I'm curious. Is installing ganglia part of a class assignment? Does everyone in your class install it or are certain people assigned different tasks? > I have tried > to install the toolkit following, step by step, the documentation, but > there has been this problem: > > Cannot continue because of these errors: > > Invalid element in GANGLIA_DOC XML > > How can I resolve this problem? You are installing an old version of the client v1.0.3 (I think). Version 1.0.4 does not have that problem. You can download it from... http://ganglia.sourceforge.net/ Let me know if the update does not solve your problem (but I'm pretty certain that it will). > I have installed gmond on the server and relative clients, and Ganglia > PHP/RRD Web Client only on the server.

Yes, you need to install gmond on every node on your cluster including the web server. NOTE: If you don't want the web server machine to show up in the list of machines then start gmond with the "--mute" flag. This will make the gmond on the web server listen and process traffic without multicasting it's information. > 2.

The ganglia PHP/RRD Web client only needs to be installed on your web server and no where else. > Have you got a more detailed documentation? Could you send me it? All the documentation for ganglia is at http://ganglia.sourceforge.net/docs/ Good luck! -matt
