I’m currently migration from Application Insights Telemetry to AzureMonitor and OtlpExporter and discovered that Role Instance no longer matches the name given by Helm chart. Instead it seem to get a random generated GUID. I’ve tried to turn off automatic generation when creating the resource but it doesn’t change the behavior.

services
  .AddOpenTelemetry()
  .UseAzureMonitor()
  .WithTracing(trace => {})
  .WithMetrics(metric => {});

I’ve also turned on RedisInstrumentation and that has the side effect of spamming with verbose logs and I can’t find how to turn them of. The SourceContext (from Serilog naming) can’t be found in the properties and I use Serilog as logger.
I’ve tried adding it using builder.Logging.AddOpenTelemetry() and use the OpenTelemetry Sink for Serilog.
