I'd index data like:

```auto
PUT index/doc/test01
{
   "Uptime":277887,
   "Name":"test01",
   "TotalOutput":0,
   "TotalOutputRate":0,
   "Cal":{
      "C1":0,
      "S1":0,
      "M1":0,
      "S1":0,
      "R1":0,
      "R2":0
   },
   "TotalConnections":0,
   "TotalInputRate":0,
   "TotalInput":0
}

```

Warning: `S1` is a duplicated key, which is wrong.
