Mongoose Sub Document Woes

Question

I have sub document as in metrics. But I don\'t think I am saving correctly, because each document doesn\'t have metrics data correctly..instead it shows metrics: [ \'[object Ob

When including a field named type in a sub-doc of a Mongoose schema, you need to define its type using an object or it looks to Mongoose like you're declaring the type of the parent field.

So change your schema to:

var CpuSchema = new Schema({
    timeStamp : { type : Date, index: true },
    avaiable : Boolean,
    status : String,
    metrics : [ { duration : String,
        data : Number,
        type : {type: String},
        unit : String
    } ,
    { duration : String,
        data : Number,
        type : {type: String},
        unit : String
    },
    { duration : String, 
        data : Number,
        type : {type: String},
        unit : String
    }
    ]
});
