Ignite metrics

[Anil <an...@gmail.com>]

HI,

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 ?

Thanks

Hi Anil,

The row (Non heap) does not contains information about cache. If you want
to see how many memory was used by particular cache.

You can switch up metrics for it:

*<bean class="org.apache.ignite.configuration.CacheConfiguration"> *
* <property name="statisticsEnabled" value="true"/>*
...

and tracking a metrics of cache by API:

*ignite.cache("name").metrics().getOffHeapAllocatedSize()*

or by JMX bean.
