Hi Josh
The host's client seems to be behaving as if it's running in local mode rather than central mode. In local mode, the host's OS metrics (CPU, disk, etc) are reported as individual "status" type messages. In central mode, the metrics are compiled into the client message log and sent as a single "client" type message.
It's been a while since I looked into running a Xymon client in local mode. I believe you can find the current mode from the xymonlaunch process list, like so:
$ sudo -u xymon strings /proc/`pgrep xymonlaunch`/environ | grep ^LOCALMODE
This will output "yes" if running in local mode, and "no" if running in central mode. The client runs in local mode when LOCALMODE is set to "yes". I believe this is set in the file xymonclient.cfg, which is typically located in $XYMONHOME/etc/.
Cheers
