How to decode audit log?

I want to know which command were used from proctitle:

# ausearch -k monitor-hosts

Decode proctitle with xxd command:

$ echo 63686D6F64006F2B72002F7661722F6C6F672F706163656D616B65722F62756E646C65732F7261626269746D712D62756E646C652D322F | xxd -r -p; echo
chmodo+r/var/log/pacemaker/bundles/rabbitmq-bundle-2/

Now we know the file permission change was caused by command chmod +r /var/log/pacemaker/bundles/rabbitmq-bundle-2/
