NAME

       sinfod - a monitoring tool for networked computers

SYNOPSIS

       sinfod  [-F]  [-q]  [-V]  [-b #.#.#.#] [-c] [-n card ] [ -N nicevalue ] [ -m marker ] [ -i
       processname ] [-s][-W]

DESCRIPTION

       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.

OPTIONS

       -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.

       -m marker/--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

       -n card/--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.

       -N nicevalue/--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.
