返回当前内存中的metrics信息

/metrics/list 例如: http://localhost:8006/metrics/list:

{
  data: {
    jvm: [
      {
        interval: 15,
        metric: "jvm.buffer_pool.direct.capacity",
        metricLevel: "NORMAL",
        metricType: "GAUGE",
        tags: {}
      },
      {
        interval: 15,
        metric: "jvm.buffer_pool.direct.count",
        metricLevel: "NORMAL",
        metricType: "GAUGE",
        tags: {}
      }
      ...
    ],
    system: [
      {
        interval: 5,
        metric: "system.context_switches",
        metricLevel: "MAJOR",
        metricType: "GAUGE",
        tags: {}
      },
      {
        interval: 5,

        metricLevel: "MAJOR",
        metricType: "GAUGE",
        tags: {}
      }
      ...
    ],
    nginx: [
      {
        interval: 5,
        metric: "middleware.nginx.conn.accepted",
        metricLevel: "MAJOR",
        metricType: "GAUGE",
        tags: {}
      },
      {
        interval: 5,
        metric: "middleware.nginx.conn.active",
        metricLevel: "MAJOR",
        metricType: "GAUGE",
        tags: {}
      }
      ...
    ],
    tomcat: [
      {
        interval: 15,
        metric: "middleware.tomcat.thread.busy_count",
        metricLevel: "NORMAL",
        metricType: "GAUGE",
        tags: {}
      },
      {
        interval: 15,

        metricLevel: "NORMAL",
        metricType: "GAUGE",
        tags: {}
      }
    ]
  },
  success: true,
  message: "",
  timestamp: 1548057052707
}

返回某个group下的所有metrics指标

/metrics/$group

例如: http://localhost:8006/metrics/jvm:

{
  data: [
    {
      interval: 15,
      metric: "jvm.buffer_pool.direct.capacity",
      metricLevel: "NORMAL",
      metricType: "GAUGE",
      tags: { },
      timestamp: 1548057958220,
      value: 32768
    },
    {
      interval: 15,
      metric: "jvm.buffer_pool.direct.count",
      metricLevel: "NORMAL",
      metricType: "GAUGE",
      tags: { },
      timestamp: 1548057958220,
      value: 4
    }
    ...
  ],
  success: true,
  message: "",
  timestamp: 1548057958228
}

返回某一个group下指定的metrics

/metrics/$group/$metricName

例如: http://localhost:8006/metrics/jvm/jvm.buffer_pool.direct.count

{
  data: [
    {
      interval: 15,
      metric: "jvm.buffer_pool.direct.count",
      metricLevel: "NORMAL",
      metricType: "GAUGE",
      tags: { },
      timestamp: 1548058350794,
      value: 5
    }
  ],
  success: true,
  message: "",
  timestamp: 1548058350795
}

访问某一个group下指定的metrics， 按照tag进行过滤

http://$IP:8006/metrics/$group/$metricName?tagKey=$tagKey&tagValue=$tagValue

如果多个tag可以指定多个tagKey和tagValue

访问某个具体的级别的指标

http://$IP:8006/metrics/$group/level/$level

访问某个级别以上的指标

http://$IP:8006/metrics/$group/level/$level？above=true

一次获取多个group的指标

http://$IP:8006/metrics/$group[，$group]*

一次获取多个group的指标, 不同group指定不同级别

http://$IP:8006/metrics/$group[，$group]*/level/$level[,$level]*

指定获取一个或多个metrics指标（metrics 1.0.5版本以上支持）

GET方式

http://$IP:8006/metrics/specific?metric=$metricName[&metric=$metricName]*

POST方式

将metric=$metric&metric=$metric放在POST BODY里面。

过滤掉统计值为0的统计项

GET方式：http://$IP:8006/metrics/specific?metric=$metricName&zeroIgnore=true

POST方式：将zeroIgnore=true放在POST BODY里面。

zeroIgnore默认为false，当需要过滤掉统计值为0的统计项，需要置成true
