Struct PrometheusPlugin 

pub struct PrometheusPlugin {
    prefer_name: bool,
    metrics: Option<Arc<GatewayMetrics>>,
}

Records a per-consumer request counter against the shared GatewayMetrics; a no-op when metrics are disabled (unit tests).

Fields

prefer_name: bool

Accepted for APISIX config compatibility; inert (see module docs).

metrics: Option<Arc<GatewayMetrics>>

Shared metrics handle from PluginResources; None disables recording.

Implementations

impl PrometheusPlugin

pub fn from_config( config: &HashMap<String, Value>, resources: &Arc<PluginResources>, ) -> Result<Self, String>

Builds the plugin from node config.

Config keys (all optional):

• prefer_name (bool, default false): accepted for parity with APISIX’s prometheus plugin; inert in featherbit (the route label is always the request host — see module docs).

type: prometheus
config:
  prefer_name: true

fn consumer_label(ctx: &Context) -> String

The consumer label for this request: the consumer name attached by an upstream auth node, or anonymous when none is present.

fn route_label(ctx: &Context) -> String

The route label for this request. featherbit has no route object on the context here, so the request host is used (low-cardinality); falls back to unknown when absent.

Trait Implementations

impl Plugin for PrometheusPlugin

fn plugin_type(&self) -> &str

Unique identifier for the plugin type (e.g., “proxy-rewrite”, “upstream”).

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, ctx: Context, _named_inputs: &'life1 HashMap<String, Value>, ) -> Pin<Box<dyn Future<Output = Result<PluginOutput, PluginExecutionError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Executes the plugin logic against the request/response context.
