Build Status

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

let mut 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 :

  • generic publisher / sources
  • dispatch scopes
  • feature flags
  • late builders
  • microsecond-precision intervals
  • heartbeat metric on publish
  • log templates
  • more outputs adapters
  • configurable aggregation
  • queued dispatch
  • non-aggregating buffers
  • tagged / ad-hoc metrics
  • framework glue (rocket, iron, etc.)
  • tests & benchmarks
