how would you feel about making these field names consistent with the monitoring format? i could see us eventually consolidating these.

As quickly discussed, this is based on the metricbeat naming conventions: https://www.elastic.co/guide/en/beats/libbeat/5.1/event-conventions.html

Metric beat is collecting os level stats, we were going to remove kbnServer.stats.memory. Since this isn't general enough to also handle monitorings use we should remove from the kbnServer object.

For Cloud, we probably don't want to display system load and memory. |

I updated the PR and put an example event in the PR description. |
This adds an api page under `/api/_node` which provides the basic status information about the running Kibana node.
**Example Event**
An event exposed by the `/api/_node` looks as following:
```
{
"name":"ruflin",
"version":"6.0.0-alpha1",
"build":{
"num":8467,
"sha":"6cb7fec4e154faa0a4a3fee4b33dfef91b9870d9"
},
"uuid":"5b2de169-2785-441b-ae8c-186a1936b17d",
"heap":{
"total":125079552,
"used":87140680,
"rss":150970368
},
"connections":0,
"requests":{
"total":2,

}
}
```

@ruflin, I did some digging today. It appears there is already an API endpoint for the status page.
And the response for that page: {
"name":"tsmalley",

"buildSha":"6cb7fec4e154faa0a4a3fee4b33dfef91b9870d9",

}The last ~12 metrics are provided with the timestamp for when they were taken. You can either take the latest or average them out, which is what the status page does. Thoughts on simply using this? |

I'm aware of this api endpoint and it's not fetcher friendly, especially because of the array nature. That is the reason I introduced the new API endpoint. |
