一般F5（LTM）的巡檢內容包括收集當前的ucs配置備份、收集qkview自檢包、日誌打包，記錄當前node、pool、vs的總數量、可用數量、異常數量、爲知數量等等。
由於F5的底層Linux做了很多的限制，所以獲取F5的很多信息只能通過snmp來實現，請保證F5的snmp使用的是v2c版本，團體名可以自行修改變量，允許127.0.0.1訪問。

PS：v10版本的上次切換時間顯示，是虛擬機的問題，真機並無問題。
最後拿到的壓縮包中，是ucs配置備份，qkview自檢文件，/var/log目錄下的所有日誌文件，過濾ltm日誌文件中所有包括err等錯誤關鍵字的日誌條目，還有就是單獨出現的這個inspection.log文件。
