    Statspy is designed to run on:
         Sun-3s and Sun-4s, under Sun OS3.x and Sun OS4.x;
         Vax and MIPS architecture machines under Ultrix;
         IBM PC RTs.

    User Document:
         doc.ms  -- nroff -ms source
         doc.txt -- text
         
    CHANGES -- list of changes
         
    Source files:
         Makefile -- used to build statspy, rspy, collect, and lookupnames
         *.h, *.c -- source
         pfilt.h, pfiltrt.h -- one of these should be useful to RT installation
         
    Example/suggested configuration and parameter files:
         parm.sample* -- suggested configuration files for statspy
         parm.enum, parm.portenum -- 'include' enum files.
         networks.txt -- table used by lookupnames (from standard hosts.txt)

    Scripts and awk files for data reduction:
         count-totals.alias -- script to define count-totals command
         bin-totals.alias -- script to define bin-totals command
         dailytotals.awk,  
         dailytotalsB.awk, 
         newlines.awk,
         subtotals.awk -- AWK scripts used by count-totals, bin-totals
         
To make programs: comment in the appropriate set of Make macros (see
Makefile) and do:

         make all
    
    Note that can generate more efficient version without subnet virtual
    fields, with: make all SUBNET=
    
To run statspy on a SunOs or IBM RT system, you must first become
super-user.  To run statspy on an Ultrix system, you need not be
super-user, but the super-user must first enable the use of promiscuous
mode using /etc/pfconfig (e.g., "/etc/pfconfig +p -a").

To start statspy, execute the shell command:
    
         statspy parm.sample1
         
    Sun OS/4.0.x contained a serious bug in NIT.  If this is not fixed, 
    statspy will fail immediately with an error message: 
        "NNStat: Fatal NIT error
         Statspy depends upon bug fix in nit_if.c"
        
    Fixed modules for Sun3 and Sun4 are available for anonymous FTP from
    host venera.isi.edu with pathnames:
        pub/nit_if.o
        pub/nit_if.o.sparc
        
To see what statspy is collecting, enter the command line:
    
         read *
         
To see the commands, enter 

         ?
    
If you don't want to tie up a window, however, start it as a background
job:
    
         statspy parm.sample1 >& statspy.log &  
   
To start collect, execute the shell command (Superuser not necessary!):

          collect -e enum.NSF -i 5 -c 60 -h <host> '*'
          
Here <host> is domain name or dotted-decimal number of the host on
which statspy is running.  This will poll for data every 5 minutes,
saving checkpoints every 60 minutes, and put the data into a set of
files, one per object.

To run collect in background, putting standard error into a file, use:

           collect -e parm.enum.collect.sample -i 5 -c 60 -h <host> '*' 
                                                            >& error.log &
           
To install the reduction commands, issue:

           source count-totals.alias
           source bin-totals.alias
           
These will issue alias commands to define count-totals and bin-totals for the
current session.  It may be desirable to edit your .login file to include
these alias definitions.

To summarize the Total Count data in all log files whose names include
the string "IP", use: 

           count-totals v=1 *IP*
           
for hourly totals, or for daily totals:

           count-totals  *IP*

To summarize by corresponding bins, use:

           bin-totals *IP*
           
To remotely control statspy, use:

           rspy -h <host> parm.rspy
           
where <host> specifies the network host on which statspy is running.
