Artsiom Panko commented on IGNITE-12507:
----------------------------------------

[~ivan.glukos], can you provide any steps to reproduce "When all data is in RAM [...] the only things that *could be watched* on is number of keys in partition on a specific node and memory usage metrics on the machine."
And what is the difference between "... cache size in bytes metric for pure in-memory case." and "... and memory usage metrics on the machine."?

> There is a need to have cache size in bytes metric for pure in-memory case.
> When all data is in RAM, it is not obvious to find out exactly how much space is consumed by cache data on a running node as the only things that could be watched on is number of keys in partition on a specific node and memory usage metrics on the machine.
