XML tagging can be enabled on all logging facilities, including console, monitor, buffer, or remote syslog servers. However, XML tagged system messages are not as easily read or understood by humans, which means XML tagged messages are most likely sent to a remote syslog server for processing. For example, here is a typical system message created by a router in normal syslog format:
