AuxCounters & benchmark modes

[Nitsan Wakart]

I used Overseer and reported via AuxCounters. It is rather unpleasant as it requires the Overseer implementation independently and is not well packaged in any way. The solution to different events names etc is also rather crude. But it works for a specific case.
Having JMH deal with this for me would be awesome, when is it coming?

I'm not saying they are *very* bad. :) But, in current form, they are a
bit of the nuisance, which can become a large nuisance if we try to
further abuse them.

I know about this one, and this easily tied into throughput/averagetime
modes.

Can you elaborate on this? Do you actually feed the HWC data through
@AuxCounters, or it is just an idea? The reason I ask is that HWC
profilers integration should be the next big thing in JMH.
