Igniters, Was troubleshooting an Ignite deployment today and couldn't find out from the logs what was the actual off-heap space used.
Those were the given memory resoures (Ignite 2.6): [2018-08-16 15:07:49,961][INFO ][main][GridDiscoveryManager] Topology snapshot [ver=1, servers=1, clients=0, CPUs=64, *offheap=30.0GB*, heap=24.0GB] And that weird stuff was reported by the node (pay attention to the last line): [2018-08-16 15:45:50,211][INFO ][grid-timeout-worker-#135%cluster_31-Dec-2017%][IgniteKernal%cluster_31-Dec-2017] Metrics for local node (to disable set 'metricsLogFrequency' to 0) ^-- Node [id=c033026e, name=cluster_31-Dec-2017, uptime=00:38:00.257] ^-- H/N/C [hosts=1, nodes=1, CPUs=64] ^-- CPU [cur=0.03%, avg=5.54%, GC=0%] ^-- PageMemory [pages=6997377] ^-- Heap [used=9706MB, free=61.18%, comm=22384MB] * ^-- Non heap [used=144MB, free=-1%, comm=148MB] - this line is always the same!* Had to change the code by using dataRegion.getPhysicalMemoryPages() to find out that actual off-heap usage size was >>> Physical Memory Size: 28651614208 => 27324 MB, 26 GB Let's fix this issue in 2.7, I proposed a new format.
