Denis Magda created IGNITE-9305: ----------------------------------- Summary: Wrong off-heap size is reported for a node Key: IGNITE-9305 URL: https://issues.apache.org/jira/browse/IGNITE-9305 Project: Ignite Issue Type: Task Affects Versions: 2.6 Reporter: Denis Magda Fix For: 2.7
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): {code} [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] {code} And that weird stuff was reported by the node (pay attention to the last line): {code} [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! {code} Had to change the code by using {code}dataRegion.getPhysicalMemoryPages(){code} to find out that actual off-heap usage size was {code} >>> Physical Memory Size: 28651614208 => 27324 MB, 26 GB {code} The logs have to report the following instead: {code} ^-- Off-heap {Data Region 1} [used={dataRegion1.getPhysicalMemorySize()}, free=X%, comm=dataRegion1.maxSize()] ^-- Off-heap {Data Region 2} [used={dataRegion2.getPhysicalMemorySize()}, free=X%, comm=dataRegion2.maxSize()] {code} If Ignite persistence is enabled then the following extra lines have to be added to see the disk used space: {code} ^-- Off-heap {Data Region 1}: used={dataRegion1.getTotalAllocatedSize() - dataRegion1.getPhysicalMemorySize()} ^-- Off-heap {Data Region 2} [used={dataRegion2.getTotalAllocatedSize() - dataRegion2.getPhysicalMemorySize()}] {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
