#### 6.1 主动模式 ####

[zabbix][] agent检测分为主动（agent active）和被动（agent）两种形式，主动与被动的说法均是相对于agent来讨论的。简单说明一下主动与被动的区别如下：

主动：agent请求server获取主动的监控项列表，并主动将监控项内需要检测的数据提交给server/proxy

被动：server向agent请求获取监控项的数据，agent返回数据。

zabbix agent通信过程中的协议均基于json格式，格式如下：

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div> 
     <div>
       1 
     </div> 
     <div>
       2 
     </div> 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <span>-<span> <span>"ZBXD\x01"<span> <span>(<span>5<span> <span>bytes<span>)</span></span></span></span></span></span></span></span></span> 
     </div> 
     <div> 
      <span> <span>-<span> <span>data <span>length<span> <span>(<span>8<span> <span>bytes<span>)<span>.<span> <span>1<span> <span>will <span>be <span>formatted <span>as<span> <span>01<span>/<span>00<span>/<span>00<span>/<span>00<span>/<span>00<span>/<span>00<span>/<span>00<span>/<span>00<span> <span>(<span>eight <span>bytes <span>in<span> <span>HEX<span>,<span> <span>64<span> <span>bit <span>number<span>)</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

备注：为了避免内存耗尽，server限制每个通信连接最多使用128MB内存。

### 被动检测 ###

server发起如下请求

Aegent返回如下响应数据

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div> 
     <div>
       1 
     </div> 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <span>&lt;<span>HEADER<span>&gt;<span>&lt;<span>DATALEN<span>&gt;<span>&lt;<span>DATA<span>&gt;<span>[<span>\<span>0<span>&lt;<span>ERROR<span>&gt;<span>]</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

**supported items通信过程**

*  Server打开一个TCP连接
 *  Server发送请求agent.ping\\n
 *  Agent接收到请求并且响应<HEADER><DATALEN>1
 *  Server处理接收到的数据1
 *  关闭TCP连接

**not supported items通信过程**

*  Server打开一个TCP连接
 *  Server发送请求vfs.fs.size\[/nono\]\\n
 *  Agent接收请求并且返回响应数据 <HEADER><DATALEN>ZBX\_NOTSUPPORTED\\0Cannot obtain filesystem information: \[2\] No such file or directory
 *  Server接收并处理数据, 将item的状态改为“ not supported ”
 *  关闭TCP连接

### 主动检测 ###

如前面所说，zabbix首先向ServerActive配置的IP请求获取active items，获取并提交active tiems数据值server或者proxy。很多同学会提出疑问：zabbix多久获取一次active items？它会根据配置文件中的RefreshActiveChecks的频率进行，如果获取失败，那么将会在60秒之后重试

备注：获取到的items列表中的所有item属性key, delay, lastlogsize ,mtime都必须存在，获取列表的通信过程如下：

*  Agent打开TCP连接（主动检测变成Agent打开）
 *  Agent请求items检测列表
 *  Server返回items列表
 *  Agent 处理响应
 *  关闭TCP连接
 *  Agent开始收集数据

### 提交active items数据 ###

备注：如果有些数据提交失败，比如host、item被删除或者禁用，agent不会尝试从新提交

主动检测提交数据过程如下：

*   *  Agent建立TCP连接
     *  Agent提交items列表收集的数据
     *  Server处理数据，并返回响应状态
     *  关闭TCP连接

ServerActive 为主动模式 ，agent请求server获取主动的监控项列表，并主动将监控项内需要检测的数据提交给server/proxy

**(1) 主动模式应用场景**  
当我们的zabbix监控平台监控服务器过多，监控项过多的情况下，管理平台会出现以下情况：  
1、管理页面打开缓慢、卡顿，数据加载超时、出现502的情况  
2、开启的进程（Pollar）太多，即使减少item数量，以后加入一定量的机器也会有问题  
解决办法：  
1、增加Proxy节点做分布式监控   
2、调整Agentd为主动模式

**(2)工作原理**  
Agent向Server建立一个TCP连接  
Agent请求需要检测的数据列表  
Server响应Agent，发送一个Items列表  
Agent允许响应  
TCP连接完成本次会话关闭  
Agent开始周期性地收集数据

**(3) 主动模式配置**

LogFile=/var/log/zabbix/zabbix_agentd.log StartAgents=0 开启主动模式 ServerActive=10.10.10.10 HostnameItem=system.hostname

#### 6.2 被动模式 ####

Server为被动模式，server向agent请求获取监控项的数据，agent返回数据。  
**(1)工作原理**  
被动模式工作流程:  
Server 打开一个TCP连接  
Server发送一个key 为agent.ping  
Agent接受这个请求，然后响应<HEADER><DATALEN>1  
Server对接受到的数据进行处理  
TCP连接关闭

(2)配置方法

LogFile=/var/log/zabbix/zabbix_agentd.log Server=10.10.10.10 HostnameItem=system.hostname

### 7、修改配置文件 ###

`shell>vim /usr/local/zabbix_agentd/etc/zabbix_agentd.conf`  
1、根据需求选择主动被动，  
2、因为zabbix监控模板默认使用的就是被动模式，所以zabbix-server端直接添加hosts默认使用的就是被动模式。

### 8、启动zabbix\_agentd 服务 ###

shell>/etc/init.d/zabbix_agentd start 被动模式验证： shell> netstat -tunlp | grep zabbix tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN 30131/zabbix_agentd 主动模式验证： shell>ps -ef | grep zabbix 表明安装成功

### 9、如果需要使用主动模式，且需要使用模版的 ###

1、 配置--模板--Template OS Linux，选择Template OS Linux 全克隆  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent]  
2、重命名新克隆的模版为Template OS Linux\_active  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 1]

3、配置--模版--Template OS Linux\_active--链接的模版--取消Template App Zabbix Agent链接--更新  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 2]

4、配置--模版--Template OS Linux\_active--监控项--全选监控项--批量更新   
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 3]  
监控项目为主动监控项  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 4]

5、配置--主机--创建主机 --链接的模版--选择Template OS Linux\_active--添加--更新  
注意：主机名与配置文件Hostname=test一致  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 5]

![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 6]  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 7]

6、主动模式添加完成后ZBX不显示绿色灯，检测中--最新数据--可以查看到数据即可  
![Linux安装Zabbix Agent（主动模式、被动模式）][Linux_Zabbix Agent 8]  
添加完成后，发现绿色灯不亮是正常的，只要监控有数据就行。
