## Methods
### AddTraconHealthChecks\(IHealthChecksBuilder, string, IEnumerable?\)
Registers the Tracon health check. The consumer sets up its own `/health` path.
```csharp
public static IHealthChecksBuilder AddTraconHealthChecks(this IHealthChecksBuilder builder, string name = "tracon", IEnumerable? tags = null)
```
#### Parameters
`builder` [IHealthChecksBuilder](https://learn.microsoft.com/dotnet/api/microsoft.extensions.dependencyinjection.ihealthchecksbuilder)
The health checks builder.
`name` [string](https://learn.microsoft.com/dotnet/api/system.string)
The name of the check. Default is `tracon`.
`tags` [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable\-1)<[string](https://learn.microsoft.com/dotnet/api/system.string)\>?
Tags to add to the check. Example: readiness/liveness separation.
#### Returns
[IHealthChecksBuilder](https://learn.microsoft.com/dotnet/api/microsoft.extensions.dependencyinjection.ihealthchecksbuilder)
The builder, for chaining.
#### Remarks
Tracon does not call `MapHealthChecks` — taking over the consumer's path
choice would break the no-surprises rule. Setup:
```csharp
builder.Services.AddHealthChecks().AddTraconHealthChecks();
app.MapHealthChecks("/health");
```
The check reads [TraconDiagnosticsCollector](/api/tracon.tracondiagnosticscollector/); it produces no
model call. For the three states, see [Tracon.TraconHealthCheck](/api/tracon/).
This call only adds a service registration; whether `AddTracon` is
called before or after it does not matter (DI registration is order-independent).
However, if `AddTracon` is never called, [TraconDiagnosticsCollector](/api/tracon.tracondiagnosticscollector/)
cannot be resolved on the first `/health` probe and DI raises a clear error.
#### Exceptions
[ArgumentNullException](https://learn.microsoft.com/dotnet/api/system.argumentnullexception)
`builder` is [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null).
[ArgumentException](https://learn.microsoft.com/dotnet/api/system.argumentexception)
`name` is empty.
