Zabbix 分佈式zabbix-proxy主動模式

 

zabbix proxy代理概述

---

zabbix proxy 可以代替 zabbix server 收集性能和可用性數據,然後把數據彙報給 zabbix server,並且在一定程度上分擔了zabbix server 的壓力.

此外，當所有agents和proxies報告給一個Zabbix server並且所有數據都集中收集時，使用proxy是實現集中式和分佈式監控的最簡單方法。

zabbix proxy 使用場景:

• 監控遠程區域設備

• 監控本地網絡不穩定區域

• 當 zabbix 監控上千設備時,使用它來減輕 server 的壓力

• 簡化分佈式監控的維護

當 zabbix 監控上千設備時,使用它來減輕 server 的壓力
簡化分佈式監控的維護
注意：zabbix_proxy的數據庫必須與zabbix_server的數據庫分開。不過可以同時在server端創建zabbix數據庫與zabbix_proxy數據庫，記得授權即可。 

 

 實戰部署

實驗環境:
監控端：192.168.179.102
代理端：192.168.179.103
被監控端：192.168.179.104

 

代理端：192.168.179.103 zbbix proxy安裝與配置

---

這裏使用yum安裝，在192.168.179.103執行下列命令 

安裝proxy和連接mysql數據庫的組件
[root@localhost ~]# yum install zabbix40-proxy.noarch   zabbix40-proxy-mysql.x86_64  zabbix40-dbfiles-mysql.noarch -y

因爲zabbix proxy是會收集agent的數據，所以也需要數據庫 

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

 創建數據庫，導入表結構，對於Zabbix proxy 數據庫, 只需要導入 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                    |

| 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爲主動， 1爲被動
Hostname=proxy-123      #代理服務器名稱，需要與zabbix server添加代理時候的proxy name是一致的！
Server=192.168.179.102  #zabbix server服務器的地址或主機名 
DBHost=localhost        #數據庫服務器地址
DBUser=zabbix
HeartbeatFrequency=60   #心跳間隔檢測時間，默認60秒，範圍0-3600秒， 被動模式不使用
ConfigFrequency=60      #間隔多久從zabbix server 獲取監控信息
DataSenderFrequency=3   #數據發送時間間隔，默認爲1秒，範圍爲1-3600秒，被動模式不使用
ProxyLocalBuffer=3      #數據同步到server，數據還會保存多久，單位小時
ProxyOfflineBuffer=24   #未提交的數據保存多長時間

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

 

被監控端：192.168.179.104 zabbix agent安裝與配置

---

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

[root@localhost ~]# vim /etc/zabbix_agentd.conf 
Server=192.168.179.103 #這裏填寫proxy的地址，因爲是由proxy來收集數據的 

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

 

接下來就可以在zabbix server的web端設置了 添加代理

---

 這個名字要和配置文件裏面Hostname=proxy-123保持一致,而且默認是主動模式

接下來添加主機，由proxy收集數據 

 

 查看proxy是否配置成功
