Hello Meraz,
Did you try to enable archive logging on the Wazuh server to verify whether the logs are being received? If you haven't done this, enable archive logging on the Wazuh server using the below procedures. Archive logs captures all events, regardless of whether they trigger a rule or not:
- Go to the file /var/ossec/etc/ossec.conf and enable <logall> and <logall_json> (screenshot attached).
- Save the changes and restart the Wazuh manager service systemctl restart wazuh-manager
- You can then monitor the archive.log file tail -f /var/ossec/logs/archives/archives.log
After checking the logs, and you see them being received, send to us the sample logs for us to be able to assist you with custom decoder and rules. Do not forget to disable archive logging after getting the sample logs.
If you didn't see the logs there, check for error entries on the Wazuh server's
ossec.log file by running the command
cat /var/ossec/logs/ossec.log | grep -i -E "error|warn|crit"Kindly update us with the outcome so as to know the next step to take.
Best regards.
