< 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 >

< 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 >

< p > 但 是 Grafana显 示 的 指 标 只 根 据 Namespace和 Pod两 层 来 分 类 ， 实 在 有 些 单 薄 ， 我 们 希 望 通 过 应 用 的 label增 加 service这 一 层 分 类 。 架 构 图 如 下 ： < / p >

< p > 这 种 方 式 有 以 下 几 个 要 点 ： < / p >
< ul >
< li > 访 问 kubernetes API获 取 应 用 Pod的 IP和 端 口 < / li >
< li > Pod labels作 为 监 控 metric的 tag< / li >
< li > 直 接 访 问 应 用 的 Pod的 IP和 端 口 获 取 应 用 监 控 数 据 < / li >

< p > 对 于 复 杂 的 应 用 编 排 和 依 赖 关 系 ， 我 们 希 望 能 够 有 清 晰 的 图 标 一 览 应 用 状 态 和 拓 扑 关 系 ， 因 此 我 们 用 到 了 Weaveworks开 源 的 < a href = "https://github.com/weaveworks/scope" target = "_blank" > scope< / a > 。 < / p >
