用于 Python 应用的 Prometheus 指标监控库,支持 Flask、Requests 和消息队列消费者的监控指标自动收集。

功能特性

  • ✅ 内置三大监控维度
    • Web 服务内部指标(Flask)
    • 合作商 HTTP 调用指标(Requests)
    • 消息队列消费指标(Consumer)
  • ✅ Prometheus 原生集成
  • ✅ 灵活的指标桶配置
  • ✅ 自动化的指标收集
  • ✅ 合作商接口预配置

安装使用

pip install channel_exporter

环境要求

  • Python 2.7+
  • 可选依赖(安装即监控):
    • Flask (Web 服务监控)
    • requests (HTTP 调用监控)
    • ctec_consumer (消费者监控)

快速开始(Web 服务指标)

# coding:utf-8
import channel_exporter
from flask import Flask

app = Flask(__name__)


@app.get("/")
def hello():
    return "Hello World!"


if __name__ == "__main__":
    # 初始化监控配置
    channel_exporter.__init__("<your_syscode>")

    # 启动后访问 /metrics 获取指标
    app.run()

配置说明

初始化参数

参数名 类型 必填 默认值 说明
syscode str 10位服务编码,格式:大写字母+9位数字
inner_metrics_buckets tuple 默认桶 Web 服务耗时分布桶
partner_http_metrics_buckets tuple 默认桶 HTTP 调用耗时分布桶
consumer_metrics_buckets tuple 默认桶 消费者耗时分布桶
default_metrics_port int 9166 指标默认暴露端口

指标说明

Web 服务指标

  • path: 请求路径
  • http_status: HTTP 状态码
  • code: 业务响应码
  • method_code: 接口编号

HTTP 调用指标

指标名称:partner_http_metrics

标签说明:

  • appid: 应用ID(syscode前4位)
  • application: 系统编码
  • partner: 合作商(域名)编号
  • action_code: 动作(路径)编号
  • http_status: HTTP 状态码
  • code: 业务响应码(由业务方定义,-1表示未找到业务响应码)

消费者指标

指标名称:[syscode]_consumer_metrics

标签说明:

  • appid: 应用ID(syscode前4位)
  • application: 完整syscode
  • f_code: 空值
  • topic: 消息主题
  • code: 处理结果(0成功/1失败)
