Viewing Guardrail Results in Logs

Section titled “Viewing Guardrail Results in Logs”

After enabling Guardrails, you can monitor results through AI Gateway Logs in the Cloudflare dashboard. Guardrail logs are marked with a green shield icon, and each logged request includes an eventID, which links to its corresponding Guardrail evaluation log(s) for easy tracking. Logs are generated for all requests, including those that pass Guardrail checks.
