Using separate exporters for tracing and metrics

[xelossan]

Is it possible to configure separate exporters for traces and metrics? We'd like to use two instances of Application Insights and Log Analytics, one with sampling for traces, requests, errors etc. and the second one, without any limits and sampling, for metrics.

When calling AddOpenTelemetry and UseAzureMonitor mutiple times, it looks like the last configurations wins and everything is sent to the instance the was configured as the last one.

It is, yes.

Either you can override signal-specific environment variables:

• OTEL_EXPORTER_OTLP_LOGS_ENDPOINT
• OTEL_EXPORTER_OTLP_METRICS_ENDPOINT
• OTEL_EXPORTER_OTLP_TRACES_ENDPOINT

Or you can override signal-specific options to apply overrides with code:

services.AddOpenTelemetry()
        .WithLogging(builder => builder.AddOtlpExporter(o => o.Endpoint = new Uri("...")))
        .WithMetrics(builder => builder.AddOtlpExporter(o => o.Endpoint = new Uri("...")))
        .WithTracing(builder => builder.AddOtlpExporter(o => o.Endpoint = new Uri("...")));
