+
+OBAgent 是一个监控采集框架。OBAgent 支持推、拉两种数据采集模式，可以满足不同的应用场景。OBAgent 默认支持的插件包括主机数据采集、OceanBase 数据库指标的采集、监控数据标签处理和 Prometheus 协议的 HTTP 服务。要使 OBAgent 支持其他数据源的采集，或者自定义数据的处理流程，您只需要开发对应的插件即可。
+
+## 特性
+
+OBAgent 具有以下特性：
+
+- 采用 Go 语言开发，无需外部依赖。
+- 插件驱动，易开发。

+# OBAgent 开发指南
+
+OBAgent 是一个插件驱动的监控采集框架。要扩展 OBAgent 的功能，或者自定义数据的处理流程，您可以开发对应的插件。开发插件时，您只需要实现插件的基本接口和对应类型插件的接口即可。
+
+## OBAgent 数据处理流程
+
+![Screenshot 2021-09-15 at 11.36.11.png](https://intranetproxy.alipay.com/skylark/lark/0/2021/png/28412/1631676986085-49f40134-9502-438b-bb32-5a3ee6591fbc.png#clientId=u89a16740-3189-4&from=ui&id=ucf4512dc&margin=%5Bobject%20Object%5D&name=Screenshot%202021-09-15%20at%2011.36.11.png&originHeight=868&originWidth=1638&originalType=binary&ratio=1&size=108483&status=done&style=none&taskId=uc6b3bf07-12ab-4e56-9568-bdab0001cc4)
+
+OBAgent 的数据处理流程包括数据采集、处理和上报，需要用到的插件包含输入插件（Inputs）、处理插件（Process）、输出插件（OutPuts 和 Exporter）。插件详细信息，参考 [外部插件](#外部插件) 章节。
+

+| 处理插件（Process）   | 串行进行数据处理。                                                              |
+| 输出插件（Output）   | 仅适用于推模式。用来将 metrics 数据推送到远端。     |
+输出插件（Exporter） | 仅适用于拉模式。通过 HTTP 服务暴露数据。用来为 metrics 做格式转换。
+
+### 输入插件接口定义
+
+```go
+type Input interface {
+    Collect() ([]metric.Metric, error)
+}
+```
+
+输入插件需要实现 Collect 方法采集数据。输入插件返回一组 metrics 和 error。
+​
+
+### 处理插件接口定义
+
+```go
+type Processor interface {
+    Process(metrics ...metric.Metric) ([]metric.Metric, error)
+}
+```
+
+处理插件需要实现 Process 方法处理数据，输入参数是一组 metrics，输出一组 metrics 和 error。
+​
+
+### 输出插件（Exporter）接口定义
+
+```go
+type Exporter interface {
+    Export(metrics []metric.Metric) (*bytes.Buffer, error)
+}
+```
+
+输出插件（Exporter）需要实现 Export 方法，输入参数是一组 metrcs，输出 byte buffer 和 error。
+
+### 输出插件（Output）接口定义
+
+```go
+type Output interface {
+    Write(metrics []metric.Metric) error
+}
+```
+
+输出插件（Output）需要实现 Write 方法，输入参数是一组 metrics，输出 error。
+
+## Metric 接口定义
+
+OBAgent 数据处理流程中流转的数据定义为统一的 Metric 接口。
+
+```go

+        SetName(name string)
+        GetName() string
+        SetTime(time time.Time)
+        GetTime() time.Time
+        SetMetricType(metricType Type)
+        GetMetricType() Type
+        Fields() map[string]interface{}
+        Tags() map[string]string
+}
+```
+
+## 插件基本接口定义
+
+所有的 OBAgent 插件都必须实现以下的基本接口：
+
+```go
+//Initializer 包含 Init 函数
+type Initializer interface {
+    Init(config map[string]interface{}) error
+}
+
+//Closer 包含 Close 函数
+type Closer interface {
+    Close() error
+}
+
+//Describer 包含 SampleConfig 和 Description

+# 手动部署 OBAgent
+
+OBAgent 提供使用 OBD 部署和手动部署。要手动部署 OBAgent，您要配置 OBAgent、Prometheus 和 Prometheus Alertmanager（可选）。推荐您使用 OBD 部署 OBAgent。
+
+## 前提条件
+
+在部署 OBAgent 之前，您需要确认以下信息：
+
+- OceanBase 数据库服务已经部署并启动。
+- OBAgent 已经安装。详细信息，参考 [安装 OBAgent](install-obagent.md)。
+- OBAgent 的默认端口 8088、8089 未占用。您也可以自定义端口。
+
+## 操作步骤
+
+按以下步骤部署 OBAgent：
+
+### 步骤1：部署 monagent
+
+1. 修改配置文件，详细信息，参考 [monagent 配置](../config-reference/monagent-config.md) 和 [KV 配置](../config-reference/kv-config.md)。
+
+2. 启动 monagent 进程。推荐您使用 Supervisor 启动 monagent 进程。
+
+    ```bash
+    # 将当前目录切换至 OBAgent 的安装目录
+    cd /home/admin/obagent
+    # 启动 monagent 进程
+    nohup ./bin/monagent -c conf/monagent.yaml >> ./log/monagent_stdout.log 2>&1 &
+
+    ```
+
+    ```bash
+    # Supervisor 配置样例
+    [program:monagent]
+    command=./bin/monagent -c conf/monagent.yaml
+    directory=/home/admin/obagent
+    autostart=true
+    autorestart=true
+    redirect_stderr=true
+    priority=10
+    stdout_logfile=log/monagent_stdout.log
+    ```
+
+### （可选）步骤2：部署 Prometheus
+
+> 说明：您需要安装 Prometheus。
+
+1. 配置 Prometheus，详情参考 [Prometheus 配置文件说明](../config-reference/prometheus-config.md)。
+2. 启动 Prometheus。
+
+    ```bash
+    ./prometheus --config.file=./prometheus.yaml
+    ```
+
+### （可选）步骤3：部署 Prometheus Alertmanager
+
+- 下载并解压 Prometheus Alertmanager。
+- 启动 Prometheus Alertmanager。
+- 配置 Prometheus Alertmanager。更多信息，参考 [Prometheus 文档](https://www.prometheus.io/docs/alerting/latest/configuration/)。
+
+OBAgent 提供默认的报警项，配置文件位于 `conf/prometheus_config/rules`。其中，`host_rules.yaml` 存储机器报警项，`ob_rules.yaml` 存储 OceanBase 数据库报警项。如果默认报警项不能满足您的需求，按照以下方式自定义报警项：
+
+```yaml
+#在 Prometheus 的配置文件中增加报警相关的配置。报警相关的配置文件需放在 rules 目录，且命名满足 *rule.yaml。
+
+groups:
+- name: node-alert
+    rules:
+    - alert: disk-full
+    expr: 100 - ((node_filesystem_avail_bytes{mountpoint="/",fstype=~"ext4|xfs"} * 100) / node_filesystem_size_bytes {mountpoint="/",fstype=~"ext4|xfs"}) > 80
+    for: 1m
+    labels:
+        serverity: page
+    annotations:
+        summary: "{{ $labels.instance }} disk full "
+        description: "{{ $labels.instance }} disk > {{ $value }}  "
+```
+
+## （可选）更新 KV 配置
+
+OBAgent 提供了更新配置的接口。您可以通过 HTTP 服务更新 KV 配置项：
+
+```bash
+# 您可以同时更新多个 KV 的配置项，写多组 key 和 value 即可。
+
+curl --user user:pass -H "Content-Type:application/json" -d '{"configs":[{"key":"monagent.pipeline.ob.status", "value":"active"}]}' -L 'http://ip:port/api/v1/module/config/update'
+```

+# 使用 OBD 部署 OBAgent
+
+OBAgent 提供使用 ODB 部署和手动部署。要手动部署 OBAgent，您要配置 OBAgent、Prometheus 和 Prometheus Alertmanager（可选）。推荐您使用 OBD 部署 OBAgent。
+
+## 前提条件
+
+在部署 OBAgent 之前，您需要确认 OBAgent 的默认端口 8088、8089 未占用。您也可以自定义端口。
+
+> **说明**：如果您的机器可以连接公网，在您执行了 `obd cluster deploy` 命令之后，OBD 将检查您的目标机器是否有 OBAgent 安装包。如果没有安装包，OBD 将自动从 yum 源获取。
+
+## 同时部署 OceanBase 集群和 OBAgent
+
+如果您希望同时部署 OceanBase 集群和 OBAgent，您只需要在 OceanBase 数据库的配置文件中添加以下 OBAgent 的配置信息：
+
+```yaml
+obagent:
+  servers:
+    - 127.0.0.1
+  depends: 
+    - oceanbase-ce
+  global:
+    home_path: /root/observer
+```
+
+> **注意**：`servers` 字段必须与 oceanbase-ce 的 `servers` 字段一致。
+
+详细信息，参考 [配置文件](https://github.com/oceanbase/obdeploy/blob/master/example/obagent/distributed-with-obproxy-and-obagent-example.yaml)。
+
+## 单独部署 OBAgent
+
+OBD 不支持为已部署的集群添加新的组件。如果您希望为要已部署的集群配置 OBAgent，您需要单独部署 OBAgent。要单独部署 OBAgent，您需要准备 OBAgent 的配置文件。请确保配置文件中的以下字段与 OceanBase 数据库相同：
+
+```yaml
+obagent:
+  global:
+    # Username for HTTP authentication. The default value is admin.
+    http_basic_auth_user: admin
+    # Password for HTTP authentication. The default value is root.
+    http_basic_auth_password: root
+    # Username for debug service. The default value is admin.
+    pprof_basic_auth_user: admin
+    # Password for debug service. The default value is root.
+    pprof_basic_auth_password: root
+    
+    # 以下配置必须与 OceanBase 数据库一致
+    # Monitor username for OceanBase Database. The user must have read access to OceanBase Database as a system tenant. The default value is root.
+    monitor_user: root
+    # Monitor password for OceanBase Database. The default value is empty. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the root_password in oceanbase-ce.
+    monitor_password: 
+    # The SQL port for observer. The default value is 2881. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the mysql_port in oceanbase-ce.
+    sql_port: 2881
+    # The RPC port for observer. The default value is 2882. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the rpc_port in oceanbase-ce.
+    rpc_port: 2882
+    # Cluster name for OceanBase Database. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the appname in oceanbase-ce.
+    cluster_name: obcluster
+    # Cluster ID for OceanBase Database. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the cluster_id in oceanbase-ce.
+    cluster_id: 1
+    # Zone name for your observer. The default value is zone1. When a depends exists, OBD gets this value from the oceanbase-ce of the depends. The value is the same as the zone name in oceanbase-ce.
+    zone_name: zone1
+    # Monitor status for OceanBase Database.  Active is to enable. Inactive is to disable. The default value is active. When you deploy an cluster automatically, OBD decides whether to enable this parameter based on depends.

+# 安装 OBAgent
+
+您可以使用 RPM 包或者构建源码安装 OBAgent。
+
+## 环境依赖
+
+构建 OBAgent 需要 Go 1.14 版本及以上。
+
+## RPM 包
+
+OBAgent 提供 RPM 包，您可以去 [Release 页面](https://mirrors.aliyun.com/oceanbase/community/stable/el/7/x86_64/obagent-1.0.0-1.el7.x86_64.rpm) 下载 RPM 包，然后使用以下命令安装：
+
+```bash
+rpm -ivh obagent-1.0.0-1.el7.x86_64.rpm
+```
+
+## 构建源码
+
+### Debug 模式
+
+```bash
+make build // make build will be debug mode by default
+make build-debug
+```
+
+### Release 模式
+
+```bash
+make build-release
+```
+
+## OBAgent 安装目录结构
+
+OBAgent 的安装目录包含三个子目录：`bin`、`conf` 和 `run`。OBAgent 的安装目录如下：
+
+```bash
+# 目录结构示例
+.
+├── bin
+│   └── monagent
+├── conf
+│   ├── config_properties
+│   │   ├── monagent_basic_auth.yaml
+│   │   └── monagent_pipeline.yaml
+│   ├── module_config
+│   │   ├── monagent_basic_auth.yaml
+│   │   ├── monagent_config.yaml
+│   │   ├── monitor_node_host.yaml
+│   │   └── monitor_ob.yaml
+│   ├── monagent.yaml
+│   └── prometheus_config
+│       ├── prometheus.yaml
+│       └── rules
+│           ├── host_rules.yaml
+│           └── ob_rules.yaml
+└── run
+```
+
+其中，`bin` 用来存放二进制文件。`conf` 用来存放程序启动配置、模块配置模板、KV 变量配置和 Prometheus 的配置模板。`run` 用来存放运行文件。更多关于配置文件的信息，参考 配置文件参考(LINK TODO)。

-# obagent数据处理流程

-obagent将插件组合，定义成流水线，流水线作为基本的调度单位，实现一个完整的数据采集，处理和上报流程，同时支持两种模式，推模式和拉模式，一个流水线包含一组input插件，并行进行数据采集，一组processor插件，串行进行数据处理，拉模式包括一个exporter插件，通过http服务的方式将数据暴露出来，推模式包括一个output插件，实现数据推送功能,  流水线中流转的数据定义为统一的Metric接口，为了扩展obagent的能力，可以自定义开发一些插件，插件的开发只需要实现插件的基本接口和对应类型插件的接口即可
-​
-
-# metric接口定义
-```go
-type Metric interface {
-        Clone() Metric
-        SetName(name string)
-        GetName() string
-        SetTime(time time.Time)
-        GetTime() time.Time
-        SetMetricType(metricType Type)
-        GetMetricType() Type
-        Fields() map[string]interface{}
-        Tags() map[string]string
-}
-```
-
-
-# 插件基本接口定义
-```go
-//Initializer contains Init function
-type Initializer interface {
-	Init(config map[string]interface{}) error
-}
-
-//Closer contains Close function
-type Closer interface {
-	Close() error
-}
-
-//Describer show SampleConfig and Description
-type Describer interface {
-	SampleConfig() string
-	Description() string
-}
-
-```
-所有obagent的插件都必须实现以上的基本接口
-
-- Init方法用来做插件的初始化工作
-- Close方法在插件退出时调用，用来关闭一些资源
-- SampleConfig方法返回插件的配置样例
-- Description方法返回插件的描述信息
-
-​
-
-# 不同类型插件的接口定义
-## Input插件
-```go
-type Input interface {
-	Collect() ([]metric.Metric, error)
-}
-```
-intput 插件需要实现Collect方法, 来采集数据，返回一组metric和error
-​
-
-## Processor插件
-```go
-type Processor interface {
-    Process(metrics ...metric.Metric) ([]metric.Metric, error)
-}
-```
-processor插件需要实现Process方法，用来做数据处理，输入参数是一组metric，输出一组metric和error
-​
-
-## Exporter插件
-```go
-type Exporter interface {
-	Export(metrics []metric.Metric) (*bytes.Buffer, error)
-}
-```
-exporter插件需要实现Export方法，输入参数是一组metric，输出byte buffer 和 error， 作用是将metric做格式转换，只用在拉模式
-​
-
-## Output插件
-```go
-type Output interface {
-	Write(metrics []metric.Metric) error
-}
-```
-output插件需要实现Write方法，输入参数是一组metric，输出error，作用是将metric数据推送到远端，只用在推模式

-# 安装和配置
-obagent提供rpm包，可以使用rpm命令进行安装
-// TODO: replace with real url
-[obagent-0.1-1.alios7.x86_64.rpm]()
-
-```bash
-rpm -ivh obagent-0.1-1.alios7.x86_64.rpm
-```
-​
-
-**目录结构**
-安装之后会有一个binary文件，和一组配置文件，配置文件中又分为程序启动配置，模块配置模版和kv变量的配置, 另外为了方便使用还有一个prometheus的配置模版
-```bash
-# 目录结构示例

-​
-
-**monagent.yaml配置文件:**
-```bash
-## 日志相关配置
-log:
-  level: debug
-  filename: log/monagent.log
-  maxsize: 30
-  maxage: 7
-  maxbackups: 10
-  localtime: true
-  compress: true
-
-## 进程相关配置，address是默认的拉取metric和管理相关接口，adminAddress是pprof调试端口
-server:
-  address: "0.0.0.0:8088"
-  adminAddress: "0.0.0.0:8089"
-  runDir: run
-
-## 配置相关，加密方法支持aes和plain，如果是aes，会使用下面key文件中的key对需要加密的配置项进行加密
-## modulePath中存放配置模版，propertiesPath存放kv变量配置
-cryptoMethod: plain
-cryptoPath: conf/.config_secret.key
-modulePath: conf/module_config
-propertiesPath: conf/config_properties
-```
-​
-
-**配置模版**
-```bash
-## basic auth 相关配置，可以配置两个端口开启或者关闭，配置disabled后对应的变量 {disable_http_basic_auth} {disable_pprof_basic_auth}
-monagent_basic_auth.yaml 
-
-## 配置模块相关的配置，一般不需要修改
-monagent_config.yaml
-
-## 主机监控流水线配置模版,一般不需要修改
-monitor_node_host.yaml
-
-## OB监控流水线配置模版，一般不需要修改
-monitor_ob.yaml

-
-
-**kv配置项**
-```bash
-## basic auth 相关的kv配置项
-monagent_basic_auth.yaml
-
-## 流水线相关的kv配置项
-monagent_pipeline.yaml
-```
-**​**
-
-**kv配置项说明:**
-```yaml
-# encrypted=true的配置项, 需要加密存储，目前支持aes加密方法，
-# {}中的变量需要进行替换，替换成真实的值，如果monagent启动配置中设置了加密方法=aes, 需要配置加密之后的值
-
-## basic auth

-# 启动命令
-cd /home/admin/obagent
-nohup ./bin/monagent -c conf/monagent.yaml >> ./log/monagent_stdout.log 2>&1 &
-
-# supervisor 配置样例
-[program:monagent]
-command=./bin/monagent -c conf/monagent.yaml
-directory=/home/admin/obagent
-autostart=true
-autorestart=true
-redirect_stderr=true
-priority=10
-stdout_logfile=log/monagent_stdout.log
-```
-**​**
-
-**配置更新:**
-obagent提供了配置更新的接口, 可以通过http服务的方式更新kv配置项，具体的调用方式
-```bash
-# 可以同时更新多个kv的配置项，写多组key和value的值即可
-
-curl --user user:pass -H "Content-Type:application/json" -d '{"configs":[{"key":"monagent.pipeline.ob.status", "value":"active"}]}' -L 'http://ip:port/api/v1/module/config/update'
-```
-# prometheus采集配置
-**prometheus配置样例**
-```yaml
-# obagent的rpm包中携带了一份prometheus的配置模版，可以根据实际情况做一些修改，
-# 如果开启basic auth认证，需要配置{http_basic_auth_user} {http_basic_auth_password}
-# {target} 替换成主机的ip + port
-# rules 目录下有两个报警配置模版，分别是默认的主机和ob报警配置，如需自定义报警项，可以作为参考
