.net core使用App.Metrics+InfluxDB+Grafana进行APM监控

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.5.2.x86_64.rpm[/code] 
2、安装InfluxDB

rpm -ivh influxdb-1.5.2.x86_64.rpm


systemctl start influxdb.service


3、创建库、用户

influx


CREATE DATABASE qkaweb


use qkaweb


create user "leizhihui" with password '123456'


二、Grafana

1、下载、安装：

wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.1.2-1.x86_64.rpm[/code] 
yum localinstall grafana-5.1.2-1.x86_64.rpm


2、设置开机自动启动：

systemctl daemon-reload


systemctl enable grafana-server.service


3、启动服务并查看服务状态：

systemctl start grafana-server.service


systemctl status grafana-server.service


4、访问ip+3000端口，用户名和密码均为admin进行登录，

5、创建数据源，如下图所示：



6、导入Dashboard：





输入2125后点击Import按钮即导入App Metrics模板。

三、网关项目中添加App Metrics

1、添加下面nuget引用：

App.Metrics
App.Metrics.Extensions.Middleware
App.Metrics.Extensions.Mvc
App.Metrics.Extensions.Reporting.InfluxDB
App.Metrics.Extensions.Middleware
App.Metrics.Formatters.Json


2、修改appsettings.json文件：

"AppMetrics": {
"DataBaseName": "qkaweb",
"ConnectionString": "http://192.168.2.168:8086",
"UserName": "leizhihui",
"Password": "123456",
"App": "QkaWebApis",
"Env": "develop"
}


3、添加如下代码：

public void ConfigureServices(IServiceCollection services)
{

#region App Metrics
AppMetricsConfig appMetricsConfig = Configuration.GetSection("AppMetrics").Get<AppMetricsConfig>();
var uri = new Uri(appMetricsConfig.ConnectionString);

var metrics = AppMetrics.CreateDefaultBuilder()
.Configuration.Configure(
options =>
{
options.AddAppTag(appMetricsConfig.App);
options.AddEnvTag(appMetricsConfig.Env);
})
.Report.ToInfluxDb(
options =>
{
options.InfluxDb.BaseUri = uri;
options.InfluxDb.Database = appMetricsConfig.DataBaseName;
options.InfluxDb.UserName = appMetricsConfig.UserName;
options.InfluxDb.Password = appMetricsConfig.Password;
options.HttpPolicy.BackoffPeriod = TimeSpan.FromSeconds(30);
options.HttpPolicy.FailuresBeforeBackoff = 5;
options.HttpPolicy.Timeout = TimeSpan.FromSeconds(10);
options.FlushInterval = TimeSpan.FromSeconds(5);
})
.Build();

services.AddMetrics(metrics);
services.AddMetricsReportScheduler();
services.AddMetricsTrackingMiddleware();
services.AddMetricsEndpoints();
#endregion
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseMetricsAllMiddleware();
app.UseMetricsAllEndpoints();
}
