# 主机Meta数据

## 简介

`metric_meta_host` `input`插件用于采集主机的Meta信息（例如CPU型号、内存大小、进程等）。

## 配置参数

| 参数                   | 类型       | 是否必选 | 说明                                             |

| Type                 | String   | 是    | 插件类型                                           |
| CPU                  | Boolean  | 否    | <p>是否开启主机CPU采集。</p><p>默认取值：是。</p>              |
| Memory               | Boolean  | 否    | <p>是否开启主机Memory采集。</p><p>默认取值：是。</p>           |
| Net                  | Boolean  | 否    | <p>是否开启主机Net采集。</p><p>默认取值：否。</p>              |
| Disk                 | Boolean  | 否    | <p>是否开启主机Disk采集。</p><p>默认取值：否。</p>             |
| Process              | Boolean  | 否    | <p>是否开启主机Process采集。</p><p>默认取值：否。</p><p>件。</p> |
| ProcessNamesRegex    | String数组 | 否    | 进程名过滤规则，支持正则匹配。件。                              |
| Labels               | String字典 | 否    | 自定义Labels。件。                                   |

## 样例

采集主机上CPU、Memory、Net、Disk、Process等Meta信息。

#### 采集配置

```
enable: true
inputs:
  - Type: metric_meta_host
    CPU: true
    Memory: true
    Net: true
    Disk: true
    Process: true
    ProcessIntervalRound: 60
    ProcessNamesRegex:
      - ilogtail
    Labels:
      cluster: ilogtail-test-cluster
flushers:
  - Type: flusher_sls
    Endpoint: cn-hangzhou.log.aliyuncs.com
    ProjectName: test-ilogtail-xxx
    LogstoreName: metric-meta
```

#### 输出

* 主机Meta信息
