Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

egg-prometheus

NPM version CI Test coverage npm download

为 egg 提供 Prometheus 功能支持

安装

npm i egg-prometheus --save

用法

开启插件

通过 ${app_root}/config/plugin.js 配置启动 Prometheus 插件:

exports.prometheus = {
  enable: true,
  package: "egg-prometheus",
};

配置

exports.prometheus = {
  timeout: 3000,
  scrapePort: 3000,
  scrapePath: '/metrics',
  defaultHttpMetricsFilter: ({ method, status, routerName, path }) => true,
  defaultLabels: { ... },
};
  • timeout: metrics 数据的拉取超时时间
  • scrapePort: 监听的用于采集 metrics 的端口
  • scrapePath: 监听的采集 metrics 的服务路径
  • defaultLabels: 默认的 metrics 标签,全局生效
  • defaultHttpMetricsFilter: 默认的 http metrics 的过滤函数,自定义过滤逻辑,返回 true 就是不过滤,返回 false 就是过滤

内置的 Metrics

  • http_response_time_ms summary: http 请求耗时
  • http_request_rate counter: http 请求数

当 egg-rpc-base 插件开启时,还会提供下面 metrics

  • rpc_consumer_response_time_ms summary: rpc 客户端请求耗时
  • rpc_consumer_request_rate counter: rpc 客户端请求数
  • rpc_consumer_fail_response_time_ms summary: rpc 客户端失败的请求耗时
  • rpc_consumer_request_fail_rate counter: rpc 客户端失败的请求数
  • rpc_consumer_request_size_bytes summary: rpc 请求大小统计
  • rpc_consumer_response_size_bytes summary: rpc 响应大小统计
  • rpc_provider_response_time_ms summary: rpc 服务端处理时间
  • rpc_provider_request_rate counter: rpc 服务端收到请求数
  • rpc_provider_fail_response_time_ms summary: rpc 服务端失败的请求处理时间
  • rpc_provider_request_fail_rate counter: rpc 服务端失败的请求数

自定义 Metrics

可以通过下面 API 自定义业务 metrics

const counter = new app.prometheus.Counter({
  name: "xxx_total",
  help: "custom counter",
  labelNames: ["xxx"],
});

const gauge = new app.prometheus.Gauge({
  name: "xxx_gauge",
  help: "custom gauge",
  labelNames: ["xxx"],
});

const histogram = new app.prometheus.Histogram({
  name: "xxx_histogram",
  help: "custom histogram",
  labelNames: ["xxx"],
});

const summary = new app.prometheus.Summary({
  name: "xxx_summary",
  help: "custom summary",
  labelNames: ["xxx"],
});
