我想解析nagios3的status.dat文件,並用python腳本輸出爲xml。 xml部分很簡單,但我該如何解析文件?使用多行正則表達式? 由於許多主機和服務都受到監控,文件可能會很大,將整個文件加載到內存中是否明智?
我只需要提取具有嚴重狀態和所屬主機的服務。如何解析nagios status.dat文件?
任何幫助和指向正確的方向將受到高度讚賞。
LE下面是該文件的外觀:

它可以有任意數量的主機和主機可以有任意數量的服務。
按照他們的文檔,Nagiosity「採取Nagios的實時狀態達達和輸出XML。」它自2011年以來一直未更新,但它只是一個小型的Python腳本。 – AnneTheAgile 2014-08-02 20:07:58
