Instance Method Details

#get_stats(metric_name, _ = true, scoped_metric_only = false, scope = nil) ⇒ Object

Deprecated.

Use Mmtrix::Agent#record_metric instead.

This method is deprecated and not thread safe, and should not be used by any new client code. Use Mmtrix::Agent.record_metric instead.

If scoped_metric_only is true, only a scoped metric is created (used by rendering metrics which by definition are per controller only) Leaving second, unused parameter for compatibility
