AdvertisedChainMetrics

reth_discv5::metrics

Struct AdvertisedChainMetrics 

Source 
pub struct AdvertisedChainMetrics { /* private fields */ }
Expand description

Tracks frequency of networks that are advertised by discovered peers.

Peers advertise the chain they belong to as a kv-pair in their node record, using the network as key.

Implementations§

Source§

impl AdvertisedChainMetrics

Source

pub fn new_with_labels(labels: impl IntoLabels) -> Self

Creates a new instance of the metrics with the provided labels.

Unlike Self::default, this does not cache the result, so it can be used to re-register metrics or register with different labels.

Source

pub fn describe()

Describe all exposed metrics.

Internally, this calls the describe_* macros from the metrics crate according to the metric type.

This is done only once, to avoid multiple describe calls to the same recorder. If this is not preferred, you can call Self::force_describe directly.

See: https://docs.rs/metrics/latest/metrics/index.html#macros

Source

pub fn force_describe()

Unconditionally describes all metrics.

See Self::describe.

Source§

impl AdvertisedChainMetrics

Source

pub fn increment_once_by_network_type(&self, enr: &Enr)

Counts each recognised network stack type that is advertised on node record, once.

Source§

impl Default for AdvertisedChainMetrics

Source§

fn default() -> Self

Creates a new instance of the metrics.

This initializes all metrics and registers them with the global recorder. Metrics are described only once; see Self::describe.

The result is cached in a static OnceLock, so subsequent calls will return a clone of the same instance.
