Questions about enriched format and Node on RHEL 7.4

[Maupertuis Philippe]

Hi,
With Rhel 7.4 just out, I am giving a try at the new audit.
Something seems strange to me.
With the default log_format = RAW in auditd.conf, I get the node= parameter right in rsyslog (through the syslog plugin).
If I switch to log_format = ENRICHED the parameter is missing altogether (no node=)

In both case local there is no node parameter in the local audit.log.
When I run ausearch --format text  from the  local host I never get node information.
When I run it from the data received by rsyslog (after stripping the prefix with sed 's/^.*audispd://'), I get the node information for the RAW format only.

Another point that bothers me is that I got an extra line did-unknown after each meaningful line when I use the remote content (RAW or ENRICHED)
This is what I get locally
At 16:03:55 07/08/17 fr18358, acting as root, successfully executed /bin/pkg-config
At 16:03:55 07/08/17 fr18358, acting as root, successfully executed /usr/libexec/grepconf.sh
At 16:03:55 07/08/17 fr18358, acting as root, successfully opened-file /dev/tty using grepconf.sh
At 16:03:55 07/08/17 fr18358, acting as root, successfully executed /bin/grep
This is what I get from remote data
At 15:43:52 07/08/17 fr18358, acting as root, successfully executed /bin/pkg-config
At 15:43:52 07/08/17  did-unknown
At 15:43:52 07/08/17 fr18358, acting as root, successfully executed /usr/libexec/grepconf.sh
At 15:43:52 07/08/17  did-unknown
At 15:43:52 07/08/17 fr18358, acting as root, successfully opened-file /dev/tty using grepconf.sh
At 15:43:52 07/08/17  did-unknown
At 15:43:52 07/08/17 fr18358, acting as root, successfully executed /bin/grep

Please tell me what I am doing wrong.
Philippe
