Set up Arize Phoenix to trace agent execution and view performance data in your Phoenix dashboard. Before starting, complete the quickstart guide to have an agent running on Idun Agent Platform.

​
Set up Phoenix observability

1

Get your Phoenix details

  1. Go to Arize Phoenix
  2. Sign up or log in to your account
  3. Create a new project or select an existing one
  4. Note your Project Name and the Collector Endpoint (typically https://collector.phoenix.com)
2

Create an observability configuration

  1. On the Idun Agent Platform main page, navigate to Observability
  2. Click Add configuration
  3. Select Phoenix
  4. Enter a Configuration Name (for example, “Phoenix Prod”)
  5. Fill in the required details:
    • Collector Endpoint: The URL of the Phoenix collector (for example, https://collector.phoenix.com or your custom endpoint)
    • Project Name: The name of your project in Phoenix
  6. Click Create configuration
Observability configurations are saved and reusable across multiple agents.
3

Attach Phoenix to your agent

  1. Navigate to the agent you want to trace
  2. Click Edit Agent
  3. Click Next to reach the observability configuration step
  4. Select Phoenix as the observability provider
  5. Select the Phoenix configuration you want to use
  6. Click Next
  7. Click Save changes to finalize
After saving, click Restart on your agent page to reload the configuration and enable Phoenix observability.

​
View observability data

Once your agent is running with observability enabled:
  1. Interact with your agent through the Manager UI or API
  2. Open your Phoenix dashboard
  3. Navigate to your project to view traces
You will see traces showing agent execution flows, tool usage, and latency data.

​
Best practices

  • Use descriptive names for observability configurations
  • Monitor latency using Phoenix’s performance tools
  • Check traces regularly to understand agent behavior

​
Troubleshooting

ADK does not currently support simultaneous tracing with multiple providers.

​
Observability not working?

  1. Check collector endpoint: Verify the URL is correct and accessible from the agent environment
  2. Verify project name: Confirm it matches the project name in Phoenix exactly
  3. Check network: Confirm your agent environment can reach the Phoenix collector
