Hello Harishbabu,

It seems to be a problem sending the script to the host, have you
checked that your oneadmin user belongs to sudoer group?

If that is correct, edit the file $ONE_LOCATION/lib/im_probes/xen.rb
and on line '50' check that appears:

  when 'free_memory'

not

  when 'max_free_memory'


cheers!
