Struct MetricMirroring 

pub struct MetricMirroring {
    pub enabled: bool,
    pub allowlist: Vec<String>,
}

Which metrics are mirrored to the failover region.

The two settings are grouped because they are consumed together: the routing state of the failover metrics pipeline is derived from both at once. A consumer that watched them separately could rebuild that state from a fresh value of one and a stale value of the other, describing a configuration that was never published; a live view of this struct delivers both from one configuration version instead.

Fields

enabled: bool

Whether metrics are mirrored to the failover region.

Defaults to false. Mirroring also requires Domain::enabled, but unlike it this setting is read live, which is the point of it: an operator starts and stops mirroring on a running process.

allowlist: Vec<String>

Metrics permitted to be sent to the failover region.

Defaults to empty, which mirrors every metric rather than none: the list narrows mirroring, it does not enable it. Names match exactly. Read live, alongside enabled, so an operator can restrict mirroring to the metrics the failover region needs without restarting.

Trait Implementations

impl Clone for MetricMirroring

fn clone(&self) -> MetricMirroring

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricMirroring

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

Formats the value using the given formatter.

impl Default for MetricMirroring

fn default() -> MetricMirroring

Returns the “default value” for a type.

impl PartialEq for MetricMirroring

fn eq(&self, other: &MetricMirroring) -> 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 MetricMirroring

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
