Zabbix 监控Redis

1、python支持

yum -y install python-simplejson

 

2、discovery脚本

[root@localhost etc]# cat  redis_port.py

#!/usr/bin/env python
import os
#import json
import simplejson as json #特别要注意的地方
t=os.popen("""sudo netstat -tlpn |grep codis-server|grep 0.0.0.0|awk '{print $4}'|awk -F: '{print $2}' """)
ports = []
for port in t.readlines():
r = os.path.basename(port.strip())
ports += [{'{#REDISPORT}':r}]
print json.dumps({'data':ports},sort_keys=True,indent=4,separators=(',',':'))

3、试执行脚本

[root@localhost etc]# python redis_port.py

{
    "data":[
        {
            "{#REDISPORT}":"6379"
        }
    ]
}

4、zabbix_agent设置

[root@localhost ~]# tail -n 2 /usr/local/zabbix/etc/zabbix_agentd.conf

UserParameter=redis.discovery,/usr/local/zabbix/etc/redis_port.py

UserParameter=redis_stats[*],redis-cli -h 127.0.0.1 -a redis_passwd -p $1 info|grep $2|cut -d : -f2

[root@localhost ~]# chmod a+x /usr/local/zabbix/etc/redis_port.py 

 

5、sudo权限

[root@localhost ~]# tail -n 1 /etc/sudoers

zabbix ALL=(root) NOPASSWD:/bin/netstat

[root@localhost ~]# sed -i 's/^Defaults.*.requiretty/#Defaults    requiretty/' /etc/sudoers

[root@localhost ~]# grep requiretty /etc/sudoers

#Defaults    requiretty

# changed in order to be able to use sudo without a tty. See requiretty above.

 

6、服务端验证

[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k redis.discovery

{
    "data":[
        {
            "{#REDISPORT}":"6379"
        }
    ]
}

[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k redis_stats[6379,used_memory:]

651534360

[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k "redis_stats[6379,blocked_clients]"

7、zabbix web界面导入下载的模板，添加监控项后检查监控图像
