[Ganglia-general] ganglia problem
My ganglia worked very well until last weekend. After I rebooted computer, I even cannot started internet. Using command /etc/rc.d/init.d/httpd start looks ok but etc/rc.d/init.d/httpd status showed httpd dead but subsys locked and /var/log/httpd/error_log shows that Address already in use: make_sock: could not bind to port 80. I have 2 NICs and that may caused the problem but I don't how to solved the problem. Thanks.
[Ganglia-general] Ganglia Problem
Dear Sir, I'm Florindo D'Onofrio. I'm a student of Computer Science of the Benevento's Unisannio University (Italy). I have found your e-mail in the Ganglia Cluster Toolkit v2.1.2, Monitoring Core Documentation. My teacher has fixed me the task to install ganglia on a cluster, which composed by 8 computers connected to a central computer. 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? I have installed gmond on the server and relative clients, and Ganglia PHP/RRD Web Client only on the server. The installation of the toolkit ganglia is explained in the second section of the documentation: in particular Ganglia Monitoring Daemon (gmond) Installation in the section 2.1 and Installation of the Ganglia PHP/RRD Web Client in the section 2.2. In regard to this I want to ask you 2 questions: 1. Does gmond have to be installed on a server and on each node in the cluster? 2. Does Ganglia PHP/RRD Web Client have to be installed on a server and on each node in the cluster? Have you got a more detailed documentation? Could you send me it? I hope you answer me, thanks.

Today, D'Onofrio Florindo wrote forth saying... Dear Sir, I'm Florindo D'Onofrio. I'm a student of Computer Science of the Benevento's Unisannio University (Italy). I have found your e-mail in the Ganglia Cluster Toolkit v2.1.2, Monitoring Core Documentation. My teacher has fixed me the task to install ganglia on a cluster, which composed by 8 computers connected to a central computer. 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. The installation of the toolkit ganglia is explained in the second section of the documentation: in particular Ganglia Monitoring Daemon (gmond) Installation in the section 2.1 and Installation of the Ganglia PHP/RRD Web Client in the section 2.2. In regard to this I want to ask you 2 questions: 1. Does gmond have to be installed on a server and on each node in the cluster? 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. Does Ganglia PHP/RRD Web Client have to be installed on a server and on each node in the cluster? 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
