Zabbix3.4監控Redis

一. 環境

Centos 7.2
Zabbix 3.4
Redis 5.0.0

二 zabbix-agent配置

1. 編輯zabbix-agent的zabbix_agentd.conf

vim /etc/zabbix/zabbix_agentd.conf

添加:

UserParameter=Redis.Info[*],/etc/zabbix/script/redis/redismonitor.sh 2>/dev/null  $1 $2
# 通過腳本監控信息 
UserParameter=Redis.Status,(/datastore/redis/redis-5.0.0/src/redis-cli -h 192.168.126.128 -p 6379 -a 密碼  ping)2>/dev/null | grep -c PONG

使用錯誤重定向（2>/dev/null）是防止報錯導致監控項失效無法告警，具體錯誤爲 : 538840574" of type “string” is not suitable for value type "Numeric (unsign)"

設置AllowRoot=1，目的是以root用戶去執行腳本

2. 添加腳本

新建redismonitor.sh，放在/etc/zabbix/script/redis目錄下，當然這個目錄你可以隨便改
腳本內容爲：

#! /bin/bash
#Name: redismontior.sh
#From: liuhaibin 2018.5.29
#Action: Zabbix monitoring redis plug-in
#根據自己的安裝情況填寫命令位置主機ip和端口

zabbix監控redis只要是通過“info”查看信息， 如果redis沒有密碼的話，記得把$Pass去掉
修改腳本的可執行權限

chmod +x redismonitor.sh

重啓 agent

service zabbix-agent restart

3. 導入模板

在zabbix web端導入web模板 [鏈接：https://pan.baidu.com/s/1NjGyxqJcy4YmMBDZUcJGRg
提取碼：sktv ]

三 測試

在zabbix 服務端用zabbix_get命令測試是否配置成功

zabbix_get -s 192.168.126.128 -k Redis.Info[used_memory]
