I get asked about my default settings for Linux fairly frequently and was writing this in an email and decided to post it for broader use. If you have better recommendations, by all means please send me a pull request. The Edit button at the top of this page will get you there. There are a couple groups of settings below.

LVS ( Linux Virtual Server ) で DSR ( Direct Server Return ) のロードバランサ環境を、オーケストレーションツールの Serf を使って自動管理しよう、という内容です。当記事の検証は、CentOS 6.5 (x86_64)上で、Serf v0.4.5 を使用しています。 設定の方向性は、バランシング先のノードの増減を Serf を使って管理します。Serf のメンバに join する事で、自動的にバランシング先に組み込みます。また、障害発生時 ( fail ) やノードから離れる ( leave ) 時にも、自動的にバランシング情報の削除を試みました。 ◆ OSC 1014 Tokyo/Fall で登壇させて頂きました オープンソースカンファレンス 3月1日(土) 、オープンクラウドキャンパス枠で登壇させていただきました。内容は、オー

inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications. It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload. The inotifywait and inotifywatch commands (maintained by Eric Curtin as part of the inotify-tools project)
Linux has always been able to show how much I/O was going on (the bi and bo columns of the vmstat 1 command). Iotop is a Python program with a top like UI used to show of behalf of which process is the I/O going on. It requires Python ≥ 2.7 and a Linux kernel ≥ 2.6.20 with the TASK_DELAY_ACCT CONFIG_TASKSTATS, TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS options on.

Many Linux administrators and support technicians regularly use the top utility for real-time monitoring of their system state. In some shops, it is very typical to check top first when there is any sign of trouble. In that case, top becomes the de facto critical measurement of the machine's health. If top looks good, there must not be any system problems. top is rich with information—memory usage
