Victoriametrics Rate Limits

VictoriaMetrics is self-hosted (or VictoriaMetrics Cloud as a managed service); there is no managed REST quota in OSS. Operational caps are set via flags on each component (-search.maxConcurrentRequests, -search.maxQueryDuration, -insert.maxQueueDuration, -maxConcurrentInserts, -maxLabelsPerTimeseries, etc.). Enterprise multi-tenancy adds per-tenant cardinality / ingestion / query rate limits enforced at vminsert and vmselect.

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

It captures 5 rate-limit definitions, measuring concurrent_requests, ms, concurrent_inserts, active_series, and samples_per_second.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled and busy.

Tagged areas include Database, Time-Series, Monitoring, Open Source, and Prometheus.
