<div dir="ltr"><div><div><div><div>As Jeremy said, the number after the ::, is the number of data sets (lines) per graph.<br></div>In the case of my example, we are generating a stack graph, of all CPU usage, so it will only look useful if all the datasets are graphed.

<br></div>However, if you set that to something sane, like 4 or 5, you will only see 4 or 5 lines per graph, and multiple graphs will appear if necessary.<br><br></div>Regards<br></div>Vernon<br></div><div class="gmail_extra">

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>

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>
