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 *;
let metrics = metrics;
let timer = metrics.timer;
let value1 = timer.time;
let value2 = time!;
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
