# AL0089 - Missing OTLP configuration

> Configure OTLP endpoint explicitly

Source: [Al0089MissingOtlpConfigurationAnalyzer.cs](https://github.com/ANcpLua/ANcpLua.Analyzers/blob/main/src/ANcpLua.Analyzers/Analyzers/Al0089MissingOtlpConfigurationAnalyzer.cs)

## Description

OTLP exporter should have its endpoint explicitly configured rather than relying on the default `localhost:4317`, which often does not exist in production.

## Bad Code

```csharp theme={null}
builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter()); // default endpoint
```

## Good Code

```csharp theme={null}
builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter(o =>
        o.Endpoint = new Uri("https://collector.example.com:4317")));
```

## Properties

* **Category**: OpenTelemetry
* **Severity**: Warning
* **Enabled by default**: True
* **Code fix available**: False

## Configuration

```editorconfig theme={null}
dotnet_diagnostic.AL0089.severity = warning
```
