Prometheus 与 Grafana 监控方案

*在线运行 vLLM 入门教程:零基础分步指南

源码 examples/online_serving/prometheus_grafana

本示例演示如何将 vLLM 的指标数据接入 Prometheus/Grafana 监控栈。本例使用 Docker 启动 Prometheus 和 Grafana 服务,更多部署方式请参考 PrometheusGrafana 官方文档。

安装:

启动

Prometheus 指标日志记录在 OpenAI 兼容服务器中默认启用。通过入口点启动:

vllm serve mistralai/Mistral-7B-v0.1 \
--max-model-len 2048 \
--disable-log-requests

使用 docker compose 启动 Prometheus 和 Grafana 服务:

docker compose up

向服务器提交样本请求:

wget https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered/resolve/main/ShareGPT_V3_unfiltered_cleaned_split.json

python3 ../../../benchmarks/benchmark_serving.py \
--model mistralai/Mistral-7B-v0.1 \
--tokenizer mistralai/Mistral-7B-v0.1 \
--endpoint /v1/completions \
--dataset-name sharegpt \
--dataset-path ShareGPT_V3_unfiltered_cleaned_split.json \
--request-rate 3.0

访问 http://localhost:8000/metrics 即可查看 vLLM 暴露的原始 Prometheus 指标数据。

Grafana 仪表板

访问 http://localhost:3000,使用默认凭证登录(用户名:admin,密码:admin)。

添加数据源

访问 http://localhost:3000/connections/datasources/new 选择 Prometheus 数据源。

在 Prometheus 配置页面中,您需要在 Connection 部分添加 Prometheus Server URL。在本示例配置中,Grafana 和 Prometheus 运行于不同的容器,但 Docker 会为每个容器创建 DNS 名称。您可以直接使用 http://prometheus:9090

点击保存并测试 Save & Test。您将看到绿色的成功提示,显示 "Successfully queried the Prometheus API."。

导入仪表板

Navigate to http://localhost:3000/dashboard/import, upload grafana.json, and select the prometheus datasource. You should see a screen that looks like the following:

访问 http://localhost:3000/dashboard/import,上传 grafana.json 文件,并选择 prometheus 数据源。您将看到如下所示的界面:

# docker-compose.yaml
version: "3"

services:
prometheus:
image: prom/prometheus:latest
extra_hosts:
- "host.docker.internal:host-gateway" # allow a direct connection from container to the local machine # 允许容器直接连接宿主机
ports:
- "9090:9090" # the default port used by Prometheus # Prometheus 默认服务端口
volumes:
- ${PWD}/prometheus.yaml:/etc/prometheus/prometheus.yml # mount Prometheus config file # 挂载 Prometheus 配置文件

grafana:
image: grafana/grafana:latest
depends_on:
- prometheus
ports:
- "3000:3000" # the default port used by Grafana # Grafana 默认服务端口
