Setup​

End to End Video Walkthrough​

This video walks through the entire process of setting up LiteLLM with CloudZero integration and viewing LiteLLM exported usage data in CloudZero.

Step 1: Configure Environment Variables​

Set your CloudZero credentials in your environment:

export CLOUDZERO_API_KEY="cz_api_xxxxxxxxxx"
export CLOUDZERO_CONNECTION_ID="conn_xxxxxxxxxx"
export CLOUDZERO_TIMEZONE="UTC"  # Optional, defaults to UTC

Step 2: Enable CloudZero Integration​

Add the CloudZero callback to your LiteLLM configuration YAML file:

model_list:
  - model_name: gpt-4o
    litellm_params:
      model: openai/gpt-4o
      api_key: sk-xxxxxxx

litellm_settings:
  callbacks: ["cloudzero"]  # Enable CloudZero integration

Step 3: Start LiteLLM Proxy​

Start your LiteLLM proxy with the configuration:

litellm --config /path/to/config.yaml

Setup on UI​

1. Click "Settings"

2. Click "Logging & Alerts"

3. Click "CloudZero Cost Tracking"

4. Click "Add CloudZero Integration"

5. Enter your CloudZero API Key.

6. Enter your CloudZero Connection ID.

7. Click "Create"

8. Test your payload with "Run Dry Run Simulation"

10. Click "Export Data Now" to export to CLoudZero

Testing Your Setup​

Dry Run Export​

Call the dry run endpoint to test your CloudZero configuration without sending data to CloudZero. This endpoint will not send any data to CloudZero, but will return the data that would be exported.

curl -X POST "http://localhost:4000/cloudzero/dry-run" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "limit": 10
  }' | jq

Expected Response:

{
  "message": "CloudZero dry run export completed successfully.",
  "status": "success",
  "dry_run_data": {
    "usage_data": [...],
    "cbf_data": [...],
    "summary": {
      "total_cost": 0.05,
      "total_tokens": 1250,
      "total_records": 10
    }
  }
}

Manual Export​

Call the export endpoint to send data immediately to CloudZero. We suggest setting a small limit to test the export. This will only export the last 10 records to CloudZero. Note: Cloudzero can take up to 15 minutes to process the exported data.

curl -X POST "http://localhost:4000/cloudzero/export" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "limit": 10
  }' | jq

Expected Response:

{
  "message": "CloudZero export completed successfully",
  "status": "success"
}

Data Export Details​

Automatic Export Schedule​

  • Frequency: Every 60 minutes (configurable via CLOUDZERO_EXPORT_INTERVAL_MINUTES)
  • Data Processing: LiteLLM automatically processes and exports usage data hourly
  • CloudZero Processing: CloudZero typically takes 10-15 minutes to process data from LiteLLM

Data Format​

LiteLLM exports data in CloudZero Billing Format (CBF) with the following structure:

{
  "time/usage_start": "2024-01-15T14:00:00Z",
  "cost/cost": 0.002,
  "usage/amount": 150,
  "usage/units": "tokens",
  "resource/id": "czrn:litellm:openai:cross-region:team-123:llm-usage:gpt-4o",
  "resource/service": "litellm",
  "resource/account": "team-123",
  "resource/region": "cross-region",
  "resource/usage_family": "llm-usage",
  "resource/tag:provider": "openai",
  "resource/tag:model": "gpt-4o",
  "resource/tag:prompt_tokens": "100",
  "resource/tag:completion_tokens": "50"
}

Resource Tagging​

LiteLLM automatically creates comprehensive resource tags for cost attribution:

  • Provider Tags: openai, anthropic, azure, etc.
  • Model Tags: Specific model names like gpt-4o, claude-3-sonnet
  • Team/User Tags: Team IDs and user IDs for cost allocation
  • Token Breakdown: Separate tracking of prompt and completion tokens
  • Usage Metrics: Total tokens consumed per request

Advanced Configuration​

Custom Export Frequency​

Change the export frequency (not recommended to go below 60 minutes):

export CLOUDZERO_EXPORT_INTERVAL_MINUTES=120  # Export every 2 hours

Custom Time Range Export​

Export data for a specific time range:

curl -X POST "http://localhost:4000/cloudzero/export" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "start_time_utc": "2024-01-15T00:00:00Z",
    "end_time_utc": "2024-01-15T23:59:59Z",
    "operation": "replace_hourly"
  }' | jq

Troubleshooting​

Common Issues​

  1. Missing Credentials Error

    CloudZero configuration missing. Please set CLOUDZERO_API_KEY and CLOUDZERO_CONNECTION_ID environment variables.

    Solution: Ensure both environment variables are set with valid values.

  2. Connection Issues

    • Verify your CloudZero API key is valid
    • Check that the connection ID exists in your CloudZero account
    • Ensure your proxy has internet access to reach CloudZero's API

  3. No Data in CloudZero

    • CloudZero can take 10-15 minutes to process data
    • Check that your LiteLLM proxy is generating usage data
    • Use the dry-run endpoint to verify data is being formatted correctly
