PS5, Line 276: METRIC_DEFINE_gauge_size(table, merged_table_entities_count,
             :                          "Entities Count Merged From",
             :                          kudu::MetricUnit::kEntries,
             :                          "When enabled metrics merge by some 
entity attribute, "
             :                          "and this is a merged entity, this 
metric identify "
             :                          "how many entities it merged from.");
Instead of adding METRIC_DEFINE_gauge_size to every place where 
METRIC_DEFINE_entity is used, could you modify the macro definition for 
METRIC_DEFINE_entity to also call METRIC_DEFINE_gauge_size?
