1、需求
之前一直是手動(dòng)的巡檢，然后貼圖，最近服務(wù)器數(shù)量大增，有點(diǎn)忙不過(guò)來(lái)了。因?yàn)橐恢庇玫膉ava，對(duì)shell腳本不是特別了解，所以這次用java寫了個(gè)小項(xiàng)目，實(shí)現(xiàn)對(duì)多服務(wù)器，多任務(wù)的巡檢，巡檢結(jié)果有故障的會(huì)通過(guò)郵件通知。
2、功能和效果
巡檢的項(xiàng)目主要是服務(wù)，硬盤，內(nèi)存等，命令可配置，巡檢結(jié)果以日期和服務(wù)器為基準(zhǔn)輸出文件，錯(cuò)誤信息通過(guò)郵件通知管理運(yùn)維人員。
3、代碼
