Hello,

I have to configured appdynamic with ruby on rails, I have added gem "gem ‘appdynamics’ " in gemfile, also created appdynamics.yml file with following details:

app\_name: “My app name” tier\_name: “ROR” node\_name: “test” controller: host: “test” port: “test” account: “test” access\_key: “some key”

Also please do let me know how will I get **app\_name, tier\_name, node\_name, controller, host, port, account, access\_key.**

I am getting this error:

1. WARN – AppDynamics: Unable to start Instrumenter due to a configuration error: app name required
2. AppDynamics: [AppDynamics] [1.1.2] Running AppDynamics in development mode. No data will be reported until you deploy your app.

Thanks

This request is eerily similar to [Shubham Thakur’s question two and a half years ago](https://community.appdynamics.com/t5/Dynamic-Languages-Node-JS-Python/configuration-error-app-name-required/td-p/38293) on Cisco’s forums.

At any rate, consider that AppDynamics is being sunsetted by Cisco, and they are encouraging folks to transition to [their OpenTelemetry offering](https://docs.appdynamics.com/appd/22.x/latest/en/application-monitoring/appdynamics-for-opentelemetry/instrument-applications-with-appdynamics-for-opentelemetry), which involves using these gems:

```ruby
gem 'opentelemetry-sdk'
gem 'opentelemetry-exporter-otlp'
gem 'opentelemetry-instrumentation-all'

```
