Igniters, Suppose, Dmitry is talking about IGNITE-5583 [1] - `Switch non-heap memory metrics to new page memory semantics` and related previous disscustions to it [4].
Also we have some additional improvements to CacheMetrics: IGNITE-5490 [2] - `Implement replacement for obsolete CacheMetrics#getOffHeapAllocatedSize` IGNITE-5765 [3] - `CacheMetrics interface cleanup, documentation and fixes` [1] https://issues.apache.org/jira/browse/IGNITE-5583 [2] https://issues.apache.org/jira/browse/IGNITE-5490 [3] https://issues.apache.org/jira/browse/IGNITE-5765 [4] http://apache-ignite-developers.2346864.n4.nabble.com/Negative-non-heap-memory-maximum-td17990.html On Fri, 17 Aug 2018 at 10:14 Dmitriy Pavlov <dpavlov....@gmail.com> wrote: > Hi Igniters, > > It is not an easy fix, so I'm not sure it is possible to do in 2.7. > > Offheap size is not reported by VM (it returns -1).
