输入和输出集成概述
HTTP 插件允许从指定的 HTTP 端点收集指标,处理各种数据格式和身份验证方法。
此插件使用基于 HTTP 的 Prometheus remote write 协议将指标从 Telegraf 发送到 Thanos,从而实现高效且可扩展地摄取到 Thanos Receive 组件中。
集成详情
HTTP
HTTP 插件从一个或多个 HTTP(S) 端点收集指标,这些端点应具有以受支持的输入数据格式之一格式化的指标。它还支持来自 secret-stores 的密钥,用于各种身份验证选项,并包含全局支持的配置设置。
Thanos
Telegraf 的 HTTP 插件可以通过其兼容 Remote Write 的 Receive 组件直接将指标发送到 Thanos。通过将数据格式设置为 `prometheusremotewrite`,Telegraf 可以将指标序列化为原生 Prometheus 客户端使用的基于 protobuf 的相同格式。此设置实现了高吞吐量、低延迟的指标摄取到 Thanos 中,从而促进了大规模的集中式可观测性。它在混合环境中特别有用,在这些环境中,Telegraf 从 Prometheus 原生范围之外的系统(例如 SNMP 设备、Windows 主机或自定义应用程序)收集指标,并将它们直接流式传输到 Thanos,以进行长期存储和全局查询。

输入和输出集成示例
HTTP
- 从 Localhost 收集指标:该插件可以从 HTTP 端点(如 `http://localhost/metrics`)获取指标,从而实现简单的本地监控。
- 使用 Unix 域套接字:您可以使用 http+unix 方案指定从通过 Unix 域套接字的服务收集指标,例如 `http+unix:///path/to/service.sock:/api/endpoint`。
Thanos
-
无代理云监控:在云虚拟机上部署 Telegraf 代理以收集系统和应用程序指标,然后使用 Remote Write 将它们直接流式传输到 Thanos。这提供了集中式可观测性,而无需在每个位置都部署 Prometheus 节点。
-
可扩展的 Windows 主机监控:在 Windows 机器上使用 Telegraf 收集操作系统级别指标,并通过 Remote Write 将它们发送到 Thanos Receive。这实现了跨异构环境的可观测性,而原生 Prometheus 仅在 Linux 上支持。
-
跨区域指标联邦:多个地理区域中的 Telegraf 代理可以使用此插件将数据推送到区域本地的 Thanos Receivers。从那里,Thanos 可以全局去重和查询指标,从而降低延迟和网络出口成本。
-
将第三方数据集成到 Thanos 中:使用 Telegraf 输入从自定义遥测源(例如 REST API 或专有日志)收集指标,并通过 Remote Write 将它们转发到 Thanos。这会将非原生数据带入 Prometheus 兼容的长期分析管道中。
