Zabbix监控Redis性能状态-工具盒子

Zabbix监控Redis性能状态

监控原理示意图：

监控原理

Zabbix-server通过agent监控中配置文件调用shell脚本。Redis中提供redis-cli 命令使用info可以获得redis大部分信息。在使用shell命令获取到需要的信息。

监控操作步骤：

1、编辑脚本

2、上传脚本到指定位置

3、修改zabbix_agent配置文件

4、zabbix_server的web界面导入模版（编辑模板）

5、主机关联

1、配置zabbix_agent配置文件，添加以下内容

[root@localhost ~]# vim /usr/local/zabbix/etc/zabbix_agentd.conf

UserParameter=Redis.Info[*],/data/scripts/auto_detection_redis_state.sh $1

#保存退出

2、重启Zabbix_agentd服务

[root@localhost ~]# service zabbix_agentd restart

3、下载脚本文件（获取监控值）

[root@localhost ~]# cd /data/scripts

[root@localhost scripts]# wget -c https://mirrors.yangxingzhen.com/shell/auto_detection_redis_state.sh

[root@localhost scripts]# cat auto_detection_redis_state.sh

#脚本内容如下

#!/bin/bash

4、脚本授权

[root@localhost scripts]# chmod +x auto_detection_redis_state.sh

5、验证server端验证是否能获取agent端的key值

#使用zabbix_get命令获取key值
