zabbix3.4监控redis

1.1 导入模板

附件如下:


1.2 创建采集脚本

我的监控采集脚本都放到了/etc/zabbix/scripts/,在这里创建脚本保存shell脚本:

[root@redis-01 ~]# cat /etc/zabbix/scripts/redis.sh

#!/bin/bash

赋予权限:chmod +x redis.sh

 

1.3 编辑agentd配置文件

cd /etc/zabbix/zabbix_agentd.d/

[root@redis-01 ~]# cat /etc/zabbix/zabbix_agentd.conf.d/redis.conf

#监控redis状态,我们可以根据这个参数对应的监控项创建redis状态触发器。

UserParameter=redis.status,/home/deploy/redis/bin/redis-cli -a "Creadit2018Admin" -h 127.0.0.1 -p 6379 ping |grep -c PONG 

#item参数如何get

UserParameter=redis_info[*],/etc/zabbix/scripts/redis.sh $1 $2

 

1.4 重启agentd服务,使之生效。

systemctl restart zabbix-agent.service

然后到zabbixweb界面,配置、主机、点击主机名称,然后点击模板,在文本框中输入redd,自动搜索出reddis的模板,点击选择,点击添加,点击更新。

然后到zabbixweb界面,管理,一般,其他,修改此项设置:

刷新不支持的监控项目(,默认600秒,我改成60

此时再去查看该主机的最新数据,就可以看到监控信息了:

 

如果看到有些图形里面的单位不对,则

 

1.5  Zabbix获取的数值自定义单位

# find / -name "func.inc.php"

/home/deploy/nginx/html/zabbix/include/func.inc.php

# Vim /home/deploy/nginx/html/zabbix/include/func.inc.php

$blackList = [%msrpmRPM];

改为$blackList = [%msrpmRPM‘个‘];

 

修改zabbix页面监控项

模板--监控项--添加-单位--个

即可
