Zabbix监控之Redis自动发现并监控（python）
1、python支持yum -y install python-simplejson
2、discovery脚本
# catredis_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 redis-server|grep 0.0.0.0|awk '{print $4}'|awk -F: '{print $2}' """)
ports = []
for port int.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
# python redis_port.py
{
"data":[
{
"{#REDISPORT}":"6379"
}
]
}
4，zabbix_agent设置
# 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
# chmod a+x /usr/local/zabbix/etc/redis_port.py
5，sudo权限
# tail -n 1 /etc/sudoers
zabbix ALL=(root) NOPASSWD:/bin/netstat
# sed -i 's/^Defaults.*.requiretty/#Defaults requiretty/' /etc/sudoers
# 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
# zabbix_get -s 172.17.2.114 -k redis.discovery
{
"data":[
{
"{#REDISPORT}":"6379"
}
]
}
# zabbix_get -s 172.17.2.114 -k redis_stats
651534360
# zabbix_get -s 172.17.2.114 -k "redis_stats"
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
