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).
|-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.|
