#后来在大神的指导下， Invaild 就是说有格式错误。 OK就是好的，2个里面有一个有了问题。
#再次检查自己的脚本

  1. "counterTpye": "GAUGE",    #  Tpye 是什么，额，，，， 改成Type。

再次查看日志

再次请教大神
看了下各方面日志

Time:1540885244 Time一直都是这个数值，什么鬼，
Time应该是随时间变化的。
重写代码

  1. #!/usr/bin/python
  2. #!-*- coding:utf8 -*-
  3. import requests
  4. import time
  5. import json
  6. ###之前时间在这里，不随函数改变，是个定值，所以dashboard看不到。
  7. def kk():
  8.     ts = int(time.time())   #把这一句移动进去。 这样时间就变化了
  9.     payload = [
  10.         {   
  11.             "endpoint": "test-endpoint-dm",
  12.             "metric": "cam.interfram_avg",
  13.             "timestamp": ts,
  14.             "step": 60, 
  15.             "value": 336,                                    
  16.             "counterType": "GAUGE", 
  17.             "tags": "cluster=detection-machine",
  18.         },
  19.     ]
  20.     r = requests.post("http://127.0.0.1:1988/v1/push", data=json.dumps(payload))
  21.     print(r.text)
  22. while True:
  23.     kk()
  24.     time.sleep(1)

脚本有问题啊， 还是要老实写脚本。

错误3

配置了告警，
open-falcon遇到错误1 - 图1
#接着设置触发， 故意弄个触发值
#但是， 没出现告警
open-falcon遇到错误1 - 图2
#很郁闷， 很受挫，怎么破？
#不着急，着急不解决问题
#让我们来看下架构， 整理下思路
open-falcon遇到错误1 - 图3
1 确保数据从agent上传成功
2确保 transfer传数据到了judge
3确保judge传数据到了redis
4确保alarm收到了redis的数据
##以上 1234基本就是我排查的数据，从下至上， 你也可以从上至下，4321
##查看日志，终于在 alarm.err上看到了报错，（这个日志，默认是/alarm/log/alarm.log）
##6379 redis的端口，大家都知道，问题就出在这
open-falcon遇到错误1 - 图4
##接下来，就是排错了，为什么连不上
1网络
2域名，地址
3权限
4防火墙
……..
#修改好之后， 查看dashboard，可以了。
