Configuration
Here you will find App Metrics configuration options related to integrating App Metrics in an ASP.NET Core application.
App Metrics Core
Program.cs
When bootstrapping an ASP.NET Core application in Program.cs using the Microsoft.Extensions.Hosting.Host, App Metrics core functionality can be configured using extension methods provided on Microsoft.Extensions.Hosting.IHostBuilder.
Modifying or extending a MetricsBuilder that is pre-configured with the defaults configuration:
...
public static IHost BuidHost(string[] args)
{
return Host.CreateDefaultBuilder(args)
.ConfigureMetricsWithDefaults(
builder =>
{
builder.Configuration.Configure(
options =>
{
options.DefaultContextLabel = "Testing";
options.Enabled = false;
});
})
.UseMetrics()
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
.Build();
}
...
Using a MetricsBuilder where you define the desired configuration without defaults:
...
public static IHost BuidHost(string[] args)
{
return Host.CreateDefaultBuilder(args)
.ConfigureMetrics(
builder =>
{
builder.Configuration.Configure(
options =>
{
options.DefaultContextLabel = "Testing";
options.Enabled = false;
});
})
.UseMetrics()
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
.Build();
}
...
Startup.cs
Optionally, App Metrics core functionality can be configured in an ASP.NET Core application using the Startup.cs rather than bootstrapping on the Host. This is done by using the MetricsBuilder directly and the Microsoft.Extensions.DependencyInjection.IServiceCollection extension methods provided by App Metrics.
Modifying or extending a MetricsBuilder that is pre-configured with the defaults configuration:
public class Startup
{
public void Configure(IApplicationBuilder app)
{
app.UseMvc();
}
public void ConfigureServices(IServiceCollection services)
{
var metrics = AppMetrics.CreateDefaultBuilder()
... // configure other options
.Build();
services.AddMetrics(metrics);
services.AddMvc().AddMetrics();
}
}
Using a MetricsBuilder where you define the desired configuration without defaults:
public class Startup
{
public void Configure(IApplicationBuilder app)
{
app.UseMvc();
}
public void ConfigureServices(IServiceCollection services)
{
var metrics = new MetricsBuilder()
... // configure other options
.Build();
services.AddMetrics(metrics);
services.AddMvc().AddMetrics();
}
}
