because you want a percent, you'll have to either tell argus how big your 
disk is or else you can tell it to ask the server how big the disk is.

asking the server how big the disk is seems silly, as argus will have to 
keep asking and the answer will rarely change.

this should work - but not tested:

Group "machine" {
  hostname: machine.example.com
  Service UDP/SNMP {
    # data for behind the scenes
    hidden: yes
    oid: .1.3.6.1.2.1.25.2.3.1.6.2
    uname: disk_used_c
  }
  Service Compute {
    # n.b. the 10000000000, below, is total disk size in bytes
    expr: ( %{Top:Servers:machine:disk_used_c} / 10000000000 ) * 100
    gr_range: 0-100
    ylabel: percent used
    graph: yes
    label: disk usage on C:
    uname: disk_usage_c
    maxvalue: 90
    messagedn: disk usage percent at %v on %o{ip::hostname} C:
    messageup: disk usage better on %o{ip::hostname} C:
  }
}
