I have allocated 5 GB Non heap memory to Ignite as can be verified at application startup.
[13:09:56] Topology snapshot [ver=1, servers=1, clients=0, CPUs=4, offheap=4.9GB, heap=2.6GB] [13:09:56] ^-- Node [id=AC62049E-CB7B-4BB6-B19D-56C17B695A8D, clusterState=ACTIVE] [13:09:56] Data Regions Configured: [13:09:56] ^-- default [initSize=2.0 GiB, maxSize=3.9 GiB, persistenceEnabled=false] [13:09:56] ^-- Buffer_Region [initSize=512.0 MiB, maxSize=1000.0 MiB, persistenceEnabled=false]
But during the cluster metrics, I get non heap size as -1%.
Metrics for local node (to disable set 'metricsLogFrequency' to 0) ^-- Node [id=ac62049e, name=dm123, uptime=00:07:00.046] ^-- H/N/C [hosts=1, nodes=1, CPUs=4] ^-- CPU [cur=0.33%, avg=2.39%, GC=0%] ^-- PageMemory [pages=158231] ^-- Heap [used=493MB, free=81.32%, comm=960MB] ^-- Non heap [used=112MB, free=-1%, comm=117MB] ^-- Outbound messages queue [size=0] ^-- Public thread pool [active=0, idle=0, qSize=0] ^-- System thread pool [active=0, idle=6, qSize=0]
What is this Non-Heap size, in this metric? How can I get the real non-heap size in use?
Also I don't know what comm
means in the metrics; couldn't find it in documentation either.
