zabbix proxy代理概述

zabbix proxy 可以代替 zabbix server 收集性能和可用性数据,然后把数据汇报给 zabbix server,并且在一定程度上分担了zabbix server 的压力.

此外，当所有agents和proxies报告给一个Zabbix server并且所有数据都集中收集时，使用proxy是实现集中式和分布式监控的最简单方法。

zabbix proxy 使用场景:

  • 监控远程区域设备
  • 监控本地网络不稳定区域
  • 当 zabbix 监控上千设备时,使用它来减轻 server 的压力
  • 简化分布式监控的维护

集中收集时，使用proxy是实现集中式和分布式监控的最简单方法。

 

应用场景

监控远程区域设备
监控本地网络不稳定区域
当 zabbix 监控上千设备时,使用它来减轻 server 的压力
简化分布式监控的维护
注意：zabbix_proxy的数据库必须与zabbix_server的数据库分开。不过可以同时在server端创建zabbix数据库与zabbix_proxy数据库，记得授权即可。

 实战部署

实验环境:
监控端：192.168.179.102
代理端：192.168.179.103
被监控端：192.168.179.104

 

代理端：192.168.179.103 zbbix proxy安装与配置

这里使用yum安装，在192.168.179.103执行下列命令 

安装proxy和连接mysql数据库的组件
[root@localhost ~]# yum install zabbix40-proxy.noarch   zabbix40-proxy-mysql.x86_64  zabbix40-dbfiles-mysql.noarch -y

因为zabbix proxy是会收集agent的数据，所以也需要数据库 

[root@localhost ~]# yum install mariadb mariadb-server mariadb-devel -y
[root@localhost ~]# systemctl start  mariadb

 创建数据库，导入表结构，对于Zabbix proxy 数据库, 只需要导入 schema.sql (不需要 images.sql 和 data.sql)

MariaDB [(none)]> create database zabbix_proxy charset utf8;
MariaDB [(none)]> grant all on zabbix_proxy.* to "zabbix"@localhost identified by "123456";
MariaDB [(none)]> flush privileges;

[root@localhost ~]# mysql -uzabbix -p123456 zabbix_proxy < /usr/share/zabbix-mysql/schema.sql 
MariaDB [(none)]> use zabbix_proxy;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [zabbix_proxy]> show tables;
+----------------------------+
| Tables_in_zabbix_proxy     |
+----------------------------+
| acknowledges               |
| actions                    |
| alerts                     |
| application_discovery      |
| application_prototype      |
| application_template       |
| applications               |

修改配置文件/etc/zabbix_proxy.conf

[root@localhost ~]# vim /etc/zabbix_proxy.conf 
############ GENERAL PARAMETERS #################

### Option: ProxyMode
#       Proxy operating mode.
#       0 - proxy in the active mode
#       1 - proxy in the passive mode
#
# Mandatory: no
# Default:
# ProxyMode=0

ProxyMode=0             #0为主动， 1为被动
Hostname=proxy-123      #代理服务器名称，需要与zabbix server添加代理时候的proxy name是一致的！
Server=192.168.179.102  #zabbix server服务器的地址或主机名 
DBHost=localhost        #数据库服务器地址
DBUser=zabbix
HeartbeatFrequency=60   #心跳间隔检测时间，默认60秒，范围0-3600秒， 被动模式不使用
ConfigFrequency=60      #间隔多久从zabbix server 获取监控信息
DataSenderFrequency=3   #数据发送时间间隔，默认为1秒，范围为1-3600秒，被动模式不使用
ProxyLocalBuffer=3      #数据同步到server，数据还会保存多久，单位小时
ProxyOfflineBuffer=24   #未提交的数据保存多长时间

[root@localhost ~]# systemctl start zabbix-proxy

 

被监控端：192.168.179.104 zabbix agent安装与配置

[root@localhost ~]# yum install zabbix40-agent.x86_64  -y

[root@localhost ~]# vim /etc/zabbix_agentd.conf 
Server=192.168.179.103 #这里填写proxy的地址，因为是由proxy来收集数据的 

[root@localhost ~]# systemctl start zabbix-agent

 

接下来就可以在zabbix server的web端设置了 添加代理

 这个名字要和配置文件里面Hostname=proxy-123保持一致,而且默认是主动模式

接下来添加主机，由proxy收集数据
