#### Metrics in ServiceComb Java Chassis 1.0.0-m1 让微服务运行状态清晰可见 郑扬勇 微服务架构师 开源能力中心 ## 目录 • Metrics简介 • 基于BMI示例演示 • Metrics技术细节 ## Metrics是什么 - 直译是 “度量”， 不同的领域定义有所区别， 在微服务领域中的定义： “对微服务的某个指标给予一个可量化程度的测量” “对微服务的某个指标给予一个可量化程度的测量” • Metrics应该具备的特性: - Comparative（可对比）：指标能够在不同的微服务或同一个微服务的多个实例之间比较； • Understandable（易理解）：指标所衡量的对象、计算方法和输出的结果值都是容易理解的； • Ratio（理想的比例）：理想结果可预见，可以立即用于比较。 ## 最常见的Metrics - 衡量Metrics实现优劣的标准： - 无侵入或低侵入  ## Metrics的分类 • Metrics有很多种分类方式，在技术实现上我们偏向以取值方式区分为两种： • 1. 直接取值 - 任何时候都能够立刻获取到最新值，例如资源使用率，包括CPU使用率，线程数，Heap使用数据

Use a metrics plugin. This is the most feature-rich and flexible way to track broker metrics, although it requires tools (e.g. Prometheus) to store the metrics and display them (e.g. Grafana) to "disable" a queue so that messages are not routed to it • Support JVM GC & thread metrics • Support for resetting queue properties by unsetting them in broker.xml • Undeploy diverts by

Noted that this name(s)will also be used in model_name tag content of prometheus metrics, if multiple names provided, metricstag will take the first one. --qlora-adapter-name-or-path Name ## 1.15 Production Metrics vLLM exposes a number of metrics that can be used to monitor the health of the system. These metrics are exposed via the /metrics endpoint on the vLLM OpenAI compatible compatible API server.
