Script Description

The ganglia-info.nse script 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:

Ganglia-info NSE Script Arguments

This is a full list of arguments supported by the ganglia-info.nse script:

ganglia-info.bytes

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.

ganglia-info.timeout

Set the timeout in seconds. The default value is 30.

slaxml.debug

Debug level at which default callbacks will print detailed parsing info. Default: 3

- - -
To use these script arguments, add them to the Nmap command line using the --script-args arg1=value,[arg2=value,..] syntax. For example:

nmap --script=ganglia-info --script-args ganglia-info.bytes=value,ganglia-info.timeout=value <target>

Ganglia-info NSE Script Example Usage

Here's an example of how to use the ganglia-info.nse script:

nmap --script ganglia-info --script-args ganglia-info.timeout=60,ganglia-info.bytes=1000000 -p <port> <target>
