[筆記] inxi 蒐集詳盡的硬體資訊 / inxi Collect Detail Hardware Info

Article Outline

最近因為一直碰到硬碟故障的問題,算起來那一批同時購買的5X顆 seagate 2T硬碟,已經有一半以上故障返修了....

然後又因為一直沒有添購新的硬碟,只能用這些快過保/已過保的撐著

所以最近不斷的在更換機器內的硬碟,而且還沒有熱插拔!

也導致原本負責處理盤點資產的同事困擾,因為跟手邊的紀錄已經對不起來了

然後就變成要對資產的時候,需要一台一台登入,然後去下不同的指令,取得想要的硬體資訊,超級麻煩的!

<!--more-->

幾次之後,終於決定透過ansible來做這件事

一開始的想法很簡單,就用 lshw/dmidecode這些指令去做

可是因為手邊的機器有ubuntu 18.04/16.04/14.04 , Debian 9 , Proxmox (based on debian ) , CentOS , FreeNAS

而有些系統預設沒有 lshw / dmidecode (對,FreeNAS 就是說你)

所以變成要依照系統不同,去下不同的指令,雖然都是ansible在跑,但是看到playbook的內容就很煩啊!

然後就不小心讓我翻到了 inxi 這個指令,根本就是救星啊!

直接來看輸出的範例

有沒有,是不是很優!

而且簡單易懂,還能抓到同事想看的資料,像是廠牌、型號、序號、記憶體類型(DDR2/3/4)

所以馬上捨棄 lshw/dmidecode ,改用 inxi 來跑

ansible role 的內容也很簡單

就偵測完之後,把結果送出給設定好的收件人

只是因為系統不同,大致上要分成 ubuntu/debian/centos 以及 freebsd 兩種

所以同樣的task 要跑兩次,一個要帶sudo 一個不用帶

然後BSD系列的機器,在inventory 裡面要帶入 ansible_ssh_user

就這樣,沒有什麼太困難的

inventory 內容

hqs01.abc.com ansible_ssh_host=192.168.11.1

bbs089.abc.com ansible_ssh_host=192.168.0.89 ansible_ssh_user=root

ansible 又發揮了一次,另外,感覺這個指令可以用來寫資產管理系統耶...威力強大

而且又不用管作業系統是什麼,反正有執行檔,直接派過去 remote 端就好了!

真是讓我相見恨晚啊!
