Duplicate query/time metric for same query on broker

Hi,

I have enabled monitoring and metrics on the broker. I fired 32 group by queries in parallel. I see that for some query’s query/time metric is produced around 5 times. For 32 queries I got a total of 56 query/time metrics on druid/broker service. Is this expected? Shouldn’t it be just 32 metrics for 32 queries?

Total queries - 32

Unique query ids on druid/broker - 32

Total count of query/time on broker - 56.

I can see for some specific queryId’s the count is 5 for some it’s 3 and 2 and for most its 1.

Druid version - 0.0.12

Any insights are appreciated.

Thanks
