Subject Re: What information does FetchRequestAndResponseMetrics name contain?
Date Mon, 02 Jun 2014 19:01:19 GMT
Hi Jun Rao, thx for quick answer. That means I can see at the same time
values like :

af-servers-ConsumerFetcherThread-af-servers-wawanawna-Dell-1401353748289-
*fcaaea28*-0-0-host_localhost-my-port_9092-FetchRequestRateAndTimeMs

and

af-servers-ConsumerFetcherThread-af-servers-wawanawna-Dell-1401353748289-
*fcaaea29*-0-0-host_localhost-my-port_9092-FetchRequestRateAndTimeMs

I see that '*fcaaea29*'  is something like UUID, but UUID of what? Just
UUID for separating one name from another? Does that mean we can see
exactly the same name except this UUID part?



And maybe next combination also possible?

af-servers-ConsumerFetcherThread-af-servers-wawanawna-Dell-
1401353748289-fcaaea29-0-*0*-host_localhost-my-port_9092-
FetchRequestRateAndTimeMs

and

af-servers-ConsumerFetcherThread-af-servers-wawanawna-Dell-
1401353748289-fcaaea29-0-*1*-host_localhost-my-port_9092-
FetchRequestRateAndTimeMs

???

Why we need 'brokerId' in name if we already have broker host+port? Does
that mean we can see different 'brokerId' for the same host+port ?

Thx.
