The man page for xymond_rrd talks about the "ncv" part only being used for status messages. But this is a long-shot.</span></div>

If you're sending gauge data and it's being treated as counter data, then you will often get mostly zeroes or NaN. By default, NCV data is expected to be DERIVE which is a type of counter. If you want to change to GAUGE, then you need to set NCV_columnname to describe this:</div>
<div><br></div><div>NCV_columnname="foo:GAUGE,bar:GAUGE"</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

</blockquote><div><br></div><div>Perhaps. These seem a lot trickier to use.</div><div><br></div><div>One thought I had about this was to setup "--extra-test" and "--extra-script" on the status channel, to filter out the status messages from xymond_rrd. If you use "--extra-script=/bin/true" and "--extra-test=columnname" then I think it will feed the data to "/bin/true" instead of parsing it itself. Of course "/bin/true" will produce no output, and hence no data.</div>
