zabbix监控之redis自动发现并监控

部分资料来源于网上，这里一并谢过。

系统版本centos5.10

python版本2.4.3 

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]"
0

7，zabbix web界面导入下载的模板，添加监控项后检查监控图像
