.Net Application -> OpenTelemetry Collector -> AppDynamics

Yujie_Zhou1 — Fri, 27 Jan 2023 17:55:01 GMT

Hi all,

I'm developing a POC using otel collector (running on docker) to collect logs, traces, and metrics from a dotnet application and then send the observability data to AppDynamics. I'm following this section of the documentation: https://docs.appdynamics.com/appd/22.x/22.6/en/application-monitoring/appdynamics-for-opentelemetry

Currently I only see traces in the example configuration. Does anyone know if logs and metrics are also supported? And do I need to install dotnet agent to do this (given that I just want to see data successfully received in AppDynamics)?

Thank you for the help!

Regards,

Hi @Yujie.Zhou,

I did some asking around and Otel is currently not supported by the Trial/Lite version of AppD.

On a further note; we are not supporting logs & metrics in cSaaS, but we are in AppD Cloud.

Hi @Ryan.Paredez,

Thank you for the response! Just so I understand clearly, does that mean that we cannot use AppDynamics .NET agent to report both OpenTelemetry span data and Application Performance Monitoring (APM) data from the trial version I'm using?

I do see some data injected from OtelCollector trace pipeline from the dashboard:

This is when I used the existing application:

although following the next steps, after I installed the agent it showed that the controller connection is not working so I ended up registered the machine with no application.

Does this mean that at least the flow for # 3 and # 4 on the following diagram is working?

Thank you!

Hi @Yujie.Zhou You are correct the flow of #2, # 3 and # 4 is working for you.

I m not expert in .Net agent but to get #1 flow to work, you need to set the Application name as "opentelemetry" rather than "opentelemetry_otel". Also, note your trial account should have .net or any APM license to get #1 work flow.

For otel flow, the service.namespace name you use "opentelemetry" is translated to "opentelemetry_otel" Application name in the controller to distinguish between otel data and appd data. Ideally you should see 2 applications

1. opentelemetry_otel : For otel related data

2. opentelemetry: For appdynamics instrumented data

Please give it a try and see if that solves the problem. Thanks
