Sensu 补救措施：无法在客户端触发

Sensu 补救措施：无法在客户端触发

我是 Sensu 修复的新手。我尝试使用自定义脚本重新启动进程。

场景：如果我的 http 链接断开，那么我想手动运行脚本并启动它。

我尝试了 sensu 上的修复，它允许在监控出现问题时自动运行脚本，并使用自定义脚本进行监控检查。然而，我面临的问题是，所有检查和连接都很好，但当我的链接断开时，sensu 修复程序不会触发客户端。我已经发布了日志和配置，请告诉我我哪里出错了……

这是 Sensu 服务器日志

这是我在 Sensu-server 上的检查文件......

{
    "checks": {
            "check-zubron-port": {
                    "command": "/etc/sensu/plugins/check_http -H 10.0.0.110 -p 7077",
                    "interval": 60,
                    "occurrences": 2,
                    "handlers": [
                            "remediator"
                    ],
                    "subscribers": [
                            "zubron"
                    ],
                    "standalone": false,
                    "remediation": {
                            "remediate-zubron": {
                                    "occurrences": [
                                            1,
                                            3
                                    ],
                                    "severities": [
                                            2
                                    ]
                            },
                            "trigger_on": [
                                    "zubron"
                            ]


                  }
                }
        }
}

这是我的补救文件...

{
        "remediate-zubron": {
            "command": "sudo /bin/bash ~/zubron/home/moofwd-zubron-server/bin/start-moofwd.sh",
            "handlers": [],
            "subscribers": [
                "zubron"
            ],
            "standalone": false,
            "publish": false
    }
}

我从这里使用了 Rest sensu.rb关联

我是否遗漏了什么？

如果出现任何问题，是否有其他监控系统可供我们运行脚本或命令？

我已经尝试过 nagios nectar 和 monit。

我发现您的补救文件有错误。您缺少“检查”键。

应该是这样的，

{
    "checks": {
        "remediate-zubron": {
            "command": "sudo /bin/bash ~/zubron/home/moofwd-zubron-server/bin/start-moofwd.sh",
            "handlers": [],
            "subscribers": [
                "zubron"
            ],
            "standalone": false,
            "publish": false
        }
    }
}

  1. 其他一些可能的问题是您的客户端配置应该订阅您的名称，即名称university应该university在订阅者中订阅。

    {
    "client": {
        "name": "university",
        "address": "IP ADDRESS",
        "subscriptions": [
          "linux", "web-server", "system", "university"
        ]
    }
}

  2. 另一个问题可能与 remedediator.rb 或 sensu.rb 中的 api_request(:POST) 有关，以下方法应与下面给出的完全相同。在某些旧代码中，它有 ，'/checks/request'而不是 ，'/request'并导致中断。

    def trigger_remediation(check, subscribers)
    api_request(:POST, '/request') do |req|
        req.body = JSON.dump('check' => check, 'subscribers' => subscribers)
    end
end

  3. 在某些情况下，您需要同时修复情况 2 和情况 3。

以下是参考链接。让您更清楚地了解该问题。
