AspNet Core下利用 app-metrics+Grafana + InfluxDB实现高大上的性能监控界面
在日常系统工作中,我们为了洞察系统的问题和运作情况通常会记录日志的方式来进行分析,但是在很多情况下都是被动的在出问题后才会去查日志。在很多时候,我们可能更需要相对实时的了解整个系统或者某一时段的运行的情况,诸如系统出错的频率以及响应时间等等指标。这些动态的准实时信息对于监控整个系统的运行和健康状况非常重要,而本文的主角们能通过很好的配合帮助你实现这个目标,而且是一种高大上的实现方式。想想泡杯茶翘着二郎腿看着偌大的屏幕上有着一堆华丽的仪表和曲线图,即使看不懂也很牛B的样子啊!(谁知道我看得懂看不懂呢,是不是?)
Q: 那什么是App-Metrics?
A: App Metrics是一个开源和跨平台的.NET库,用于记录应用程序中各项指标。可以在.NET Core上运行,也可以在支持.NET 4.5.2的完整.NET框架上运行。
App Metrics对底层数据源做了很好的抽象以支持很多类型的数据库,例如:
InfluxDb、Prometheus、ElasticSearch等等。。
同时他又提供了很多Measurements比如Apdex, Gauges, Counters, Meters, Histograms 等等一大堆
1. 安装Grafana
Q: 什么是Grafana?
A: 一个类似Kibana的可视化数据开源程序,一般配合时间序列数据库进行配合来展示数据
这里为了方便使用docker来运行Grafana
docker run -d --name=grafana -p 3000:3000 grafana/grafana

接着我们确认下是否正常运行了
docker ps -a

2. 安装 InfluxDB
InfluxDb是比较流行的时序数据库,可以根据需要替换成Prometheus同上为了方便我们还是使用docker来运行
如果你希望每次都能保持之前docker运行收集的数据可以用docker 的-v选项把目录映射到本机的目录以便持久化数据
==注意influxdb有2个端口一个是admin一个database==
docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 tutum/influxdb
如图另外开一个控制台我们看到后台已经运行了2个容器

输入http://127.0.0.1:8083/ 访问InfluxDb的控制界面以便创建数据库



3. 配置AspNet Core2.x
先照常新建一个MVC项目
安装所需的第三方库
dotnet add package App.Metrics.Extensions.Mvc dotnet add package App.Metrics.Formatters.Json dotnet add package App.Metrics.Extensions.Reporting.InfluxDB
控制台显示安装成功! 
修改Startup.cs
using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; using App.Metrics.Configuration; using App.Metrics.Extensions.Reporting.InfluxDB; using App.Metrics.Extensions.Reporting.InfluxDB.Client; using App.Metrics.Reporting.Interfaces; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Hosting; using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.HttpsPolicy; using Microsoft.AspNetCore.Mvc; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; namespace WebApplication1 { public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } public void ConfigureServices(IServiceCollection services) { #region 注册 App-Metrics & 配置输出report到influxdb var database = "MyMetrics"; var uri = new Uri(" http://127.0.0.1:8086 "); //本地Docker中运行的influx实例,注意InfluxDb有2个端口别搞错 services.AddMetrics(options => { options.WithGlobalTags((globalTags, info) => { globalTags.Add("app", info.EntryAssemblyName); globalTags.Add("env", "stage"); }); }) .AddHealthChecks() .AddReporting( factory => { factory.AddInfluxDb( new InfluxDBReporterSettings { InfluxDbSettings = new InfluxDBSettings(database, uri), ReportInterval = TimeSpan.FromSeconds(5) }); }) .AddMetricsMiddleware(options => options.IgnoredHttpStatusCodes = new[] {404}); #endregion services.Configure<CookiePolicyOptions>(options => { options.CheckConsentNeeded = context => true; options.MinimumSameSitePolicy = SameSiteMode.None; }); //添加Metric Filter到mvc services.AddMvc(options => options.AddMetricsResourceFilter()) .SetCompatibilityVersion(CompatibilityVersion.Version_2_1); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IApplicationLifetime lifetime) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseExceptionHandler("/Home/Error"); app.UseHsts(); } app.UseHttpsRedirection(); app.UseStaticFiles(); app.UseCookiePolicy(); loggerFactory.AddConsole(Configuration.GetSection(" Logging ")); app.UseMetrics(); app.UseMetricsReporting(lifetime); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); }); } } }
接下来就是配置豪华的Grafana了!
打开浏览器试着访问docker内运行的Grafana容器,默认的用户名和密码是admin/admin 不用担心,第一次登录成功后系统会要求你重新设置新的密码,很贴心!!
登录成功后,配置Datasource当然是选择我们之前运行的InfluxDb

按图进行配置

提交后,如下图显示即配置成功

接着就是创建你的Dashboard,可以自己建立也可以自己配置json文件导入,网上有很多例子可以直接下载

技术和商业的碰撞,谈阿里云与天猫双11这十年
摘要:2009年,发生了两件看似不起眼的事。 初春刚过,阿里云在北京一栋没有暖气的写字楼写下了飞天第一行代码。 同年11月11日,淘宝商城启动了一个叫做双11的促销活动。 谁也没想到,多年以后他们会是现在这模样。 2009年,发生了两件看似不起眼的事。 初春刚过,阿里云在北京一栋没有暖气的写字楼写下了飞天第一行代码。 同年11月11日,淘宝商城启动了一个叫做双11的促销活动。 谁也没想到,多年以后他们会是现在这模样。 前传 2007年淘宝的交易额突破了400亿,技术团队却喜忧参半:现有集中式架构已经捉襟见肘,该如何应对? 随即启动的分布式改造获得巨大成功,淘宝所有的业务都做了模块化。 尽管这次技术升级在现在看来存在诸多局限性:更多的是为了应对不断增多的图片缓存,在CDN端对海量的图片缓存做了一些限流操作。但就是这次改造成就了历史上第一个双11,2009年双11当天的流量达到了一个高峰,在旧的架构体系下,这几乎是一项不可能完成的任务。 一年后,飞天的第一个版本上线,仅有几十台机器的集群开始服务第一个内部客户——阿里金融。 这些探索让所有人看到了一个趋势:用分布式的方法将传统、昂贵的小型机...

移动端Appium自动化测试框架的优势
众所周知,现在市面上的移动端操作系统已被Android和IOS占领,其中Android的份额更是在80%以上。那么面对市面上林林总总的自动化测试框架和工具,为什么说Appium在自动化测试框架的统治级优势呢,下面先看一下各大主流框架的对比及优势。 一、主流框架对比 下面对比了市面上主流的几大框架: 二、各大框架优缺点说明 1、Monkey是Android SDK自带的测试工具,在测试过程中会向系统发送伪随机的用户事件流,如按键输入、触摸屏输入、手势输入等),实现对正在开发的应用程序进行压力测试,也有日志输出。实际上该工具只能做程序做一些压力测试,由于测试事件和数据都是随机的,不能自定义,所以有很大的局限性。 2、MonkeyRunner也是Android SDK提供的测试工具。严格意义上来说MonkeyRunner其实是一个Api工具包,比Monkey强大,可以编写测试脚本来自定义数据、事件。缺点是脚本用Python来写,对测试人员来说要求较高,有比较大的学习成本。 3、Espresso是Google的开源自动化测试框架。相对于Robotium和UIAutomator,它的特点是规模...
