# Observability

| Reference | What it covers |
| [Telemetry and exports](/products/affinidi-trust-fabric/agent-stream/reference/observability/telemetry-and-exports.md) | Exporting traces, metrics, and audit logs over OpenTelemetry, scraping metrics with Prometheus, sending events to a webhook, and reading the usage and rejection data behind the dashboard’s charts. |
| [Response headers](/products/affinidi-trust-fabric/agent-stream/reference/observability/response-headers.md) | Every x-agent-stream-* header on a successful chat response, and whether it appears on a buffered or a streamed response. |
| [Notifications and alerts](/products/affinidi-trust-fabric/agent-stream/reference/observability/notifications-and-alerts.md) | Setting up an alert integration (Slack, email, webhook, or a streaming platform), its per-type delivery fields, and which events route to it. |
| [LLM drift](/products/affinidi-trust-fabric/agent-stream/reference/observability/llm-drift.md) | The Drift Harness settings, the LLM Drift page, the nine drift dimensions, thresholds, regression gating, drift alerts, replay evaluation, and retention. |

## Pages in this section
- [Telemetry and exports](/products/affinidi-trust-fabric/agent-stream/reference/observability/telemetry-and-exports.md): Reference for exporting Agent Stream traces, metrics, and audit logs over OpenTelemetry, scraping metrics with Prometheus, sending events to a webhook, and reading the usage and rejection data behind the dashboard's own charts.
- [Response headers](/products/affinidi-trust-fabric/agent-stream/reference/observability/response-headers.md): Every x-agent-stream-* header a successful chat response carries, and whether it appears on a buffered or a streamed response.
- [Notifications and alerts](/products/affinidi-trust-fabric/agent-stream/reference/observability/notifications-and-alerts.md): Field-level reference for the Integration record, its per-type delivery configuration, and the event-type taxonomy that routes surface, drift, governance, and usage alerts to integrations.
- [LLM drift](/products/affinidi-trust-fabric/agent-stream/reference/observability/llm-drift.md): Field-level reference for the Drift Harness settings, the LLM Drift page, the nine drift dimensions, baseline and threshold mechanics, drift alerts, replay evaluation, and retention.
