前幾天我們公司的一個服務器宕機了，ping不通ssh連不上。只好讓IDC機房工作人員幫我們重啟我們的服務器。重啟完之后趕緊查看日志，但是自身服務日志并沒有報錯。接下來就是分析硬件問題了。我們服務器是DELL的，經理讓我安裝了一個DELL 的檢測工具。
Dell System E-Support Tool (DSET）這個工具可以用來收集服務器硬件信息，存儲信息（RAID卡，硬盤等）。及linux 驅動，服務，網絡設置等等，同時又包括CPU，memory, ESM log, BIOS/firmware versions and system health (fan/voltage levels).
