Hi guys! I set up a Graylog instance and everythings it’s working smoothly. After start receiveign a couple of logs I notice that the default JVM Heap size it’s a bit short (1 GB) and I read a little in google to increase it. The prefered way to do it it’s seems to be adding the tag “ES_HEAP_SIZE=…

Hej @Nicodd17 the default file location can be found in out documentation . Just to have it said. If you run a server with 30GB RAM and everything on one box, give Elasticsearch ~12GB Heap and Graylog ~2GB - said that you will have some Memory left for the OS and everything else.

As you have Graylog and Elasticsearch you are able to modify the HEAP for both. It looks like you mixed in your mind both up. What did you like todo? Raise the HEAP for which one? Why did you want to raise the heap?

Thanks for the replay and the clarification Jan! I wanted to raise the HEAP for Elastix because I read that it needs the 50% of the RAM in order to have a good performance and avoid bottlenecks as I’m going to start feeding it with a lot of logs. So, the HEAP size in Graylog is it good if I leaved…

Thanks for the help Jan, everything set up correctly now. Cheers!

@Nicodd17 So just to be sure did you ever get a clear answer; what is the meaning of A and B when you do the curl call? [image] Thanks ~B

These are simply the Java heap memory stats of the Elasticsearch nodes in that particular cluster. If you add name and id to the h parameter of the cat nodes API request, you will also see which nodes these are specifically.

bingo! thank you heap.current heap.percent heap.max id name 759mb 46 1.5gb 6GiP graylog-c14015b6-b090-4e4c-a37a-2b5f3b241cc9 1.7gb 22 7.9gb 50_0 Pulse

So the web interface GUI shows us the “Pulse” node graphically but not the elasticsearch? What is “Pulse” and what is “graylog-c14015b6-b090-4e4c-a37a-2b5f3b241cc9”? The math matches up if I assume that’s what the GUI shows me. What about that area which is NOT used up (circled in blue): [image] …

You’re mixing things up. “Pulse” is the name of your Elasticsearch node, “graylog-c14015b6-b090-4e4c-a37a-2b5f3b241cc9” is the name of the embedded Elasticsearch node inside your Graylog process (the name is simply a concatenation of “graylog-” and the node ID). The chart on the web interface show…

Hello, I got the same situation as bubba198 does and then the same question > What about that area which is NOT used up (circled in blue) Thanks!

That’s the maximum amount of heap memory the JVM will allocate if required. Check the -Xms and -Xmx parameters in the JVM.
