Float64 returns a pointer to the float64 value passed in.

Float64Value returns the value of the float64 pointer passed in or 0 if the pointer is nil.

NewAggregator returns a new Aggregator.

NewClass returns a new Class for the class ID and fingerprint.

NewMetrics returns a pointer to an initialized Metrics structure.

Uint64 returns a pointer to the uint64 value passed in.

Uint64Value returns the value of the uint64 pointer passed in or 0 if the pointer is nil.

MaxExampleBytes defines to how many bytes truncate a query.

TruncatedExampleSuffix is added to truncated query.

An Aggregator groups events by class ID.

BoolStats are boolean-based metrics like QC_Hit and Filesort.

A Class represents all events with the same fingerprint and class ID.

A Example is a real query and its database, timestamp, and Query_time.

Metrics encapsulate the metrics of an event like Query_time and Rows_sent.

NumberStats are integer-based metrics like Rows_sent and Merge_passes.

A Result contains a global class and per-ID classes with finalized metric statistics.

TimeStats are microsecond-based metrics like Query_time and Lock_time.
