遥测和监控
AI 群集网络需要无损、高吞吐量和低延迟的连接。维护性能的一个关键组件是收集和分析运营数据，以监控拥塞、系统运行状况和流量模式。Junos OS 遥测可以详细跟踪关键性能指标，包括特定于 AI 工作负载的阈值、计数器和拥塞指标。收集数据后，必须对这些数据进行分析、结构化和可视化，以支持监控、决策和持续网络优化。
以下部分介绍如何配置设备以启用数据收集，并概述了推荐用于 AI EVPN/VXLAN 交换矩阵解决方案的关键性能指标。
配置 QFX 交换机以提供遥测信息
要实施遥测收集，需要将交换机配置为允许基于 gPRC 的访问，如《Junos 遥测接口用户指南》中的 OpenConfig 和 gRPC for Junos 遥测接口 部分所述。
为此，所有叶节点和主干节点设备上都使用了以下配置：
user@spine1> show configuration system services extension-service
request-response {
grpc {
ssl {
port 32767;
local-certificate aos_grpc;
}
routing-instance mgmt_junos;
}
}
表49.适用于 Junos OS 的 gRPC 配置命令
| 命令 | 说明 |
|---|---|
extension-service request-response grpc |
在扩展服务框架下启用 gRPC 接口，用于 Junos 遥测接口 （JTI） 或第三方集成等 API。客户端发出请求并等待 Junos OS 服务器的响应。 |
ssl port 32767 |
配置 TCP 端口 32767 以便使用 SSL 加密进行通信。 |
local-certificate aos_grpc |
使用名为 aos_grpc 的证书配置身份验证，以保护 gRPC 会话。请按照 配置 gRPC 服务 中所述的步骤生成并安装必要的证书。 |
routing-instance mgmt_junos |
将 gRPC 服务器绑定到mgmt_junos路由实例，这意味着它仅侦听带外管理接口。 |
要验证遥测收集器之间的连接，请使用命令 show system connections 并搜索配置的 SSL 端口号。
jnpr@stripe2-leaf1> show system connections | match "Address|32767" Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp6 0 0 :::32767 :::* LISTEN 11937/jsd tcp6 0 0 10.161.33.38:32767 10.100.1.17:56634 ESTABLISHED 11937/jsd tcp6 0 0 10.161.33.38:32767 10.100.1.20:53184 ESTABLISHED 11937/jsd tcp6 0 0 10.161.33.38:32767 10.100.1.20:53170 ESTABLISHED 11937/jsd
示例输出显示来自两个收集器（10.100.1.17 和 10.100.1.20）的连接。
要确认收集器正在通过 gRPC/gNMI 主动提取数据并查看 正在使用哪些传感器， 请使用：
