[系统运维]open-falcon自定义监控设置方法

1、使用shell脚本获取结果值： 0或1

vim /data/python/monitor-port.sh
#!/bin/bash
#监控端口
INPUT=$1
VALUE=`/usr/bin/netstat -ntl | grep ${INPUT} |awk '{print $4}' | awk -F: '{print $2}' | grep "^${INPUT}$"`
if [ $? -eq 0 ];then
	echo "1"
else
	echo "0"
fi

2、使用Python脚本push数据，添加到计划任务中执行

!/use/bin/env python
# -*- coding:utf8 -*-

import requests
import time
import json
import commands

val = commands.getoutput('bash /data/python/monitor-port.sh 9667')
ts = int(time.time())
payload = [
    {
        "endpoint": "node1",
        "metric": "wf-sms-callback-port",
        "timestamp": ts,
        "step": 60,
        "value": val,
        "counterType": "GAUGE",
    },

]

r = requests.post("http://127.0.0.1:1988/v1/push", data=json.dumps(payload))
print r.text

3、添加计划任务：

*/1 * * * * /usr/bin/python /data/python/push.py

4、添加报警
