Sensu Handler没有触发

似乎我的新Sensu Handler没有被调用。 但首先,我的配置。 在/etc/sensu/conf.d/checks.json中:

{
"checks":
   "custom_check":{
      "command": "python3.6 /srv/custom_check.py",
      "subscribers": ["remote-checks"],
      "interval": 600,
      "ttl": 900,
      "handlers": ["custom_handler"],
      "source":"my-check-target"
   }
}
/etc/sensu/conf.d/handlers.json中的

{
  "handlers": {
    "custom_handler": {
      "type": "pipe",
      "command": "python3.6 /srv/custom-sensu-handlers/handler.py"
}

在服务器日志中,我看到:

 {
  "timestamp":"2018-04-25T07:51:47.253449+0200",
  "level":"info",
  "message":"publishing check request",
  "payload":{"command":"python3.6 /srv/custom_checks/custom_check.py",
  "ttl":900,
  "handlers":["custom_handler"],
  "source":"my-check-target",
  "name":"custom_check",
  "issued":1524635507},
  "subscribers":["remote-checks"]
}

客户端日志:

{
  "timestamp": "2018-04-30T06:24:00.012625+0200",
  "level": "info",
  "message": "received check request",
  "check": {
    "command": "python3.6 /srv/custom_checks/custom_check.py",
    "ttl": 900,
    "handlers": [
      "default",
      "custom_handler"
    ],
    "source": "my_check_target",
    "name": "custom_check",
    "issued": 1525062240
  }
}

{
  "timestamp": "2018-04-30T06:24:00.349912+0200",
  "level": "info",
  "message": "publishing check result",
  "payload": {
    "client": "assensu.internal.defaultoute.eu",
    "check": {
      "command": "python3.6 /srv/custom_checks/custom_check.py",
      "ttl": 900,
      "handlers": [
        "default",
        "custom_handler"
      ],
      "source": "my_check_target",
      "name": "custom_check",
      "issued": 1525062240,
      "subscribers": [
        "remote-checks"
      ],
      "interval": 600,
      "executed": 1525062240,
      "duration": 0.337,
      "output": "Check OK",
      "status": 0
    }
  }
}

然后,日志停止生成有关支票的任何内容。 我无法找到任何我做错的事。我甚至添加了一行代码,一旦被调用就写入处理程序中的日志文件,但什么都没有 任何线索?
(如果你想知道,我使用的是python,因为我不熟悉ruby ...)

答案 0 :(得分:1)

处理程序仅在以下状态类型上执行:

  • 警告
  • 临界
  • 未知

https://docs.sensu.io/sensu-core/1.4/reference/handlers/#handler-attributes

搜索"严重性",了解如何在处理程序定义中自定义此属性。

事件是创建,解决或拍打。

https://docs.sensu.io/sensu-core/1.2/reference/events/#event-actions

您的客户端日志显示"状态:0",表示已通过检查,因此未创建任何事件,并且没有理由为该事件执行处理程序。尝试将支票设置为故意失败:sys.exit(2),以便"状态:2"将被报告,处理程序将执行。

处理程序可以处理已解决的事件类型。例如,您可能希望通过HipChat,Slack或Email通知事件已清除。 (即从"状态:2",到"状态:0")

我们如何查看检查事件状态的Python示例:

if data['check']['status'] > 2:
    level = "Unknown"
elif data['check']['status'] == 2:
    level = "Critical"
elif data['check']['status'] == 1:
    level = "Warning"
elif data['check']['status'] == 0:
    level = "Cleared"

我还要确保你的/srv/custom-sensu-handlers/handler.py由sensu:sensu用户/组递归拥有,因为它超出了默认的/ etc / sensu / plugins目录。
