(SOLVED) 4GB+ heap Size for Elasticsearch

Hello,
would extending the heap size help sensei to run smoother?
From another product this helped me a lot.
And if yes can you tell me where to set this on opnsense?
jvm.option - but here i found several.
thanks
armin

Hi @Armin,
Yes, that should help. Can you try
/usr/local/etc/elasticsearch/jvm.options
file?

Hello,
thank you for your swift answer!
i did change the file and restarted elasticsearch through the web gui
Sensei is set to Small II (50 Devices)
root@opnsense:~ # top | grep java
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
54544 elasticsea 77 52 0 4058M
2339M
uwait 5 0:31 0.20% java
How much would be the max here or would a bigger value make sense at all?

Hi @armin, my pleasure.
For 50 devices, I think that's ok. Elastic will claim more memory only if it needs to.
For a side note, for Elastisearch, cpu performance is also important. This is because of the inverted indexes which are mainly used for aggregations. These are cpu intensive.
Below is a good tutorial on this:

Thanks again!
Funny thing is that medium was blocked by Sensei as i disabled it on the app blocker :-S
I will check your article but for my home environment i think i will have enough CPU power. intel i7 4 Cores HT
Just wanted to waste some of 32 GB RAM
