wazuh dashboard not started

[Maha]

Dear team,

This is a fresh installation of Wazuh OVA. Only changed the network details to static ip.

Tried restarting the services.

Any reasons why its not getting started.

Thank you.

Attaching screenshots.

Hi Maha,

The IP will depend on the cert files. I believe in OVA It will be the localhost. By default, Wazuh will work using the IP from its host. So unless you set a specific IP address before setting the static IP, you should be able to connect to your server. We need to check the logs to find out why it is not working.
Please share the Indexer logs to check your issue further.

cat /var/log/wazuh-indexer/wazuh-cluster.log | grep -i -E "error|warn"
or
cat /var/log/wazuh-indexer/<indexer_log_file_name> | grep -i -E "error|warn"

Hi  Maha,

First, try to solve the issue of the indexer.

I have noticed that you having HeapDumpOnOutOfMemoryError issue due to not having enough RAM.

Hardware requirements: https://documentation.wazuh.com/current/quickstart.html#hardware

I suggest you expand your RAM and configure the heap memory accordingly.
Here are some key points to keep in mind to configure heap memory:
Use no more than 50% of your available RAM.
Don’t set the heap size over 32 GB.

Start by checking your memory with:
free -h

Then, update the heap size in the /etc/wazuh-indexer/jvm.options file. For example, if your server has 12 GB of RAM, set the heap size to 6 GB as shown below:
-Xms6g
-Xmx6g

After making these changes, restart the Wazuh indexer for them to take effect:
systemctl restart wazuh-indexer

Let us know the update.

I am needing to change the heap size regularly. Is there an fix for this.

My server is having 8GB of RAM so i set the heap size to 4GB. but after restart i am required to change it again.

Thank you.
