Struct ExporterBuilder

pub struct ExporterBuilder { /* private fields */ }

PrometheusExporter configuration options

Implementations

impl ExporterBuilder

pub fn without_units(self) -> Self

Disables exporter’s addition of unit suffixes to metric names.

By default, metric names include a unit suffix to follow Prometheus naming conventions. For example, the counter metric request.duration, with unit ms would become request_duration_milliseconds_total.

With this option set, the name would instead be request_duration_total.

pub fn without_counter_suffixes(self) -> Self

Disables exporter’s addition _total suffixes on counters.

By default, metric names include a _total suffix to follow Prometheus naming conventions. For example, the counter metric happy.people would become happy_people_total. With this option set, the name would instead be happy_people.

pub fn without_target_info(self) -> Self

Configures the exporter to not export the resource target_info metric.

If not specified, the exporter will create a target_info metric containing the metrics’ Resource attributes.

pub fn without_scope_info(self) -> Self

Configures the exporter to not export the otel_scope_info metric.

If not specified, the exporter will create a otel_scope_info metric containing the metrics’ Instrumentation Scope, and also add labels about Instrumentation Scope to all metric points.

pub fn with_namespace(self, namespace: impl Into<String>) -> Self

Configures the exporter to prefix metrics with the given namespace.

Metrics such as target_info and otel_scope_info are not prefixed since these have special behavior based on their name.

pub fn with_registry(self, registry: Registry) -> Self

Configures which prometheus::Registry the exporter will use.

If no registry is specified, the prometheus default is used.

pub fn with_resource_selector( self, resource_selector: impl Into<ResourceSelector>, ) -> Self

Configures whether to export resource as attributes with every metric.

Note that this is orthogonal to the target_info metric, which can be disabled using without_target_info.

If you called without_target_info and with_resource_selector with ResourceSelector::None, resource will not be exported at all.

pub fn build(self) -> MetricResult<PrometheusExporter>

Creates a new PrometheusExporter from this configuration.
