starting at 1. Multiple matching definitions are separated by one or more empty
lines. The first mapping rule that matches a StatsD metric wins.
Metrics that don't match any mapping in the configuration file are translated
into Prometheus metrics without any labels and with certain characters escaped
(`_` -> `__`; `-` -> `__`; `.` -> `_`).
In general, the different metric types are translated as follows, with certain
suffixes appended to the Prometheus metric names:
StatsD gauge -> Prometheus gauge (suffix `_gauge`)
StatsD counter -> Prometheus counter (suffix `_counter`)
StatsD timer -> Prometheus summary (suffix `_timer`) <-- indicates timer quantiles
-> Prometheus counter (suffix `_timer_total`) <-- indicates total time spent
-> Prometheus counter (suffix `_timer_count`) <-- indicates total number of timer events
