Sensu 修復：無法在客戶端觸發

我是 Sensu 修復的新手。我嘗試使用自訂腳本重新啟動進程。

Senario：如果我的 http 連結斷開，那麼我想手動運行腳本並啟動它。

我嘗試了對 sensu 進行修復，如果您的監控出現問題，可以使用用於監控檢查的自訂腳本自動執行腳本。然而我面臨的問題是所有檢查和連接都很好，但是當我的連結斷開時，sensu remediator 不會觸發客戶端。我已經發布了日誌和配置請告訴我哪裡出錯了..

這是 Sensu 伺服器日誌

這是我在 Sensu-server 上的檢查文件...

{
    "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"
                            ]


                  }
                }
        }
}

這是我的修復文件...

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

其餘的 sensu.rb 我用過這個關聯

我有什麼遺漏的嗎？

如果出現任何問題，是否還有其他監控系統可以執行腳本或命令？

我已經嘗試過 nagios nectar 和 monit。

我在您的修復文件中看到一個錯誤。您缺少“檢查”鍵。

應該是這樣的，

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

  1. 其他可能的問題是您的客戶端配置應該訂閱您的名字，即名稱university應該university在訂閱者中訂閱。

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

  2. 另一個問題可能是 remeddiator.rb 或 sensu.rb 中的 api_request(:POST) ，以下方法應與下面給出的完全相同。在一些舊程式碼中，它'/checks/request'代替'/request'並導致損壞。

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

  3. 在某些情況下，您需要同時修復案例 2 和案例 3。
