template <typename... DimensionTypes>
void LogOccurrence (DimensionTypes... dimensions)

Log event with fuchsia.metrics.MetricEventLogger with the provided parameters. If the service

is not accessible, keep the parameters to try again later.

Defined at line 41 of file ../../src/developer/forensics/utils/cobalt/logger.h

template <typename DimensionType>
void LogCount (DimensionType dimension, uint64_t count)

Log event with fuchsia.metrics.MetricEventLogger with the provided parameters. If the service

is not accessible, keep the parameters to try again later.

Defined at line 48 of file ../../src/developer/forensics/utils/cobalt/logger.h

template <typename DimensionType>
void LogElapsedTime (DimensionType dimension, uint64_t timer_id)

Log the time elapsed in microseconds since starting the timer with id |timer_id| with

fuchsia.metrics.MetricEventLogger. If the service is not accessible, keep the parameters to

try again later.

This does not stop the timer.

template <typename DimensionType>
void LogDuration (DimensionType dimension, zx::duration duration)

Log a duration in microseconds. If the service is not accessible, keep the parameters to try

again later.
