[Xymon] Question on rrd parsing of disk report

[Deiss, Mark]

I am running into an issue with my 4.33 and 4.37 Xymon servers with the
received disk test results. I am running cases of either the BB df test
or the Xymonclient module that reports df results. In both cases, the
header line from the df output is being processed into an rrd database
file and into graph entries (on 4.33 and 4.37 servers).

I am not seeing this bahaviour with the Xymon demo site; the df header
line is appearing in the disk detail web page; the graphs look fine
there.

Which file(s) should I be looking at where the df header line should be
suppressed for rrd purposes? I thought maybe this would be defined in
one of the configuration files but now am thinking it may be explicitly
handled in of the C binaries.

Googling around I see where there is mention of special filters required
for usage with custom scripts but no mention on how the standard tests
are being massaged to eliminate chaff lines.
