We run ganglia on a 35 node cluster (plus a few odds and ends). It seems pretty lightweight. I've just finished installing the latest versions at home on old slow 32-bit kit and it seems again to be very lightweight. You will need to install libconfuse and RRD though, the former comes as a tarball. You'll need to configure/make/make install and then tell yum to ignore the missing dependency.

Does anyone know any lightweight openosurce soft to do this?? you already have some great answers, but I want to throw in another susggestio : ganglia. Its provided in rpm form at EPEL ( including ganglia-web ), and if you have a trusted network, and multicast is considered ok - you wont need to do any config beyond install, and make 2 config changes in the main /etc/ganglia/gmond.conf file on each of the nodes -- Karanbir Singh, The CentOS Project +44-207-0999389 | http://www.centos.org/ | twitter.com/CentOS GnuPG Key : http://www.karan.org/publickey.asc _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos This email and any attachments to it may be confidential and are intended solely for the use of the individual to whom it is addressed.
