Grafana Loki · Rate Limits

Grafana Loki Rate Limits

Grafana Loki is self-hosted software, so every rate limit is operator-configured per tenant rather than fixed by a vendor. Loki publishes both the limit semantics and the shipped default value for each one in its configuration reference, which is what an agent needs to predict a 429 before it happens. Limits are enforced per tenant (identified by the X-Scope-OrgID header) by the distributor and ingester components.

Grafana Loki Rate Limits is the machine-readable rate-limit profile for Grafana Loki on the APIs.io network, in the API Commons Rate Limits shape.

It captures 14 rate-limit definitions.

Limit state is signalled in the published, note, observed_headers, and retry_after response headers.

Tagged areas include Company, Logs, Logging, Log Aggregation, and Observability.
