combination

Send metrics to multiple outputs:

let _app_metrics = metric_scope((
        to_stdout(), 
        to_statsd("localhost:8125")?.with_namespace(&["my", "app"])
    ));

buffering

sampling

Apply statistical sampling to metrics:

let _app_metrics = to_statsd("server:8125")?.with_sampling_rate(0.01);

A fast random algorithm (PCG32) is used to pick samples. Outputs can use sample rate to expand or format published data.
