FYI, I am using Ignite 2.16.
I have also been playing with the Ignite metrics. This allows me to see the
numbers of Get()'s for each cache, but I have a suspicion I can't enable it
for existing caches.Is that correct? At least, when I enable it on an
existing system I just get zeros back, but a new system appears to track
the statistics as expected.
Thanks,
Raymond.
