Hi Rotiv134,
Thank you for using Wazuh,
First, let me ask you, did you restart the elasticsearch service?
We can check the following commands to make sure the filebeat is configured correctly in your manager and try to restart the service. This command will show if there are any errors in the service:
Systemctl status elasticsearch
To ensure that Filebeat is correctly configured, run the following command:
filebeat test output
You should see an output as it shows in the attached image.
Have you upgraded the Kibana? If not here are the steps on how to upgrade it:
Please let me know the output
Best Regards.
