#define METRIC_RECORD

(

name

)

Value:

static Metric* metrics_h_metric =                                     \
      g_metrics ? g_metrics->NewMetric(name) : NULL;                    \
  ScopedMetric metrics_h_scoped(metrics_h_metric);

The primary interface to metrics.

Use METRIC_RECORD("foobar") at the top of a function to get timing stats recorded for each call of the function.
