Some of the operations currently supported by the GENIDesktop CLI Tool are :

  • Check status of the slice/slivers
  • Download files from nodes in the Slice
  • Download passive monitoring data collected from nodes in a CSV, PNG and RRD formats.
  • Download a list of slice, list of nodes/link from a slice or the whole slice topology itself in a JSON format.
  • Run commands on the node(s) in the slice. (Similar to the Run module in the GUI)
  • Upload file(s) to the node(s) in the slice. (Similar to the File upload module in the GUI)
  • CLI version of the Experiment validation tool provided in the GUI.
