       sinfod - a monitoring tool for networked computers


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


       sinfod distributes system information to other sinfods  on  your  local

       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


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

              Start quietly - for init scripts.

              Print the version number and exit.

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

       -m marker/--marker=marker
              Set  mark  the  machine  with  a  name. e.g. laboratory, pool or

       -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.

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

              Start with simple watchdog.
