sinfod - a monitoring tool for networked computers
sinfod [-F] [-q] [-V] [-b #.#.#.#] [-n card ] [ -N nicevalue ] [ -m
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.
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.
Set mark the machine with a name. e.g. laboratory, pool or
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.
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.
