Installation The 3dmon-package contains a server (the mosstatd daemon) which has to be installed on one node which belongs to your openMosix cluster. It will be started automatically by a xinetd-service or has to be started manually by its init-script as a standalone server process. The 3d-view "3dmosmon" connects to that server and gets the data for the 3d-display. You can run 3dmosmon (the 3d-view) also on a non-openMosix node (from outside your cluster) The 3dmosmon binary needs therefor the servername as a commandline-parameter e.g. 3dmosmon [servers_hostname] Anyways the automatic setup-procedure will install both (mosstatd + 3dmosmon) on the system and you could simply execute: 3dmosmon localhost after successfull installation. (both binaries will be installed in /usr/bin) Using mosstatd with xinetd If you system is using xinetd you need to configure the following xinetd-service by creating the file /etc/xinetd.d/mosstatd with the following content: service mosstatd { socket_type = stream wait = no user = nobody log_on_success += USERID log_on_failure += USERID server = /usr/bin/mosstatd } It will be automatically performed when you choose to use xinetd during the installation. Using mosstatd with inetd If you system is using inetd you need the following line in your /etc/inetd.conf -file for providing the mosstatd-service to the 3dmosmon GUI. # mosstatd service for 3dmon mosstatd    stream  tcp  nowait  root  /usr/bin/mosstatd It will be automatically performed when you choose to use inetd during the installation. using mosstatd as a stand-alone server If you are neither using xinetd nor inetd you can also choose to install the mosstatd-daemon as a standalone server (during installation). Then the installation will create an init-script for the mosstatd-server. You can easy start/stop it with: /etc/init.d/mosstatd [start/stop/status] You can also link it to runlevel e.g. 3 or 5 to start it permanently during boot-up of the system. /etc/services entry for the mosstatd server For using the 3dmosmon your system needs to know on which TCP-port the mosstatd-daemon is running. For that reason there is an entry in the /etc/services -file required. This following line will be automatic added to your /etc/services if you use the automatic installation by the setup-script or the RPM-installation. mosstatd     10050/tcp     #openMosix/Mosix stat daemon To install from the source-tarball: -download 3dmon.tar.gz and unzip/untar it in /usr/local -cd into the 3dmon directory -execute ./setup PRM-installation: -download the 3dmon.rpm -execute rpm -ihv 3dmon.rpm How to use it Set your DISPLAY variable correct and execute: 3dmosmon localhost You should now see a nice 3d-view. The right-mouse button which will "enter the flying" mode. You can now move around by pressing the control keys: w for up s for down a for left d for right or your mouse buttons: left button move on middle button move back right button toggle "flying"-mode (centers the view and spin it) By default 3dmosmon display the load of the nodes in your cluster. pressing 'm' shows a memory-overview pressing 'u' shows a util-overview pressing 'l' shows the load-view again have fun + fly into your openMosix cluster
