Metrics.
See the spec
A single metric, measuring some time-varying quantity or statistical distribution. It is composed of one or more data points that have precise values and time stamps. Each distinct metric should have a distinct name.

Emit some metrics to the collector (sync). This blocks until the backend has pushed the metrics into some internal queue, or discarded them.
NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.
