Struct Domain 

pub struct Domain {
    pub metric_allowlists: HashMap<String, Vec<String>>,
    pub metric_prefix_allowlists: HashMap<String, Vec<String>>,
}

Resolved configuration for selectively routing metrics to configured intakes.

Fields

metric_allowlists: HashMap<String, Vec<String>>

Exact metric names permitted to reach each configured intake.

Defaults to an empty map, which leaves ordinary endpoint routing unchanged. Keys must exactly match the configured primary endpoint or an entry in additional_endpoints. Each value is a case-sensitive exact-name allowlist covering both series and sketches. Metrics matching either this list or metric_prefix_allowlists are forwarded. If both lists for a selected endpoint are empty, all metrics to that endpoint are dropped. Operators can use this to reduce metric volume at selected destinations. Changes require a restart.

metric_prefix_allowlists: HashMap<String, Vec<String>>

Permits metrics whose names start with a configured literal prefix to reach each intake.

Defaults to an empty map, which adds no prefix policies and leaves metric_allowlists unchanged. Keys must exactly match the configured primary endpoint or an entry in additional_endpoints. Both series and sketches are forwarded when their normalized names match either an exact name in metric_allowlists or one of these prefixes. Matching is case-sensitive and treats every configured character literally.

An empty string matches every valid metric name. If both lists for a selected endpoint are empty, all metrics to that endpoint are dropped. Endpoints absent from both maps retain ordinary routing.

Trait Implementations

impl Clone for Domain

fn clone(&self) -> Domain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Domain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Domain

fn default() -> Domain

Returns the “default value” for a type.

impl PartialEq for Domain

fn eq(&self, other: &Domain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Domain

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
