Broadcast

​

Add a destination

1. Open Settings → Broadcast and choose a destination.
2. Enter its credentials. They are encrypted before storage and never shown again.
3. Choose what to send (see Choose what is sent).
4. Select Test Connection. Phaseo sends a sample trace the way real deliveries are sent, so a failure here shows the destination’s own error.
5. Save. Requests that finish after this are sent within about a minute.

​

Choose what is sent

• Privacy Mode leaves prompts, outputs, system instructions, and tool definitions out of every trace. Requests made with an API key that never stores content are never forwarded with content, whatever this setting says.
• Generation Metadata, Cost, Identity, and Request Context each turn a group of span attributes on or off. Turning off Request Context also drops request metadata.
• Rate sends a share of eligible requests, from 0 to 1. The choice is stable for each request and destination, so a retried delivery is never sampled differently.
• Filter by API key includes or excludes requests made with specific keys.
• Filter Rules send only requests that match. Rules compare fields such as model, provider, user ID, finish reason, cost, or token counts, and can be grouped with and and or. Matches regex uses a linear-time engine: back-references and lookaround are not supported, and a pattern that is too large is rejected when you save it.

Add your own trace context

{
  "model": "openai/gpt-5-nano",
  "messages": [{ "role": "user", "content": "Summarise this ticket" }],
  "metadata": {
    "trace_id": "ticket-48213",
    "trace_name": "support-summary",
    "generation_name": "summarise",
    "customer_tier": "enterprise"
  }
}

Object storage and warehouse rows

​

Object storage

• Amazon S3: an access key that can s3:PutObject on the bucket, and the bucket’s region. For an S3-compatible store, set S3-Compatible Endpoint.
• Cloudflare R2: an R2 API token’s access key ID and secret, your account ID, and the jurisdiction if the bucket is in one (eu or fedramp).
• Google Cloud Storage: an HMAC key for a service account that can create objects in the bucket.
