> Refine system metric schema design and fix system metric collector
> h1. Principle
> Any metric (no mater jmx/sys metric) should at least have three fields:
> "metric", "group", "timestamp", "value",
> "group" is the metric category path separated with slash, for example "FIRST
> CATEGORY/SECOND CATEGORY", which will be commonly used for well organizing
> metric groups in customized metric dashboard.
> h1. Stream Schema for System metric
>
> * *metric*: [STRING] metric name string
> * *group*: [STRING] metric group/type
> * *timestamp*: [LONG] metric generation time
> * *site*: [STRING] siteId
> * *host*: [STRING] source host name
> * *device*: [STRING] device name, like cpu
> h1. Sample CPU Metric
> {code}
> {
> "timestamp": 1487918913569,
> "metric": "system.cpu.usage",
> "group": "System/CPU",
> "site": "sandbox",
> "value": 0.058,
> "host": "sandbox.hortonworks.com",
> "device": "cpu7"
> }
> {code}
> h1. Sample Network Metrics
> {code}
> {
> "timestamp": 1487918913569,
> "metric": "system.nic.transmitdrop",
> "group": "System/Network",
> "site": "sandbox",
> "value": 7724.0,
> "host": "sandbox.hortonworks.com",
> "device": "eth0"
> }
> {code}
> Hadoop Namenode Metric
> {code}
> {
> "timestamp": 1487918913569,
> "metric": "hadoop.namenode.capacity",
> "group": "Hadoop/Namenode",
> "site": "sandbox",
> "value": 7724.0,
