sinfod - a monitoring tool for networked computers
sinfod [-F] [-q] [-V] [-b #.#.#.#] [-c] [-n card
] [ -N nicevalue ] [ -m marker ] [ -i
processname ] [-s][-W]
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.
- -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.
