Crate 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.

Modules

aggregate	Maintain aggregated metrics for deferred reporting,
app	This module regroups the application metrics front-end.
cache	Cache defined metrics.
core	Dipstick metrics core types and traits. This is mostly centered around the backend. Application-facing types are in the app module.
fnsink	A mechanism to dynamically define new sink implementations.
macros	Publicly exposed metric macros are defined here. Although dipstick does not have a macro-based API, in some situations they can make instrumented code simpler.
multi	Dispatch metrics to multiple sinks.
output	Standard stateless metric outputs.
publish	Publishes metrics values from a source to a sink.
queue	Queue metrics for write on a separate thread, Metrics definitions are still synchronous. If queue size is exceeded, calling code reverts to blocking.
sampling	Reduce the amount of data to process or transfer by statistically dropping some of it.
statsd	Send metrics to a statsd server.

Macros

time	A convenience macro to wrap a block or an expression with a start / stop timer. Elapsed time is sent to the supplied statsd client after the computation has been performed. Expression result (if any) is transparently returned.
