Aria Operations for Logs are not sending the tag to the syslog endpoint after setting the tags under the Log Forwarding in Log Management.
Aria Operations for Logs 8.x
To check if the Aria Operations for Logs is sending the tags correctly, we will need to install tcpdump in the environment.
tdnf install tcpdump
tcpdump -v -s 0 -A dst <syslogserver_ipaddress> and dst port 514
If the tags are configured in Log Forwarding page under Log Management, you should be able to see the tags withint the log events being captured by the tcpdump.
