Retrieves system information (OS version, available memory, etc.) from a listening Ganglia Monitoring Daemon or Ganglia Meta Daemon.
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:
Set the number of bytes to retrieve. The default value is 1000000. This should be enough for a grid of more than 100 hosts. About 5KB-10KB of data is returned for each host in the cluster.
Set the timeout in seconds. The default value is 60. This should be enough for a grid of more than 100 hosts at 200Kb/s. About 5KB-10KB of data is returned for each host in the cluster.
nmap --script ganglia-info --script-args ganglia-info.timeout=60,ganglia-info.bytes=1000000 -p <port> <target>
