Subject Ignite metrics
Date Fri, 21 Oct 2016 07:38:22 GMT

i have loaded around 20 M records into 4 node ignite cluster.

Following is the ignite metrics logged in the log of one node.

^-- Node [id=c0e3dc45, name=my-grid, uptime=20:17:27:096]
    ^-- H/N/C [hosts=4, nodes=4, CPUs=32]
    ^-- CPU [cur=0.23%, avg=0.26%, GC=0%]
    ^-- Heap [used=999MB, free=71.96%, comm=1819MB]
    ^-- Non heap [used=101MB, free=-1%, comm=105MB]
    ^-- Public thread pool [active=0, idle=16, qSize=0]
    ^-- System thread pool [active=0, idle=16, qSize=0]
    ^-- Outbound messages queue [size=0]

Each node is consuming around 20 gb RAM (can see it from htop command).

Ignite Configuration :

 <property name="cacheMode" value="PARTITIONED"/>
<property name="backups" value="1"/>
<property name="swapEnabled" value="true"/>
<property name="copyOnRead" value="false"/>
<property name="memoryMode" value="OFFHEAP_TIERED"/>
<property name="offHeapMaxMemory" value="0"/>

>From the log, non heap used is 101 MB and heap used is 999MB. But actual
RAM used by jar is 20 GB.

Can you please clarify the numbers ?
