Hey all, do you support C++ apps?

Yes, any apps that are instrumented with https://github.com/open-telemetry/opentelemetry-cpp are supported.

I'm reading through that and baffled on how to connect to SigNos.. Any suggestions or examples?

We support OTLP protocol natively i.e instrument your code with cpp sdk and use OTLP exporter to send data and you should be able to use it action in signoz UI. https://github.com/open-telemetry/opentelemetry-cpp/tree/main/exporters/otlp#configuration-options--otlp-grpc-exporter-

OK coool. What about prometheus or opencensus interfaces?

They would require some config changes.
