holochain_metrics

Provides instrumentation to measure, publish, collect, aggregate, and analyze performance metrics from log files or cloudwatch.

Usage

Instrumentation

Use the with_latency_publishing! macro to wrap existing rust functions with latency calculations. Or more generally just invoke the publisher with your own metrics.

use holochain_metrics::{Metric, LoggerMetricPublisher};

fn main() {

    let publisher = LoggerMetricPublisher::default();
    let metric = Metric:new("request_size", 1000.0);
    publisher.publish(&metric);

}
