Function init_meter_provider 

pub fn init_meter_provider(
    resource: &Resource,
    metrics_interval_secs: u64,
) -> Result<SdkMeterProvider>

Initialize a meter provider for OpenTelemetry metrics.

Arguments

• resource - The OpenTelemetry resource to use.
• metrics_interval_secs - The interval in seconds between metric collections.

Errors

Returns an error if the metric exporter cannot be built. When no OTLP endpoint is configured, or the endpoint env var is empty, the provider is still initialized without a periodic exporter.

Examples

use otel_init::{get_resource, init_meter_provider};
use opentelemetry::KeyValue;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let resource = get_resource("my-service", &[]);
    let meter_provider = init_meter_provider(&resource, 30)?;
    Ok(())
}
