Defines backend-specific metric reader configuration for OtelBridge.
OtelBridge.Profile exists so application metric definitions can stay
backend-agnostic.
A profile takes a backend choice such as VictoriaMetrics and turns it into
the metric reader configuration expected by :opentelemetry_experimental.
This keeps export details out of business modules and out of most call sites.
When you need this module
Use a profile when:
- you want a named helper such as
:victoria_metrics - you want a reusable module that builds a metric reader map
- you want backend-specific defaults to live in one place
If you do not need a profile abstraction, you can configure the
OpenTelemetry SDK directly and use otel_bridge only for metrics bridging.
Example
config :opentelemetry_experimental,
readers: [
OtelBridge.metric_reader!(:victoria_metrics,
export_interval_ms: 5_000,
endpoint: "http://localhost:4318"
)
