今回は、プログラムごとのコアメモリ使用量を出力するコマンド『ps_mem』を紹介する。
1.インストール
まずはインストールから。
以下のコマンドを実行する。
RHEL系
sudo yum install ps_mem -yDebian/Ubuntu系
git clone https://github.com/pixelb/ps_mem/
sudo cp ./ps_mem/ps_mem.py /sbin/ps_mem以上。
2.コマンドの実行
それでは、実際にコマンドを実行してみよう。

=================================その他、「-w <実行間隔(秒)>」を指定することで定期的にコマンドを実行させることができるようになる。
標準出力を別ファイルに書き出させ、ログとして利用することも可能だろう。
