如何將Rails日誌保存到應用程序之外的數據庫？

Question

我試圖將生產環境日誌保存到其他服務器上的數據庫..我的意思是，當出現一些錯誤時，我想打開ssh並檢查production.log的結尾。我想要的是去另一個數據庫（可能在其他服務器上）螞蟻檢查出來。

我想記錄的信息是相同的，因爲我在* .LOG看到，包含錯誤的代碼跟蹤，該錯誤發現行，數據庫查詢，以及HTTP響應..

像對此，

    Parameters: {"username_or_email"=>"admin", "action"=>"login", "authenticity_token"=>"oPMZYGi+k/Wvxxxxxv2oNU0w34PV2KNSENuwn8=", "controller"=>"admin/welcome", "password"=>"[FILTERED]"}

Answer 1

Rails logger顯然不能做你想要的東西。

一種選擇是寫入syslog（http://www.blueboxgrp.com/news/2009/06/unified_rails_logging_with_syslog-ng）並使用可將日誌條目推送到數據庫的syslog-ng（mysql，postgres ，sqlite，http://chaos.untouchable.net/index.php/HOWTO_setup_syslog-ng_to_log_to_mysql）。你必須做一些配置才能使這一切工作，再加上調整軌道來配置生產模式下的更多信息。問題在於，每當您的應用程序獲得請求時，它會多次寫入日誌，因此您會爲數據庫中的每個請求獲取多條記錄。

還有另一種服務，在今年Rails Rumble期間創建（抱歉插件！）http://logbook.me，您可以使用它來記錄任何內容。使用當前版本的gem，您需要手動執行一些工作（捕獲異常，捕獲您感興趣的細節+回溯並將它們傳遞給服務），但我們計劃擴展它以便它自動處理更多東西。
