利用Zabbix官方模板监控Redis

主机环境:
[root@test ~]# uname -a

Zabbix版本:3.4.9
redis版本:
[root@test ~]# redis-server -v

主机防火墙和selinux关闭
Zabbix yum安装参考:https://www.tracymc.cn/archives/614,编译安装可参考https://www.tracymc.cn/archives/218.
redis安装参考:https://www.tracymc.cn/archives/397
项目地址:https://github.com/blacked/zbx_redis_template

具体步骤:
1.主机环境
[root@test scripts]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 test //这步不能忘,我的redis装在Zabbix server上面,所以这里直接写了127.0.0.1

2.安装python环境
[root@test ~]# yum -y install python-pip
[root@test ~]# pip install argparse
[root@test ~]# pip install redis

3.设置键值
[root@test home]# unzip zbx_redis_template-master.zip

-rwxr-xr-x 1 root root 318 9月 22 2016 zbx_redis.conf //配置文件

-rwxr-xr-x 1 root root 86427 9月 22 2016 zbx_redis_trapper_templates.xml
[root@test zbx_redis_template-master]# cp zbx_redis_stats.py /etc/zabbix/scripts/
根据实际情况修改脚本如下内容:
zabbix_host = '127.0.0.1' # Zabbix Server IP
zabbix_port = 10051 # Zabbix Server Port
hostname = 'test' #redis主机在zabbix web上的名字,要一致,不然可能会报错.
[root@test scripts]# chmod u+x /etc/zabbix/scripts/zbx_redis_stats.py //赋权
-p:redis端口号
-a:redis设置的认证密码,如果没有设置密码就不需要此选项
[root@test ~]# cat /etc/zabbix/zabbix_agentd.conf |grep conf|grep -v ‘#’ //yum安装zabbix的话agent默认配置文件为/etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd.d/*.conf //你懂的,包含/etc/zabbix/zabbix_agentd.d下面的配置
设置键值:
[root@test scripts]# cat /etc/zabbix/zabbix_agentd.d/zbx_redis.conf
UserParameter=redis[*],/etc/zabbix/scripts/zbx_redis_stats.py -a 123456 -p 6379 123456 $1 $2 $3 //最好先-a再-p,不然会报错,当时在这边卡了很久
验证脚本:
[root@test scripts]# /etc/zabbix/scripts/zbx_redis_stats.py -a 123456 -p 6379 test expired_keys none
0
说明键值配置成功.
