Retrieve and optionally reset aggregated runtime statistics for all active database connections.

mco_stat_get_conn_stats

Retrieve and optionally reset statistics for a specific database connection or aggregated across all connections of a database.

mco_stat_get_counter_info

Retrieve metadata for a registered runtime statistics counter.

mco_stat_get_histogram_source

Retrieve the internal histogram index associated with a given statistics counter.
