shellスクリプトインスタンス--システムパフォーマンス分析
10159 ワード
スクリプトの目的:システムリソースのパフォーマンスボトルネックの分析
スクリプト機能:
1.CPU使用率と負荷の表示(top,vmstat,sar)
2.ディスクの表示、INode使用率とI/O負荷(df,iostat,iotop,sar,dstat)
3.メモリ使用率の表示(free,vmstat)
4.TCPリンク状態の表示(netstat,ss)
5.CPUとメモリの占有率が最も高い10個のプロセス(top,ps)を確認する
6.ネットワークトラフィックの表示(ifconfig,iftop,iptraf)
