< p > 在 前 面 的 < a href = "heapster-addon-installation.html" > 安 装 heapster插 件 < / a > 章 节 ， 我 们 已 经 谈 到 Kubernetes本 身 提 供 了 监 控 插 件 作 为 集 群 和 容 器 监 控 的 选 择 ， 但 是 在 实 际 使 用 中 ， 因 为 种 种 原 因 ， 再 考 虑 到 跟 我 们 自 身 的 监 控 系 统 集 成 ， 我 们 准 备 重 新 造 轮 子 。 < / p >
< p > 针 对 kubernetes集 群 和 应 用 的 监 控 ， 相 较 于 传 统 的 虚 拟 机 和 物 理 机 的 监 控 有 很 多 不 同 ， 因 此 对 于 传 统 监 控 需 要 有 很 多 改 造 的 地 方 ， 需 要 关 注 以 下 三 个 方 面 ： < / p >
< ul >
< li > Kubernetes集 群 本 身 的 监 控 ， 主 要 是 kubernetes的 各 个 组 件 < / li >
< li > kubernetes集 群 中 Pod的 监 控 ， Pod的 CPU、 内 存 、 网 络 、 磁 盘 等 监 控 < / li >

< p > 跟 物 理 机 器 和 虚 拟 机 的 监 控 不 同 ， 在 kuberntes集 群 中 的 监 控 复 杂 度 更 高 一 些 ， 因 为 多 了 一 个 虚 拟 化 层 ， 当 然 这 个 跟 直 接 监 控 docker容 器 又 不 一 样 ， kubernetes在 docker之 上 又 抽 象 了 一 层 service的 概 念 。 < / p >
< p > 在 kubernetes中 的 监 控 需 要 考 虑 到 这 几 个 方 面 ： < / p >
< ul >
< li > 应 该 给 Pod打 上 哪 些 label， 这 些 label将 成 为 监 控 的 metrics。 < / li >
< li > 当 应 用 的 Pod漂 移 了 之 后 怎 么 办 ？ 因 为 要 考 虑 到 Pod的 生 命 周 期 比 虚 拟 机 和 物 理 机 短 的 多 ， 如 何 持 续 监 控 应 用 的 状 态 ？ < / li >
< li > 更 多 的 监 控 项 ， kubernetes本 身 、 容 器 、 应 用 等 。 < / li >
< li > 监 控 指 标 的 来 源 ， 是 通 过 heapster收 集 后 汇 聚 还 是 直 接 从 每 台 主 机 的 docker上 取 ？ < / li >
