使用Zabbix3.4监控工具创建 redis监控模板并实现redis监控

本案例以Zabbix-2.2.2为监控平台进行创建,该方法对于zabbix 2.X以及3.X的方法也是一样可以使用,只不过zabbix 2.x平台导入模板的时候,需要编辑模板xml文件将version 3.0改成2.0才可以导入,否则出错。如zabbix  V3.X,则可以直接导入并按照如下方法配置使用。这里只是一个通用操作,如需更加完善功能可以自己添加监控项以及触发器等。
1,导入模板
下载链接: http://download.21yunwei.com/zabbix/redis/zbx_template_redis.tar.gz  导入模板成功以后,将需要监控redis的主机添加这个模板。
注意:需 确认监控平台版本,低于3.0的需要编辑xml改成2.0后再去导入。

 

2,创建采集脚本
我的监控采集脚本都放到了/home/yunwei/redis_zbx.sh,在这里创建脚本保存shell脚本:
vim redis_zbx.sh

#!/bin/bash
REDISPATH="/usr/bin/redis-cli"
HOST="127.0.0.1"

REDIS_INFO="$REDISPATH -h $HOST -p $PORT info"

赋予权限:chmod +x redis_zbx.sh

3,编辑agentd配置文件

#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。
#redis monitor
UserParameter=redis.status,/usr/bin/redis-cli -h 127.0.0.1 -p 6379 ping |grep -c PONG 
UserParameter=redis_info[*],/home/yunwei/redis_zbx.sh $1 $2 

重启agentd服务,使之生效。

好了,我们到administraton-general-other刷新下被监控主机不支持的监控项,使之生效后测试看下效果(太多数据了,这里只举例几个):
内存使用情况:
使用Zabbix3.4监控工具创建 redis监控模板并实现redis监控 监控工具 第1张

redis status状态信息:
使用Zabbix3.4监控工具创建 redis监控模板并实现redis监控 监控工具 第2张

说明:
1,这个模板redis监控的参数比较多,具体根据自己的实际情况启用redis里边的应用集或者监控项,也可以自己再添加,。
2,默认aof未开启 以及slave这里都有监控,用不到的就停掉,这个模板。当前模板四个触发器,其中关于aof和主从的关了,只保留了redis存活状态和redis磁盘回写失败与否两个触发器。
