Renamed to reset!, here for backwards compatibility with 3rd-party gems (though this really isn't part of the public API). @deprecated

Like tl_record_unscoped_metrics
, but records a scoped metric as well.
This is an internal method, subject to change at any time. Client apps and gems should use the public API (TingYun::Agent.record_metric
) instead.
The given scoped_metric will be recoded as both a scoped and an unscoped metric. The summary_metrics will be recorded as unscoped metrics only.
If called during a transaction, all metrics will be attached to the Transaction
, and not merged into the global set of metrics until the end of the transaction.
If called outside of a transaction, only the unscoped metrics will be recorded, directly into the global set of metrics (under a lock).

Update the unscoped metrics given in metric_names. metric_names may be either a single name, or an array of names.
This is an internal method, subject to change at any time. Client apps and gems should use the public API (TingYun::Agent.record_metric
) instead.
There are four ways to use this method:
-
With a numeric value, it will update the Stats objects associated with the given metrics by calling record_data_point(value, aux). aux will be treated in this case as the exclusive time associated with the call being recorded.
-
With a value of :apdex_s, :apdex_t, or :apdex_f, it will treat the associated stats as an Apdex metric, updating it to reflect the occurrence of a transaction falling into the given category. The aux value in this case should be the apdex threshold used in bucketing the request.
-
If a block is given, value and aux will be ignored, and instead the Stats object associated with each named unscoped metric will be yielded to the block for customized update logic.
-
If value is a Stats instance, it will be merged into the Stats associated with each named unscoped metric.
If this method is called during a transaction, the metrics will be attached to the Transaction
, and not merged into the global set until the end of the transaction.
Otherwise, the metrics will be recorded directly into the global set of metrics, under a lock.
