Hello,
To see those logs, you need to enable the logall option in the global section of the ossec.conf file and restart the manager, if everything is good, the manager should be running fine.
This option allows Wazuh to store in /var/ossec/logs/archives/archives.log every event generated, doesn't matter if it generated an alert or not.
Using the events stored there, you will be able to create your own rules and decoders, you can have more information about it here:
