<div dir="ltr">I'm trying to add a new graph to a test using NCV
(SPLITNCV actually). I read through the graphing tips, I read
several emails that provided hints (not my exact problem but
nudged me the right way)...
<div><br>
</div>
<div>long story short. I finally got he graph to show up on my
test page...but the rrd file doesn't seem to be populating the
fields as expected when I run "rrdtool dump". The only thing
I can figure is that the test I'm performing doesn't run every
5 minutes but every 15 minutes. Does that matter? I would
have expected in the worst case that only every 3rd row would
have a value.</div>
<div><br>
</div>
<div>What am I missing here? Note, I dropped my test to run
every 5 minutes to see if this theory is true.</div>

Is the DS type DERIVE or COUNTER? In that case two successive
samples, which are 5 minutes apart, are needed to create one data
point in the graph.<br>

<div>As a side note, it would be extremely helpful if the NCV
component didn't look at the entire status but required a
comment block (for example) to contain it. That way you could
keep your data stream isolated from your message. For
example:</div>
<div><br>
</div>
<div><!-- NCV data</div>
<div>metric1: 123</div>
<div>metric2: 456</div>
<div>etc</div>
<div>--></div>
</div>

Perhaps you can use the devmon format, which encapsulates the data
to trend in an HTML comment section. In that case, one would have to
specify "test=devmon" in stead of "test=ncv" in variable TEST2RRD.
There is no need for an NCV_Something variable, as the DS definition
is included with the data to trend.<br>

<div>My test kept creating an rrd file for a date string that
was part of the status message. That's a bit annoying.</div>

There are (at least) two ways to circumvent that problem:<br>
A) Add "*:NONE" to the NCV_Something variable;<br>
B) Replace all occurrences of ":" and "=" outside the NCV part by
their HTML equivalent, thus ":" and "=".<br>
