Linuxでハードディスクの温度を測定する

Linuxでハードディスクの温度を測定するには、以下のコマンドを利用します。

smartctl

※S.M.A.R.T.(スマート:Self-Monitoring, Analysis and Reporting Technology System)

オプションは以下の通り

オプション意味
-aすべての情報を表示する
-iハードディスクのS.M.A.R.T.サポート状況を表示する
-lエラーのログを表示する
-v温度やシークエラーなどの状況を表示する

これで、以下のように実行すると、ハードディスクの温度が見れます。

# smartctl -a /dev/sda | grep Temp
194 Temperature_Celsius     0x0022   105   086   000    Old_age   Always       -       38

ちなみに、全表示だと、こんな感じになります。
