I think it crashes out parsing json from /_node/stats

The os key from _node/stats looks like this

os: {

        free_percent: 37,
        used_percent: 63
    },
    swap: {

    }
}

Looks like load_average is being reported as a single number, rather than an array of 1m, 5m, 15m values.

I'm also not seeing a key "merge" key in thread_pool

Had this issue here aswell, with 2.x (specifically, 2.1)
