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. |
