How to start the elastic search process. It's not mentioned in the Appd Documentation; Events service installation part.

Hi @Nour.Alghamdi,
Can you share what documentation you were looking at? I'll share it with the Docs team to see if we can get changes made to it.
In the meantime, I'm also looking around to see what I can find.

Hi Ryan,

Please find the link:

https://docs.appdynamics.com/appd/onprem/latest/en/events-service-deployment/install-the-events-service-on-linux

Tell me where to find the helpful information, After 10 hours of troubleshooting we found that we need to set the following variables:
export JAVA_HOME={Installation dir}/product/events-service/processor/jre/bin
export INSTALL_BOOTSTRAP_MASTER_ES8=true

Thanks for your consideration.

Regards

Hi @Nour.Alghamdi,

Thanks for sharing the Doc link. Just to be clear, you found the solution and you no longer need help?

Yes Thanks Ryan,

now we have another problem with the elasticsearch, it gets crashes on memory usage. head hs_err_pid512833.log
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 16384 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full

so what should be our memory GB to run the ES

Hi @Nour.Alghamdi,

Did you ever get a solution from Support? I did hear back from Docs and this is what they told me.

"Events service will take care of bringing up the elastic search"
