class MetricEventLogger

Defined at line 2929 of file fidling/gen/sdk/fidl/fuchsia.metrics/fuchsia.metrics/hlcpp/fuchsia/metrics/cpp/fidl.h

A logger for events that are associated with one project's metrics.

Public Methods

void ~MetricEventLogger ()

void LogOccurrence (uint32_t metric_id, uint64_t count, ::std::vector<uint32_t> event_codes, LogOccurrenceCallback callback)

Logs the fact that an event has occurred a number of times.

`metric_id` ID of the metric being logged.

`count` The number of times the event has occurred. The value should

be positive as a value of 0 is ignored.

`event_codes` Ordered list of parameters, one for each of the metric's

dimensions. Occurrence counts with the same event codes are aggregated

based on these parameters.

void LogInteger (uint32_t metric_id, int64_t value, ::std::vector<uint32_t> event_codes, LogIntegerCallback callback)

Logs an integer measurement.

`metric_id` ID of the metric being logged.

`value` The integer measurement.

`event_codes` Ordered list of parameters, one for each of the metric's

dimensions. Integer values with the same event codes are aggregated

based on these parameters.

void LogIntegerHistogram (uint32_t metric_id, ::std::vector< ::fuchsia::metrics::HistogramBucket> histogram, ::std::vector<uint32_t> event_codes, LogIntegerHistogramCallback callback)

Logs a histogram giving many approximate integer measurements.

`metric_id` ID of the metric being logged.

`histogram` The collection of approximate integer measurements. Buckets

that have no measurement (empty buckets) should not be sent.

`event_codes` Ordered list of parameters, one for each of the metric's

dimensions. Histograms with the same event codes are aggregated together

based on these parameters.

void LogString (uint32_t metric_id, ::std::string string_value, ::std::vector<uint32_t> event_codes, LogStringCallback callback)

Logs a string value that was observed.

`metric_id` ID of the metric being logged.

`string_value` The string to log.

`event_codes` Ordered list of parameters, one for each of the metric's

dimensions. Counts of logged strings are aggregated separately based on

these parameters.

void LogMetricEvents (::std::vector< ::fuchsia::metrics::MetricEvent> events, LogMetricEventsCallback callback)

Bulk logging method, equivalent to making many of the above Log*() calls

at once.
