dipstick

A fast and modular metrics library decoupling app instrumentation from reporting backend. Similar to popular logging frameworks, but with counters and timers. Can be configured for combined outputs (log + statsd), random sampling, local aggregation of metrics, recurrent background publication, etc.

Design

Dipstick's design goals are to:

• support as many metrics backends as possible while favoring none
• support all types of applications, from embedded to servers
• promote metrics conventions that facilitate app monitoring and maintenance
• stay out of the way in the code and at runtime (ergonomic, fast, resilient)

Code

Here's a short example of sending timer values to the log showing both closure and macro syntax

use dipstick::*;
let metrics = metrics(log("app_metrics"));
let timer = metrics.timer("timer_b");
let value1 = timer.time(||, compute_value1());
let value2 = time!(timer, compute_value2());

More complete example(s?) can be found in the /examples dir.

TODO

Although already usable, Dipstick is still under heavy development and makes no guarantees of any kind at this point. See the following list for any potential caveats :

• META turn TODOs into GitHub issues
• cool logo
• generic publisher / sources
• dispatch scopes
• feature flags
• non-tokio scheduler
• late builders
• microsecond-precision intervals
• heartbeat metric on publish
• logger templates
• more outputs adapters
• configurable aggregation
• queued dispatch
• non-aggregating buffers
• tagged / ad-hoc metrics
• framework glue (rocket, iron, etc.)
• tests & benchmarks
• complete doc / inline samples
• example applications
