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 Telegraf 能够将指标直接实时流式传输到 Grafana 仪表板,利用 Grafana Live 实现即时数据可视化和操作洞察。
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,并包括全局支持的配置设置。
Grafana
Telegraf 可以使用 Websocket 输出插件将实时数据发送到 Grafana。Telegraf 收集的指标会立即推送到 Grafana 仪表板,从而实现实时可视化和分析。此插件非常适合需要低延迟、实时数据可视化的用例,例如操作监控、实时分析和即时事件响应场景。它支持身份验证标头、可自定义的数据序列化格式(如 JSON)和通过 TLS 的安全通信,在动态、交互式仪表板环境中提供了灵活性和易于集成性。

输入和输出集成示例
HTTP
- 从本地主机收集指标: 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。
Grafana
-
实时基础设施仪表板: 部署 Telegraf 以将服务器健康状况指标直接流式传输到 Grafana 仪表板,使 IT 团队能够实时可视化基础设施性能。此设置允许立即检测和响应关键系统事件。
-
交互式物联网监控: 集成 Telegraf 收集的物联网设备指标,并将实时数据推送到 Grafana,从而创建动态和交互式仪表板,用于监控智慧城市项目或制造过程。这种实时可见性显着提高了响应速度和运营效率。
-
即时应用程序性能分析: 将来自生产环境的应用程序指标实时流式传输到 Grafana 仪表板,使开发团队能够在部署期间快速检测和诊断性能瓶颈或异常,从而最大限度地减少停机时间并提高可靠性。
-
实时事件分析: 在大型现场活动期间,利用 Telegraf 捕获和流式传输实时受众或系统指标,直接传输到 Grafana 仪表板。活动组织者可以动态监控并对不断变化的条件或趋势做出反应,从而显着增强受众参与度和运营决策能力。
