

       No message is sent if the initial ``From'' line includes the string ``-REQUEST@'' or if a ``Precedence: bulk'' or ``Precedence: junk'' line
       is included in the header.
