CPU of SkyWalking oap is increasing day by day

[peacine]

deployment：docker
oap version：9.5.0
storage type：es 7.10
other config is default

The traffic is stable, but the usage of cpu has grown several times。

Any other infos require？

You at least should profile the JVM. This graph doesn't mean anything. Memory could increase due to higher payload, slower of DB performance, etc.

About Kafka partition, I think so, or, sometimes, more partitions per OAP may be better. I don't think, as I said, I am not a kafka in the patten.

Thanks. How about the first question. I found the frequent gc, but dont know how to solve it. Keeping increasing xmx and xms(6g->8g)? Current Java options is "-Dmode=no-init -Xmx6g -Xms6g"

I don't know that. There's not a good memory parameter thing.
It relies on your JVM experiences.
Maybe bigger is better.
Ask your own dev or platform team Java experts.

I see.Thank you.
Wish you a good day.

About memory, for JVM 17/21, it is common to setup 20-30g memory for high payload, with 12-16 vCPU.

Thanks very much.
