Zabbix 自动发现Redis并监控

yum -y install python-simplejson    #安装python 支持

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=(',',':'))

chmod +x redis-port.py
python redis-port.py               # 下面执行结果

{
    "data":[
        {
            "{#REDISPORT}":"6379"
        },
        {
            "{#REDISPORT}":"6380"
        }
    ]
}

vim /etc/zabbix/zabbix_agentd.conf  #添加下面两行

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

grep requiretty /etc/sudoers   #显示如下
