Cache Metrics

[Akash Shinde <ak...@gmail.com>]

Hi,
 I have captured below two ignite cache metrics.

1) igniteCache.metrics().getSize()
2)igniteCache  .metrics().getOffHeapEntriesCount()

I started three nodes with distrusted load.
When I started filling the cache I observed OffHeapEntries counts are
approximately double
of cache size.

Why offHeapEntries count are approximately double?
Is offHeapEntries includes primary count plus backup counts?

Thanks,
Akash

Hello!

Yes, I assume that offHeapEntries == primaries + backups.

Hello,

This doesn't sound well, could you give a bit more detail on this case? How
many entries did you load (what are the counts), which Ignite version do you
use, and if possible a minimalistic reproducing snippet for this issue.

Also, .getSize() is deprecated now, are you able to use .getCacheSize()
instead and check if it returns correct value?

Regards,
Anton
