NAME

6       sinfod - a monitoring tool for networked computers
7

SYNOPSIS

9       sinfod  [-F]  [-q] [-V] [-b #.#.#.#] [-c] [-n card ] [ -N nicevalue ] [
10       -m marker ] [ -i processname ] [-s][-W]
11

DESCRIPTION

13       sinfod distributes system information to other sinfods  on  your  local
14       network.
15
16       These  Information  include the system load, memory utilization and the
17       `TOP-5' processes on every machine.
18
19       It's main advantage is, that these informations are  broadcasted  using
20       the udp(7) protocol.
21
22       If  each  node broadcasts it's information in a cooperative manner, the
23       network load is O(N), where N is the number of nodes in  your  network.
24       Other  systems to monitor your cluster load (e.g.  rup(1) ) are using a
25       polling scheme where every node has to ask every  other  node  for  the
26       system information: In that case the network load is O(N**2).
27
28       The  task  of  sinfod  is to broadcast the relevant information for the
29       local node and to collect  broadcasts from other nodes.  Other programs
30       (  sinfo(1)  )  can  get access to this information via a simple tcp(7)
31       connection that normally is routed through the  local  loopback  inter‐
32       face.

OPTIONS

36       -F/--foreground
37              Unlike  normal operation, sinfod will not detach from the termi‐
38              nal when given this option.  Some debugging informations will be
39              visible.
40
41       -q/--quiet
42              Start quietly - for init scripts.
43
44       -V/--version
45              Print the version number and exit.
46
47       -b #.#.#.#/--bcastaddress=#.#.#.#
48              Set   the   broadcast   address   of  the  sinfod.   Default  is
49              255.255.255.255.  In you want to run sinfod  without  a  network
50              card "-b 127.0.0.1" may be necessary.
51
52       -c/--cmdline
53              Broadcast the full command line of a process instead of the com‐
54              mand only.
55
56       -m marker/--marker=marker
57              Mark the machine with a name. e.g. laboratory, pool or cluster.
58
59       -i/--ignore <process>
60              Don't broadcast any information on <process> ; --ignore  may  be
61              set multiple times.
62
63       -t/--top <count>
64              Broadcast information on the top <count> processes; default: 5
65
66       -n card/--networkcard=card
67              Set  the  name  of  the  network card whose informations will be
68              broadcasted. (e.g. eth0).  Default is the network card that  saw
69              the most traffic at the start of sinfod.
70
71       -N nicevalue/--nice=nicevalue
72              Set the priority of this demon to nicevalue. Default is 15.
73
74       -s/--spymode
75              Deactivate  the  TCP  interface  and  the collection of received
76              packets.  The demon starts in a broadcast-only mode.
77
78       -W/--watchdog
79              Start with simple watchdog.
