sinfod - a monitoring tool for networked computers

       Juergen Rinas <jrinas@gmx.de>

sinfod distributes system information to other sinfods on your local network.

       These Information include the system load, memory utilization and the `TOP-5' processes on every machine.

       It's main advantage is, that these informations are broadcasted using the udp(7) protocol.

       If each node broadcasts it's information in a cooperative manner, the network load is O(N),  where  N  is
       the  number  of  nodes  in  your network.  Other systems to monitor your cluster load (e.g.  rup(1) ) are
       using a polling scheme where every node has to ask every other node for the system information:  In  that
       case the network load is O(N**2).

       The task of sinfod is to broadcast the relevant information for the local node and to collect  broadcasts
       from  other  nodes.   Other  programs ( sinfo(1) ) can get access to this information via a simple tcp(7)
       connection that normally is routed through the local loopback interface.

-F/--foreground
              Unlike normal operation, sinfod will not detach from the terminal when given  this  option.   Some
              debugging informations will be visible.

       -q/--quiet
              Start quietly - for init scripts.

       -V/--version
              Print the version number and exit.

       -b#.#.#.#/--bcastaddress=#.#.#.#
              Set  the  broadcast address of the sinfod.  Default is 255.255.255.255.  In you want to run sinfod
              without a network card "-b 127.0.0.1" may be necessary.

       -c/--cmdline
              Broadcast the full command line of a process instead of the command only.

       -mmarker/--marker=marker
              Mark the machine with a name. e.g. laboratory, pool or cluster.

       -i/--ignore<process>
              Don't broadcast any information on <process> ; --ignore may be set multiple times.

       -t/--top<count>
              Broadcast information on the top <count> processes; default: 5

       -ncard/--networkcard=card
              Set the name of the network card whose informations will be broadcasted. (e.g. eth0).  Default  is
              the network card that saw the most traffic at the start of sinfod.

       -Nnicevalue/--nice=nicevalue
              Set the priority of this demon to nicevalue. Default is 15.

       -s/--spymode
              Deactivate  the  TCP  interface  and  the  collection  of received packets.  The demon starts in a
              broadcast-only mode.

       -W/--watchdog
              Start with simple watchdog.
