[Xymon] How does the vmstat.rrd file get populated?

[greg.shea at emc.com]

Hi all,

I have added 2 channel processes to my Xymon 4.3.3 instance, that reads data from the status and data channels
and writes that data to a file for integration with another product.  I have a Solaris 10 client running a standard build
no bottom-feeders and I have a vmstat.rrd file, but I'm not seeing the vmstat data off my 2 channel processors.

How does the standard Xymon client send the file $XYMONHOME/tmp/xymon_vmstat.hostname.12558 to the
server?  I'm using Henrik's simple shell script and the --processor option on the rrd channels

If I use the bottom feeder scripts, vmstat gets written to my output file.

Thanks and regards
