sensu-client 检查内存样本工作正常

Question

我正在尝试让 sensu 工作。

以下是sensu-client.log

ubuntu@ip:~$ sudo tail -f  /var/log/sensu/sensu-client.log 
{"timestamp":"2016-09-27T16:07:37.628182-0400","level":"info","message":"completing checks in progress","checks_in_progress":[]}

/etc/sensu/client.json 包含

{
"rabbitmq": {
    "host": "ipaddressofsensuserver",
    "port": 5672,
    "user": "username",
    "password": "password",
    "vhost": "/sensu"
  },
  "api": {
    "host": "localhost",
    "port": 4567
  },
  "checks": {
    "test": {
      "command": "echo -n OK",
      "subscribers": [
        "test"
      ],
      "interval": 60
    },
    "memory-percentage": {
      "command": "check-memory-percent.sh -w 50 -c 70",
      "interval": 10,
      "subscribers": [
        "test"
      ]
     }
  },
  "client": {
    "name": "localhost",
    "address": "127.0.0.1",
    "subscriptions": [
      "test"
    ]
  }
}

我已将 check-memory-present.sh 复制到 /etc/sensu/conf.d 文件夹中

我希望日志文件每 10 秒运行 check-memory-percent。我在这里错过了什么？

Answer 1

在 Client.json 中，在 "client" 下，您需要添加订阅。就像在示例 here 中一样。它应该与您检查的 "subscribers" 的定义相匹配。

Answer 2

Sensu 客户端不能完全独立于服务器运行，但它可以将自己的检查安排到运行并通过传输（在本例中为 RabbitMQ）将它们发送到服务器。您必须将 "standalone": true 添加到检查配置才能生效，然后重新启动 sensu-client 服务。

因此，文件 /etc/sensu/conf.d/check_mem.json 应该类似于：

"checks": {
  "memory-percentage": {
    "command": "/etc/sensu/conf.d/check-memory-percent.sh -w 50 -c 70",
    "interval": 10,
    "standalone": true
  }
}

记得也从 /etc/sensu/client.json 中删除块，因为如果多次定义相同的检查名称，您可能会得到意想不到的结果。
