Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. The information retrieved includes HDD size, available memory, OS version, architecture (and more) from each of the systems in each of the clusters in the grid. For more information about Ganglia, see: * http://ganglia.sourceforge.net/ * http://en.wikipedia.org/wiki/Ganglia_(software)#Ganglia_Monitoring_Daemon_.28gmond.29 * http://en.wikipedia.org/wiki/Ganglia_(software)#Ganglia_Meta_Daemon_.28gmetad.29 ]] --- -- @usage -- nmap --script ganglia-info --script-args ganglia-info.timeout=60,ganglia-info.bytes=1000000 -p <port> <target> -- -- @args ganglia-info.timeout -- Set the timeout in seconds.
