dipstick

A one-stop shop metrics library for Rust applications with lots of features,
minimal impact on applications and a choice of output to downstream systems.

Features

Dipstick is a toolkit to help all sorts of application collect and send out metrics. As such, it needs a bit of set up to suit one's needs. Skimming through the handbook handbook should help you get an idea of the possible configurations.

In short, dipstick-enabled apps can:

• Send metrics to console, log, statsd, graphite or prometheus (one or many)
• Serve metrics over HTTP
• Locally aggregate the count, sum, mean, min, max and rate of metric values
• Publish aggregated metrics, on schedule or programmatically
• Customize output statistics and formatting
• Define global or scoped (e.g. per request) metrics
• Statistically sample metrics (statsd)
• Choose between sync or async operation
• Choose between buffered or immediate output
• Switch between metric backends at runtime

For convenience, dipstick builds on stable Rust with minimal, feature-gated dependencies.

Non-goals

For performance reasons, dipstick will not

• plot graphs
• send alerts
• track histograms

These are all best done by downstream timeseries visualization and monitoring tools.

Show me the code!

Here's a basic aggregating & auto-publish counter metric:

let bucket = Bucket::new();
bucket.set_target(Text::output(io::stdout()));
bucket.flush_every(Duration::from_secs(3));
let counter = bucket.counter("counter_a");
counter.count(8)

Persistent apps wanting to declare static metrics will prefer using the metrics! macro:

metrics! { METRICS = "my_app" =>
    pub COUNTER: Counter = "my_counter";
}

fn main() {
    METRICS.set_target(Graphite::output("graphite.com:2003").unwrap());
    COUNTER.count(32);
}

For sample applications see the examples. For documentation see the handbook.
