I’m going mad - Graylog

I think I’m going mad

Getting Graylog up in docker, the host as 7Gig memory, but the keep getting following error

Data Node Heap Size Warning
(triggered 15 minutes ago)
There are data node nodes in the cluster which could potentially run with a higher configured heap size for better performance.
Data node datanode only has 1 GB Java Heap assigned, out of a total of 7 GB RAM.
Currently, there is 6 GB free memory available on the node. We recommend to make an additional half of this available to the Java Heap.
Note: For production performance, it is recommended to configure this node to use 3 GB Java Heap (50% of RAM).
The Java Heap can be configured using the opensearch_heap configuration parameter in the node's configuration file (datanode.conf).

Have set in the datanode container env

OPENSEARCH_JAVA_OPTS: "-Xms3g -Xmx3g”

GRAYLOG_DATANODE_OPENSEARCH_HEAP_SIZE: “3g”

Even mapped datanode.conf with

opensearch_heap_size = 3g

Yet keep getting the Heap size warning.

Am I missing something?

There are two JVM Heap sizes, one for Elasticsearch and one for Graylog. The one you are looking at in web UI is JVM of the Graylog which can be configured in /etc/default/graylog-server file, under GRAYLOG_SERVER_JAVA_OPTS variable. For example to set 1.5GB, change -Xms and -Xmx values to -Xms1536m -Xmx1536m.

Fanks yeah resolved my problem

In the graylog-server container env in docker-compose.yml

GRAYLOG_SERVER_JAVA_OPTS: "-Xms3g -Xmx3g -XX:NewRatio=1 -server -XX:+ResizeTLAB -XX:-OmitStackTraceInFastThrow”
