Useful Commands

  • The following command uses gstat to get a list of nodes by load. It then sorts the list by load/free CPUs and connects you to the node with the most free CPUs. The format below is an alias that you can put in your .bashrc file if you want it to be automatically applied to your environment.
 alias fss='ssh `/opt/ganglia/bin/gstat -p8651 -1a -i necluster | grep node | sort -gr -k 2 | sort -k 7 | head -n1 | cut -f1 -d" "`'


  • Get cluster load information from Ganglia in a terminal:
 /opt/ganglia/bin/gstat -p8649 -1a -i necluster
