1. 安装依赖包
在web项目打开nuget包管理器搜索 MiniProfiler.Mvc5和MiniProfiler.EF6安装。
2. 在Global.asax中添加配置代码

protected void Application_Start()
{
MiniProfiler.Configure(new MiniProfilerOptions
{
// Sets up the route to use for MiniProfiler resources:
// Here, ~/profiler is used for things like /profiler/mini-profiler-includes.js
RouteBasePath = "~/profiler",
// Example of using SQLite storage instead
Storage = new SqliteMiniProfilerStorage(ConnectionString),
// Different RDBMS have different ways of declaring sql parameters - SQLite can understand inline sql parameters just fine.
// By default, sql parameters will be displayed.
//SqlFormatter = new StackExchange.Profiling.SqlFormatters.InlineFormatter(),
// These settings are optional and all have defaults, any matching setting specified in .RenderIncludes() will
// override the application-wide defaults specified here, for example if you had both:
// PopupRenderPosition = RenderPosition.Right;
// and in the page:
// @MiniProfiler.Current.RenderIncludes(position: RenderPosition.Left)
// ...then the position would be on the left on that page, and on the right (the application default) for anywhere that doesn't
// specified position in the .RenderIncludes() call.
PopupRenderPosition = RenderPosition.Right, // defaults to left
PopupMaxTracesToShow = 10, // defaults to 15
// ResultsAuthorize (optional - open to all by default):
// because profiler results can contain sensitive data (e.g. sql queries with parameter values displayed), we
// can define a function that will authorize clients to see the JSON or full page results.
// we use it on http://stackoverflow.com to check that the request cookies belong to a valid developer.
ResultsAuthorize = request => request.IsLocal,
// ResultsListAuthorize (optional - open to all by default)
// the list of all sessions in the store is restricted by default, you must return true to allow it
ResultsListAuthorize = request =>
{
// you may implement this if you need to restrict visibility of profiling lists on a per request basis
return true; // all requests are legit in this example
},
// Stack trace settings
StackMaxLength = 256, // default is 120 characters
// (Optional) You can disable "Connection Open()", "Connection Close()" (and async variant) tracking.
// (defaults to true, and connection opening/closing is tracked)
TrackConnectionOpenClose = true
}
// Optional settings to control the stack trace output in the details pane, examples:
.ExcludeType("SessionFactory") // Ignore any class with the name of SessionFactory)
.ExcludeAssembly("NHibernate") // Ignore any assembly named NHibernate
.ExcludeMethod("Flush") // Ignore any method with the name of Flush
.AddViewProfiling() // Add MVC view profiling (you want this)
// If using EntityFrameworkCore, here's where it'd go.
// .AddEntityFramework() // Extension method in the MiniProfiler.EntityFrameworkCore package
);
// If we're using EntityFramework 6, here's where it'd go.
// This is in the MiniProfiler.EF6 NuGet package.
// MiniProfilerEF6.Initialize();
}
protected void Application_BeginRequest()
{
// You can decide whether to profile here, or it can be done in ActionFilters, etc.
// We're doing it here so profiling happens ASAP to account for as much time as possible.
if (Request.IsLocal) // Example of conditional profiling, you could just call MiniProfiler.StartNew();
{
MiniProfiler.StartNew();
}
}
protected void Application_EndRequest()
{
MiniProfiler.Current?.Stop(); // Be sure to stop the profiler!
}
3. 在web.config中添加js配置
1
<add name="MiniProfiler" path="profiler/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
4. 在需要的页面添加显示监控代码（所有页面可以在layout.cshtml中添加）
4.1 添加命名空间
@using StackExchange.Profiling;
4.2 在body块最后添加显示代码
@MiniProfiler.Current.RenderIncludes(position: RenderPosition.Right, showTrivial: false, showTimeWithChildren: true)
