okhttp3-metrics-prometheus

Okhttp 3.x Metrics For Prometheus

组件简介

基于 okhttp 3.x + micrometer 的 Prometheus 指标采集组件，用于采集 okhttp 3.x 的连接池指标数据，包括：连接池活跃连接数、连接池空闲连接数、连接池最大连接数、连接池最大空闲连接数、连接

参考：https://github.com/raskasa/metrics-okhttp

使用说明

1、Spring Boot 项目添加 Maven 依赖

<dependency>
    <groupId>com.github.hiwepy</groupId>
    <artifactId>okhttp3-metrics-prometheus</artifactId>
    <version>${project.version}</version>
</dependency>

2、在`application.yml`文件中增加如下配置

################################################################################################################
###okhttp3基本配置：
################################################################################################################
okhttp3:
  # okhttp3 的 metrics 配置
  metrics:
    # 是否在监控指标中包含host标签
    include-host: true

2、使用示例

访问本地配置：
