/sys/quotas/rate-limit

The /sys/quotas/rate-limit endpoint is used to create, edit and delete rate limit quotas.

Create or update a rate limit quota

This endpoint is used to create a rate limit quota with an identifier, name. A rate limit quota must include a rate value with an optional path that can either be a namespace or mount, and can optionally include a path suffix following the mount to restrict more specific API paths.

Method	Path
POST	/sys/quotas/rate-limit/:name

Parameters

• name (string: "") - The name of the quota.

• path (string: "") - Path of the mount or namespace to apply the quota. A blank path configures a global rate limit quota. For example namespace1/ adds a quota to a full namespace, namespace1/auth/userpass adds a quota to userpass in namespace1, and namespace1/kv-v2/data/foo/bar adds a quota to a specific secret on a K/V v2 mount in namespace1. A trailing glob (*) can also be added as part of the path after the mount to match paths that share the same prefix prior to the glob. namespace1/kv-v2/data/foo/* would match both namespace1/kv-v2/data/foo/bar and namespace1/kv-v2/data/foo/baz. Updating this field on an existing quota can have "moving" effects. For example, updating namespace1 to namespace1/auth/userpass moves this quota from being a namespace quota to a namespace specific mount quota. Non-global quotas are not inherited by child namespaces. Note, namespaces are supported in Enterprise only.

• rate (float: 0.0) - The maximum number of requests in a given interval to be allowed by the quota rule. The rate must be positive.

• interval (string: "") - The duration to enforce rate limiting for (default "1s").

• block_interval (string: "") - If set, when a client reaches a rate limit threshold, the client will be prohibited from any further requests until after the 'block_interval' has elapsed.

• role (string: "") - If set on a quota where path is set to an auth mount with a concept of roles (such as /auth/approle/), this will make the quota restrict login requests to that mount that are made with the specified role. The request will fail if the auth mount does not have a concept of roles, or path is not an auth mount.

• inheritable (bool: false) - If set to true on a quota where path is set to a namespace, the same quota will be cumulatively applied to all child namespace. The inheritable parameter cannot be set to true if the path does not specify a namespace. Only quotas associated with the root namespace quotas are inheritable by default.
