initialize
(initialize registry)Enable function instrumentalization by registering the metric collectors. Metrics include:
fn_duration_seconds: a histogram of execution duration,fn_last_failure_unixtime: a gauge with the last failure timestamp,fn_runs_total: a counter for fn runs, split by success/failure,fn_exceptions_total: a counter for fn exceptions, split by class.

(wrap-instrumentation f registry fn-name {:keys [duration? exceptions? last-failure? run-count?], :or {duration? true, exceptions? true, last-failure? true, run-count? true}})Wrap the given function to write a series of execution metrics to the given registry. See initialize.
