About Grafana Mimir tenant IDs

Within a Grafana Mimir cluster, the tenant ID is the unique identifier of a tenant. For information about how Grafana Mimir components use tenant IDs, refer to Authentication and authorization.

Restrictions

Tenant IDs must be less-than or equal-to 150 bytes or characters in length and can only include the following supported characters:

  • Alphanumeric characters
    • 0-9
    • a-z
    • A-Z
  • Special characters
    • Exclamation point (!)
    • Hyphen (-)
    • Underscore (_)
    • Single period (.)
    • Asterisk (*)
    • Single quote (')
    • Open parenthesis (()
    • Close parenthesis ())

Note

For security reasons, . and .. aren’t valid tenant IDs.

Note

__mimir_cluster isn’t a valid tenant ID because Mimir uses the name internally.

All other characters, including slashes and whitespace, aren’t supported.
