Struct opendal::layers::MetricsLayer

pub struct MetricsLayer;

MetricsLayer will add metrics for OpenDAL.

Metrics

• opendal_requests_total: Total requests numbers
• opendal_requests_duration_seconds: Request duration seconds.
  • NOTE: this metric tracks the duration of the OpenDAL’s function call, not the underlying http request duration

Labels

Most metrics will carry the following labels

• service: Service name from Scheme
• operation: Operation name from Operation

Examples

use anyhow::Result;
use opendal::layers::MetricsLayer;
use opendal::Operator;
use opendal::Scheme;

let _ = Operator::from_env(Scheme::Fs)
    .expect("must init")
    .layer(MetricsLayer);
