Documented steps
Read https://developers.cloudflare.com/ai-gateway/observability/logging/ and https://developers.cloudflare.com/ai-gateway/observability/analytics/ before changing settings.
Logging is on by default per gateway and stores request/response payloads as well as metadata. Adjust it in AI > AI Gateway > {gateway} > Settings > Logs.
Override per request with headers 'cf-aig-collect-log' (bypass the gateway-level logging setting) and 'cf-aig-collect-log-payload' (keep token counts, cost and duration while suppressing raw prompt/response bodies).
Fetch one log's request detail over REST: GET https://api.cloudflare.com/client/v4/accounts/{account_id}/ai_gateway/gateways/{gateway_id}/logs/{log_id}/request using an AI Gateway-scoped API token.
For aggregate metrics (requests, tokens, cost, errors, cached rate) query the GraphQL Analytics API node 'aiGatewayRequestsAdaptiveGroups' with datetimeHour_geq / datetimeHour_leq filters, or read the dashboard charts.
For long-term export, set up Workers Logpush (Workers Paid required): generate an RSA key pair, upload the public key in the gateway's Logpush settings while logging is enabled, create the Logpush job, then decrypt the delivered logs locally with your private key. Reference: https://developers.cloudflare.com/ai-gateway/observability/logging/logpush/
Track stored-log volume against the plan cap so logging does not silently stop.
Known gotchas
Stored logs are capped at 10 million per gateway on paid plans and 100,000 per account on Free. Once the cap is reached new logs stop being saved until older ones are deleted; there is no eviction rotation to rely on.
Individual stored log size is capped at 10 MB; Logpush-exported logs are capped at 1 MB each, so large payloads are handled differently by the two paths.
Log storage is rate-limited to 500 logs per second per gateway.
Only 4 Logpush jobs are allowed per account and Logpush requires the Workers Paid plan.
Prompts and completions are stored by default. If the gateway carries regulated or personal data, set 'cf-aig-collect-log-payload' or disable payload logging before the first production request, not after.
There is no documented bulk list-logs REST endpoint; the REST call requires an exact log_id. Use GraphQL for programmatic aggregate analysis.
