When is the reset _cat/thread_pool statistics?

hello^^

i'm using ES for huge bulk insert job.
after inserting.
i want to know that how many query was rejected.
so, i am using now the following query.

curl '/_cat/thread_pool?v&h=id,host,bulk.active,bulk.queueSize,bulk.queue,bulk.size,bulk.rejected'

look at the bulk.rejected.
but, i don't know the range of statistics time.

when is the start time and end time? and expire time

thank you for reading my article.

please advice for me.

Those stats will be for the life of the JVM - ie when you started ES.

thank you for your replay.
These statistics can it initialized when you restart the ES instance?

They will, yes.

thank you very much!
