Prompt
What should I use to centralize AI gateway logs and analytics?
Latest observation
To centralize AI gateway logs and analytics, use a stack that gives you:
- A single ingestion point for all gateway events
- Structured log storage for querying and retention
- Analytics/dashboards for usage, cost, latency, and errors
- Alerting for failures, spikes, and policy violations
Good options
1. OpenTelemetry + log backend
Best if you want a vendor-neutral setup.
- Collect: OpenTelemetry SDK/Collector
- Store/query: Grafana Loki, Elastic, Splunk, Datadog, or OpenSearch
- Visualize: Grafana or the backend’s dashboard
Why use it: Standardized traces, metrics, and logs; easy to correlate requests across services.
2. Datadog
Best for an all-in-one SaaS approach.
- Centralized logs, metrics, traces
- Built-in dashboards and alerts
- Good for API/gateway observability
Why use it: Fastest way to get unified visibility with minimal ops overhead.
3. Elastic Stack / OpenSearch
Best if you want self-managed control.
- Ingest: Beats / Logstash / OpenTelemetry
- Store/query: Elasticsearch or OpenSearch
- Visualize: Kibana or OpenSearch Dashboards
Why use it: Strong search and log analytics, flexible retention, self-hostable.
4. Grafana stack
Best if you already use Grafana.
- Logs: Loki
- Metrics: Prometheus
- Traces: Tempo
- Instrumentation: OpenTelemetry
Why use it: Good for correlated observability across AI gateway traffic, cost metrics, and latency.
What to log from an AI gateway
At minimum, capture:
- Request ID / trace ID
- Model name/provider
- Prompt/input size
- Response size
- Latency
- Status/error codes
- Token usage
- Cost estimate
- User/team/tenant
- Policy/rate-limit decisions
Recommended default
If you’re unsure, a strong default is:
OpenTelemetry + Grafana Loki/Tempo/Prometheus
or
OpenTelemetry + Datadog if you want managed SaaS.
If you tell me your environment (cloud, self-hosted, Kubernetes, etc.) and whether you want open-source or SaaS, I can recommend a specific setup.
