Fluentd v11 設計案

We made it possible. Next, we'll make it beautiful.

Suffering-oriented programming

コンセプト

• 柔軟性向上
• 予想以上に複雑な使い方をしているケースが多かったので、設定ファイルも複雑化して対応する

Fluentd v11 内部ルーティングラベルの実装案あれこれ

Fluentd v11 設計案 の「1. 内部ルーティングラベルの導入」について、続き。

実装方法

案1. 新しいメタデータ「label」を導入する

• プラグインは、emitするときにlabelを指定することができる（省略可能）
• Engine.emit(tag, time, record[, label])

SmartMachine 生存指南

by fcicq, CC-BY

SmartMachine 是 Joyent 家的虚拟化方案.
SmartOS 主要的卖点是 ZFS + DTrace + Zones (SmartMachine) + KVM (运行 Linux, Windows 等).
实际上 SmartOS 是 Joyent 以 Solaris 为基础 (因为 OpenSolaris 项目被中止而改名 illumos) 打包的操作系统.

SmartOS 作为 HOST 时, 虽然支持 KVM 虚拟化, 但不支持突发的 vCPU.
而 SmartMachine 是基于 Zones 的 (存储则是 ZFS), 比较类似 Linux 平台下 OpenVZ 或者 LXC 的方案.
资源用量由调度器决定, 只需要修改配额 (ZFS 也支持在线扩展) 就可以伸缩, 所以伸缩不需要重启.
